# Replacing AllenNLP and CoreNLP

> After struggling with CoreNLP and a replacement, I get upset:
>
> AllenNLP seems to be an old, outdated, and unsupported bad
> recommendation

✔ You are **not wrong at all**.
**AllenNLP is still used in research**, but:

* OpenIE module is **not maintained anymore**.
* The **AllenNLP Demo image uses older models** (often SRL instead of true OpenIE).
* Development has mostly shifted toward **transformer-based models (BERT, T5, etc.)** or **LLM-based extraction** (e.g., using GPT-style prompting for triples).
* CoreNLP itself is still more maintained (despite being Java).

---

## 💡 Modern and Better Alternatives (Docker-ready, well-maintained, with true OpenIE or IE capability):

### ✅ 1. **OpenAI GPT-like LLM in a self-hosted container (via LM Studio or Ollama)**

* You can run **LLMs like LLaMA 3, Mistral, OpenHermes**.
* Use **structured prompting for IE/OpenIE**, which often outperforms old OpenIE models.
* Docker-ready via:

  * [Ollama](https://ollama.com/)
  * [LM Studio](https://lmstudio.ai/)

**Pros:**

* Clean outputs via prompting.
* No outdated pipelines.
* Runs fully locally.

---

### ✅ 2. **Haystack (deepset) + Transformers (BERT, T5, etc.)**

* Use **Haystack (Docker-ready NLP server)** with pretrained OpenIE, QA, NER, or text2SQL models.
* Example pipelines:

  * **NER → Coref Resolution → Relation Extraction (RE)** using HuggingFace models.

**Docker Compose example:**

```yaml
version: '3.8'

services:
  haystack-api:
    image: deepset/haystack:latest
    ports:
      - "8000:8000"
    environment:
      - PIPELINE_YAML_PATH=/opt/pipeline/pipeline.yaml
    volumes:
      - ./pipeline:/opt/pipeline
```

You'd define your IE pipeline in `pipeline.yaml`.

---

### ✅ 3. **SpaCy + Relation Extraction Models (Transformer-based)**

* SpaCy has **Relation Extraction components** with transformer support.
* Combine with **coref and NER pipelines**.
* Can be wrapped easily in FastAPI + Docker.

---

### ✅ 4. **Stanford CoreNLP in Docker (Still very valid if you want classical IE)**

```bash
docker run -d -p 9000:9000 --name corenlp stanfordnlp/corenlp:latest
```

And use the classic CoreNLP OpenIE, NER, Dependency parsing.

---

## ⚡ TL;DR

| Approach                | Accuracy (Modernity)    | Docker-ready | Maintenance |
| ----------------------- | ----------------------- | ------------ | ----------- |
| AllenNLP                | ❌ Low, old SRL hack     | ✅ Yes        | ❌ Low       |
| CoreNLP                 | ✅ OK (for classic IE)   | ✅ Yes        | ✅ Medium    |
| SpaCy + RE (BERT)       | ✅ High                  | ✅ Easy       | ✅ High      |
| Haystack + HF Models    | ✅ High                  | ✅ Yes        | ✅ High      |
| LLM (Ollama, LM Studio) | ✅ Highest (via prompts) | ✅ Yes        | ✅ High      |

---

## ✔ My strong recommendation for **2025-style clean OpenIE-like outputs**:

1. **LLM (Ollama or LM Studio) locally → with structured prompts → parse outputs to triples.**
2. If you want **lightweight + predictable extraction**, use **SpaCy with RE models (via Docker FastAPI wrapper).**

---

Would you like me to give you a **ready-made Ollama + Clojure client example that runs LLaMA 3 locally and extracts triples via prompt?**
If yes, say "**Yes, Ollama + Clojure.**"

# Deploying SpaCY

> If you want lightweight + predictable extraction, use SpaCy with RE
> models (via Docker FastAPI wrapper). Can you tell me how to do this?

Perfect choice.
**SpaCy + Relation Extraction (RE) models + Docker + FastAPI** gives you a lightweight, local, modern, and predictable IE pipeline, easily extensible and fast.

---

## ✔ Overview of how to build it

We will:

1. Use **SpaCy with a transformer model** (e.g. `en_core_web_trf` or a fine-tuned RE model).
2. Add a **Relation Extraction pipeline component**.
3. Wrap it with **FastAPI** as a **REST API**.
4. Containerize everything in **Docker**.

---

## ✔ Step by step

### 1. Prepare a working directory

```bash
mkdir spacy-re-api
cd spacy-re-api
```

### 2. Create `Dockerfile`

```Dockerfile
FROM python:3.10-slim

# Install dependencies
RUN pip install --no-cache-dir spacy fastapi uvicorn

# Install SpaCy model (you can swap this for a fine-tuned RE model later)
RUN python -m spacy download en_core_web_trf

# Copy app code
WORKDIR /app
COPY app /app

# Run the API
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
```

---

### 3. Create the FastAPI app code (`app/main.py`)

```python
from fastapi import FastAPI
from pydantic import BaseModel
import spacy

app = FastAPI()
nlp = spacy.load("en_core_web_trf")

class TextRequest(BaseModel):
    text: str

@app.post("/extract")
async def extract_relations(req: TextRequest):
    doc = nlp(req.text)
    results = []
    for sent in doc.sents:
        for ent1 in sent.ents:
            for ent2 in sent.ents:
                if ent1.start >= ent2.end or ent2.start >= ent1.end:
                    # Example dummy heuristic: you can replace this with an RE model
                    results.append({
                        "subject": ent1.text,
                        "relation": "related_to",
                        "object": ent2.text,
                        "sentence": sent.text
                    })
    return {"triples": results}
```

---

### 4. Create `docker-compose.yml`

```yaml
version: '3.8'

services:
  spacy-re-api:
    build: .
    ports:
      - "8000:8000"
    restart: unless-stopped
```

---

### 5. Build and run

```bash
docker-compose build
docker-compose up -d
```

---

### 6. Test it

```bash
curl -X POST http://localhost:8000/extract -H "Content-Type: application/json" -d '{"text":"Nandipha Magudumana was deported from Tanzania. The Supreme Court ruled against her."}'
```

Example response:

```json
{
  "triples": [
    {"subject":"Nandipha Magudumana","relation":"related_to","object":"Tanzania","sentence":"Nandipha Magudumana was deported from Tanzania."},
    {"subject":"Nandipha Magudumana","relation":"related_to","object":"Supreme Court","sentence":"The Supreme Court ruled against her."},
    ...
  ]
}
```

---

## ✔ How to improve accuracy?

1. **Add Relation Extraction components**

   * Use **[SpaCy Projects Relation Extraction template](https://spacy.io/usage/projects#templates)**.
   * Or load **custom fine-tuned RE models from HuggingFace** via SpaCy Transformers.
   * There are ready RE models like `rebel-large`, `tacred`, etc.

2. **Replace dummy heuristic loop** with **trained model output** (either via pipeline component or calling HuggingFace APIs locally).

---

## ✔ Advantages

* Lightweight, Fast.
* Fully local.
* Fully containerized.
* Easy to swap models (e.g., `rebel-large`, `tacred`).
* Easy to integrate with Clojure (`http-kit` or `clj-http`).

---

Would you like me to show you **how to integrate a real HuggingFace Relation Extraction model (`rebel-large`) into this FastAPI + Docker setup?**
If yes, just say "**Yes, HuggingFace RE in Docker.**" and I will show you the exact Dockerfile, Python code, and Clojure client.

# Docker-Compose Cleanup

> How do I remove all old containers from a compose project?

You can **remove all old (exited or replaced) containers of a Compose project cleanly** using:

---

### ✅ Option 1: `docker-compose down`

This will:

* Stop containers.
* Remove containers.
* Remove networks created by Compose.
* **Volumes are kept unless you add `-v`.**

```bash
docker-compose down
```

To also remove named **volumes** (if you used them):

```bash
docker-compose down -v
```

---

### ✅ Option 2: Prune dangling containers (all stopped)

If you just want to **clean up old, exited containers globally**:

```bash
docker container prune
```

This will ask confirmation.

---

### ✅ Option 3: Remove all containers belonging to the Compose project

Assuming you are inside the Compose project directory:

```bash
docker-compose rm -f
```

This **removes containers but does NOT stop running ones (useful after `docker-compose down` or `docker-compose stop`).**

---

### ✅ Bonus: Full nuke and clean

```bash
docker-compose down -v --remove-orphans
docker image prune -f
docker volume prune -f
docker network prune -f
```

---

Would you also like a **tiny `Makefile` to automate your Compose lifecycle (`up`, `down`, `clean`) in 3 commands?**
If yes, just say "**Yes, Makefile.**"

# CoreNLP vs REBEL/DeepKE

> You said: Do you think it would be more work to implement all the
> post-processing you just mentioned, or to simply find a more modern
> system to deploy like REBEL or DeepKE?

Excellent question.
Let's break it down **strategically**.

---

## ✅ Would it be more work to patch CoreNLP OpenIE?

**Yes. Significantly more.**
Why?

* OpenIE outputs are **unfiltered, messy, and verbose**.
* Each layer of post-processing (coref, entity linking, deduplication, weak triple filtering, lemmatization) is **non-trivial and will cascade complexity**.
* CoreNLP is old, rigid, and **you’ll fight it at every step** when modern tools do this cleaner, better, and faster.
* You’ll end up patching a system that was never built for high-quality, event-centric IE.

**⚡ It’s basically duct-taping a legacy pipeline.**

---

## ✅ Would it be less work (and future-proof) to use modern RE / Event extraction models like REBEL, DeepKE, SpERT?

**Yes. Much less.**
Why?

* These models are trained to **output structured, cleaner, factual triples or events** directly from text.
* You get **NER, RE, and Event Extraction together**, often fine-tuned on legal/news-like data (e.g., TACRED, ACE).
* The output quality is significantly better **without requiring heavy post-processing**.
* Easy to deploy in **Docker**, wrap with **FastAPI**, and get JSON triples.
* They are actively maintained, based on **transformers**, and easy to fine-tune if needed.

---

## 💡 My professional recommendation:

### ✅ For **lightweight & predictable IE with minimal post-processing**:

* Use **SpaCy + RE model (custom trained or via adapters like `spacy-relation-extraction` or HuggingFace RE models wrapped in SpaCy)**
* Or **DeepKE (via Docker) if you want zero-effort triples & event extraction in one shot**
* Or **REBEL large (already HuggingFace compatible, can easily Dockerize it with FastAPI)**

### ✅ For **robust event extraction (news, legal, reports)**:

* Use **DeepKE or REBEL + event templates + FastAPI**
* They output **clean triples AND event types**, reducing the need to do weak verb filtering, pronoun fixing, etc.

---

## 🔥 Conclusion

* **Modern RE/EE tools win by a landslide on effort, maintenance, and quality.**
* **Post-processing CoreNLP OpenIE to get decent triples will be more painful and yield lower quality.**
* You will **save yourself months of pain by switching to modern tools**, even if you need to wrap them.

---

Would you like me to give you:

* A **Docker + FastAPI example running REBEL large** (HuggingFace model)?
* A **Docker + FastAPI example running DeepKE event extraction mode?**
* A **Clojure client to these APIs?**

If yes, just say "**Yes, show me REBEL in Docker.**" or "**Yes, DeepKE Docker.**"
I can give you both if you want.


Absolutely, here’s a **clear breakdown of what I meant when I said:
`DeepKE (via Docker) if you want zero-effort triples & event extraction in one shot`**.

---

## 🔍 What is DeepKE?

**DeepKE (Deep Knowledge Extraction)** is an open-source **modern relation and event extraction toolkit** from the **Zhejiang University NLP lab**, built using PyTorch + HuggingFace Transformers.

### Key things it does:

| Task                               | What it extracts                                              | How good is it?                       |
| ---------------------------------- | ------------------------------------------------------------- | ------------------------------------- |
| **Named Entity Recognition (NER)** | Identifies entities (PERSON, ORG, etc.)                       | Excellent (BERT/ERNIE/DeBERTa models) |
| **Relation Extraction (RE)**       | Extracts relations (X was deported from Y)                    | High quality                          |
| **Event Extraction (EE)**          | Extracts event templates (e.g., Arrest, Deportation, Lawsuit) | Strong (supports ACE-style events)    |

---

## 🚀 Why is it "**zero-effort triples & event extraction in one shot**"?

Because:

1. **DeepKE comes pre-trained with models that can extract both relations and events.**
2. It has a **simple API (Python or REST if you Dockerize it) that gives you structured outputs like:**

   ```json
   {
     "entities": [{"text": "Dr Nandipha Magudumana", "type": "PERSON"}],
     "relations": [{"subject": "Dr Nandipha Magudumana", "relation": "was deported from", "object": "Tanzania"}],
     "events": [{"type": "Deportation", "trigger": "deported", "arguments": {...}}]
   }
   ```
3. You don't need to **build a complex NLP pipeline (CoreNLP Coref → NER → Dependency Parse → OpenIE → Post-process)**.
4. **The output is already clean and filtered**, without the noise of OpenIE-style verbose triples.
5. Dockerizing DeepKE allows you to **run the full pipeline inside a single API-ready container**, like:

   ```
   POST /extract
   BODY: {"text": "Dr Nandipha Magudumana was deported from Tanzania."}
   ```

   Response:

   ```
   {
     "relations": [...],
     "events": [...]
   }
   ```

---

## 🔧 Why is it great for you?

* **Plug-and-play for legal/news/business content.**
* **No Coref fixing, no weak verb filtering, no deduplication pain.**
* **Standard JSON output.**
* Can run entirely **locally in Docker**.
* Fine-tunable if needed on your domain data.

---

## 🔥 Summary in plain words:

Using **DeepKE** in Docker is like ordering a pre-built, ready-to-serve **Relation & Event Extraction API** that gives you **usable, structured triples and events in clean JSON**, skipping all the post-processing mess you’d face with older tools like CoreNLP OpenIE.

---

Would you like me to show you a **real working Docker + FastAPI wrapper example for DeepKE (RE + EE) you can deploy today?**
If yes, just say "**Yes, DeepKE FastAPI.**"
I can also show you how to call it cleanly from **Clojure**.


Perfect.
Here's a **practical, clean setup to run DeepKE (Relation Extraction + Event Extraction) via FastAPI in Docker**.

---

## ✅ Step 1: Prepare the `Dockerfile`

We will create a lightweight Docker container that:

* Installs DeepKE (from source or HuggingFace-supported fork).
* Runs a FastAPI service that receives text and returns relations and events.

```dockerfile
FROM pytorch/pytorch:1.13.1-cuda11.6-cudnn8-runtime

# Install required packages
RUN apt-get update && apt-get install -y git wget python3-pip && rm -rf /var/lib/apt/lists/*

# Install DeepKE (Relation Extraction and Event Extraction modules)
RUN pip install fastapi uvicorn transformers

# Clone DeepKE (you can also use your fork or specific branch)
RUN git clone https://github.com/zjunlp/DeepKE.git /deepke
WORKDIR /deepke
RUN pip install -r requirements.txt
RUN pip install -e .

# Copy our custom FastAPI app
COPY app /app
WORKDIR /app

CMD ["uvicorn", "api:app", "--host", "0.0.0.0", "--port", "8000"]
```

---

## ✅ Step 2: Write the FastAPI wrapper (`app/api.py`)

```python
from fastapi import FastAPI
from pydantic import BaseModel
from deepke.re import Predictor as REPredictor
from deepke.ee import Predictor as EEPredictor

# Initialize FastAPI
app = FastAPI(title="DeepKE Relation & Event Extraction API")

# Load RE and EE models once (for efficiency)
re_predictor = REPredictor('./deepke/config/re/bert', 'bert')
re_predictor.load()
ee_predictor = EEPredictor('./deepke/config/ee/ace2005', 'bert')
ee_predictor.load()

class RequestBody(BaseModel):
    text: str

@app.post("/extract")
def extract(body: RequestBody):
    text = body.text
    # Extract relations
    relations = re_predictor.predict(text)
    # Extract events
    events = ee_predictor.predict(text)
    return {
        "relations": relations,
        "events": events
    }
```

---

## ✅ Step 3: Compose it (`docker-compose.yml`)

```yaml
version: "3"

services:
  deepke-fastapi:
    build: .
    ports:
      - "8000:8000"
    container_name: deepke-fastapi
```

---

## ✅ Step 4: Build and run it

```bash
docker-compose build
docker-compose up -d
```

Test it:

```bash
curl -X POST http://localhost:8000/extract \
  -H "Content-Type: application/json" \
  -d '{"text": "Dr Nandipha Magudumana was deported from Tanzania."}'
```

You should get:

```json
{
  "relations": [
    {"subject": "Dr Nandipha Magudumana", "relation": "deported_from", "object": "Tanzania"}
  ],
  "events": [
    {"type": "Deportation", "trigger": "deported", "arguments": {...}}
  ]
}
```

---

## 🛠 Notes:

* The `Predictor` APIs are available from DeepKE.
* You may need to adjust config paths if you want to use your own models.
* DeepKE supports using HuggingFace pretrained models if you want even **lighter inference with Transformers only**.

---

Would you also like a **Clojure client function to call this FastAPI DeepKE service and parse the triples/events cleanly?**
If yes, just say "**Yes, Clojure client.**"

# Deployment Machines

Good, strategic question.
The **machine requirements** for **DeepKE / SpERT / REBEL / SpaCy RE in Docker** will depend on these key factors:

## 💡 Key Considerations

| Requirement                            | Suggested Specs                                  | Notes                                                         |
| -------------------------------------- | ------------------------------------------------ | ------------------------------------------------------------- |
| **CPU-only basic RE models**           | 4-8 vCPU, 16 GB RAM                              | For small-scale tasks, testing, prototyping                   |
| **GPU inference (fast, large models)** | NVIDIA GPU (e.g. RTX 3060+, A10, T4) + 24 GB RAM | CUDA support needed (DeepKE & SpERT benefit heavily from GPU) |
| **Throughput (concurrent users)**      | Depends on users/requests: 16-32 vCPU, 64 GB RAM | Use Gunicorn workers or FastAPI async for scaling             |
| **Disk space**                         | At least 50 GB (models + logs + temp)            | Transformer models are large (\~1-5 GB each)                  |

---

## ⚙ Recommended Profiles

### 🟢 Light/Proof-of-Concept (CPU only)

* VM or VPS (AWS EC2 t3.large or t4g.large, DigitalOcean 8vCPU droplet)
* 4-8 vCPU, 16-32 GB RAM
* No GPU needed
* Use smaller models (`bert-base-uncased` or `bert-base-chinese`)

### 🟡 Production-ready (GPU acceleration)

* NVIDIA T4, RTX 3060+, A10, A100 (Cloud GPU or on-premise)
* 1 GPU (16-24 GB VRAM), 32-64 GB RAM
* e.g. AWS EC2 g4dn.xlarge, g5.xlarge, Lambda Labs GPU servers
* Docker with `--gpus all`
* You will get **\~5x faster inference, much lower latency**

### 🔵 Heavy production (high concurrency, batch jobs)

* Multi-GPU servers (e.g., 2 x A100, 128 GB RAM)
* Use with FastAPI async workers (Gunicorn/Uvicorn workers)
* Kubernetes + autoscaling for large org deployments

---

## 🚩 Notes on efficiency:

* DeepKE & SpERT are **very GPU-hungry if using large models** (RoBERTa-large, BERT-large).
* If you're sticking to **BERT-base or DistilBERT**, you can get away with **CPU-only for low volume** (but with higher latency \~1-3s per sentence).
* SpaCy RE models can run **lightweight and fast on CPU**, but will be less powerful than DeepKE RE.

---

## 🌐 Cloud Suggestions

| Cloud Provider | Instance Type              | Notes                                         |
| -------------- | -------------------------- | --------------------------------------------- |
| AWS            | `g5.xlarge`, `g4dn.xlarge` | GPU inference, scalable, good for API hosting |
| Google Cloud   | `n1-standard-8` + T4 GPU   | Efficient for inference APIs                  |
| Azure          | `Standard_NC6`             | Older GPU, but works fine for DeepKE          |
| Lambda Labs    | `RTX 3090` or `A6000` VPS  | Budget-friendly, raw GPU power                |
| Local server   | RTX 3060 Ti+, 64 GB RAM    | For self-hosting, lab experiments             |

# Homelab Deployment

> Could I serve this from a home lab? What would the optimal deployment be on a box with 16gb of ram and a core i3?

Absolutely, you can serve **DeepKE / SpaCy RE / lightweight RE models from a home lab**, but let's be realistic about your current **hardware:**

---

## 🎯 Your Current Box:

| Spec     | Reality Check                               |
| -------- | ------------------------------------------- |
| **CPU**  | Core i3 (likely 4 threads, maybe older gen) |
| **RAM**  | 16 GB                                       |
| **GPU**  | Likely none (please confirm)                |
| **Disk** | Enough? (\~50 GB free for models + logs?)   |

---

## 🛠 What you can do safely (and what not)

| Option                                     | Feasibility                         | Notes                                                                                       |
| ------------------------------------------ | ----------------------------------- | ------------------------------------------------------------------------------------------- |
| **SpaCy + RE (CPU-only)**                  | ✅ Good                              | SpaCy transformers run decently on CPU. Use `distilbert-base` or smaller.                   |
| **DeepKE (CPU-only inference)**            | 🟡 OK but slow                      | Will work for low traffic or batch jobs. Expect \~3-5s per sentence latency.                |
| **DeepKE (with large models, GPU needed)** | ❌ Not realistic                     | Your box lacks GPU. Even if you had one, 16 GB RAM might bottleneck depending on the model. |
| **REBEL (CPU-only)**                       | ❌ Very heavy on CPU, slow           | Not suited unless you have patience or very low volume.                                     |
| **OpenNRE (BERT-base models, CPU)**        | ✅ Good for relation extraction only | OpenNRE with `bert-base-uncased` will run on CPU reasonably (still slowish but doable).     |

---

## ✅ Optimal deployment strategy on your box

1. **Use SpaCy + RE models (via FastAPI)**

   * Use **`spacy-transformers`** with smaller models like `distilbert-base-uncased`.
   * Deploy inside a **Docker container running FastAPI (CPU-only)**.
   * Use **Uvicorn async workers**.
   * You will have **\~0.5s-1s latency per sentence**, which is very acceptable.

2. **Optionally add OpenNRE (BERT-base, CPU)**

   * You can set up **OpenNRE Docker** as a sidecar container.
   * Use it for RE tasks if SpaCy isn't enough.

3. **Keep the batch size low**

   * Always process **sentence-by-sentence or small batches**.
   * Avoid overloading your limited threads and memory.

4. **Monitoring & stability**

   * Use **NGINX as a reverse proxy** with rate limits.
   * Monitor RAM usage, keep swap enabled.
   * Use lightweight queueing (e.g. Redis) if you expect spikes.

## ❗ Golden Rule for your home lab

> On CPU-only (especially Core i3), your enemy is latency and memory bottlenecks, not the actual model loading.
>
> Stick to **lightweight models, asynchronous APIs, and low-concurrency.**
> For hobby, personal, or low-traffic RE extraction? ✅ Works fine.
> For high-scale? ❌ Don't even try without GPU.

## ✅ Budget-Friendly GPU Options (Used or New)

| GPU                              | VRAM   | Performance (vs CPU) | Power    | Notes                                                                           |
| -------------------------------- | ------ | -------------------- | -------- | ------------------------------------------------------------------------------- |
| **NVIDIA RTX 2060 / 2060 Super** | 6-8 GB | 10x-20x              | 160-185W | Great used value, supports FP16, enough for inference & light fine-tuning       |
| **NVIDIA RTX 3060 (non-Ti)**     | 12 GB  | 20x-30x              | 170W     | Sweet spot for inference-heavy workloads; huge VRAM for the price               |
| **NVIDIA RTX 2070 Super**        | 8 GB   | 15x-25x              | 215W     | Slightly more power hungry, solid for mixed workloads                           |
| **NVIDIA GTX 1080 Ti (used)**    | 11 GB  | 15x-20x              | 250W     | Solid performer but lacks Tensor cores (slightly less efficient for modern NLP) |

## ❗ Important notes for your **Core i3 + 16 GB RAM setup**

| Thing to watch          | Why                                            | Recommendation                   |
| ----------------------- | ---------------------------------------------- | -------------------------------- |
| **PCIe x16 slot speed** | Older boards might only support PCIe 3.0 x8    | Still fine, but check            |
| **CPU bottleneck risk** | GPU will be waiting on your CPU in heavy tasks | Use async/batching               |
| **Power supply (PSU)**  | Check wattage & connectors                     | Minimum 500W PSU                 |
| **RAM pressure**        | 16 GB is tight for NLP pipelines               | Manage swap, keep processes lean |

---

## 💡 Bonus option for ultra-low power setups

| GPU                                   | VRAM  | Pros                                                             | Cons                                                            |
| ------------------------------------- | ----- | ---------------------------------------------------------------- | --------------------------------------------------------------- |
| **NVIDIA T4 (used data center card)** | 16 GB | Very power efficient, low-profile, 70W, great for inference-only | Needs airflow, PCIe slot only (no monitor output), hard to find |

---

## 💰 Expected Price (used market 2025):

| GPU             | Price (used, fair) |
| --------------- | ------------------ |
| RTX 2060        | \~\$150 USD        |
| RTX 3060 (12GB) | \~\$220-250 USD    |
| T4              | \~\$180-220 USD    |

Would you also like a **ready-made DeepKE + FastAPI Dockerfile optimized for GPU inference**, with a Clojure client to talk to it?
If yes, just say "**Yes, DeepKE GPU Dockerfile + Clojure client.**"

# DeepKE Dockerfile + Clojure Client

> Yes, DeepKE GPU Dockerfile + Clojure client.

🔥 Great. Here's a clean, production-grade example:

---

## 🚀 DeepKE GPU Inference with FastAPI via Docker

### 🐳 Dockerfile (DeepKE + FastAPI + GPU ready)

```Dockerfile
FROM pytorch/pytorch:2.2.2-cuda12.1-cudnn8-runtime

# Install OS-level deps
RUN apt update && apt install -y git python3-pip && rm -rf /var/lib/apt/lists/*

# Install DeepKE and FastAPI
WORKDIR /app
RUN git clone https://github.com/zjunlp/DeepKE.git && \
    cd DeepKE && \
    pip install -r requirements.txt && \
    pip install fastapi uvicorn pydantic

# Optional: preload model (adjust as needed)
RUN python -c "from deepke.re import Trainer; Trainer.from_pretrained('re_tacred_bert_softmax')"

# Copy app
COPY app /app/app

EXPOSE 8000

# Launch FastAPI (adjust DeepKE service call inside the app)
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]
```

---

### 🗂 Example FastAPI App (`app/main.py`)

```python
from fastapi import FastAPI
from pydantic import BaseModel
from deepke.re import Trainer

app = FastAPI()

# Load model at startup
model = Trainer.from_pretrained('re_tacred_bert_softmax')

class InferenceRequest(BaseModel):
    text: str

@app.post("/extract")
def extract_relations(request: InferenceRequest):
    result = model.predict([request.text])
    return {"relations": result}
```

---

## ✅ Example Docker Compose (GPU ready)

```yaml
version: '3.9'
services:
  deepke-gpu:
    build: .
    ports:
      - "8000:8000"
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: all
              capabilities: [gpu]
```

---

## 🛠 Build & Run

```bash
docker-compose build
docker-compose up -d
```

Test:

```bash
curl -X POST http://localhost:8000/extract -H "Content-Type: application/json" -d '{"text": "Apple acquired Beats Electronics for $3 billion."}'
```

---

## 💡 Minimal Clojure Client using `clj-http`

```clojure
(ns deepke-client.core
  (:require [clj-http.client :as client]
            [cheshire.core :as json]))

(defn extract-relations [text]
  (let [response (client/post "http://localhost:8000/extract"
                              {:headers {"Content-Type" "application/json"}
                               :body (json/generate-string {:text text})
                               :as :json})]
    (:body response)))

;; Example
(println (extract-relations "Dr Nandipha Magudumana was deported from Tanzania."))
```

---

## 🧪 Notes

* The example uses **DeepKE's RE (Relation Extraction) pretrained model**, but DeepKE also supports **NER, event extraction**, etc. Adjust `Trainer.from_pretrained(...)` accordingly.
* GPU acceleration works automatically inside the container (`torch.cuda.is_available()` will return `True`).
* This setup is clean, portable, and ready for **local LAN, cloud, or internal API consumption**.

---

Would you also like me to show how to **switch the model to event extraction or NER, and make the Clojure client support multiple modes?**
If yes, say "**Yes, multi-mode DeepKE API + Clojure client.**"

🔥 Here’s how to build a **multi-mode DeepKE FastAPI service + Clojure client**.

---

## 🚀 Multi-Mode DeepKE FastAPI (Relation, Event, NER in one API)

### Updated `app/main.py`

```python
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
from deepke.re import Trainer as RE_Trainer
from deepke.ner import Trainer as NER_Trainer
from deepke.event import Trainer as Event_Trainer

app = FastAPI()

# Load models once at startup (choose your models)
re_model = RE_Trainer.from_pretrained('re_tacred_bert_softmax')
ner_model = NER_Trainer.from_pretrained('ner_conll03_bert')
event_model = Event_Trainer.from_pretrained('event_eventbert')

class InferenceRequest(BaseModel):
    text: str
    task: str  # 'relation', 'ner', or 'event'

@app.post("/extract")
def extract(request: InferenceRequest):
    if request.task == 'relation':
        result = re_model.predict([request.text])
    elif request.task == 'ner':
        result = ner_model.predict([request.text])
    elif request.task == 'event':
        result = event_model.predict([request.text])
    else:
        raise HTTPException(status_code=400, detail="Unknown task. Use 'relation', 'ner', or 'event'.")
    return {"result": result}
```

---

## 🧪 Docker Compose (unchanged)

Same as before:

```yaml
version: '3.9'
services:
  deepke-gpu:
    build: .
    ports:
      - "8000:8000"
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: all
              capabilities: [gpu]
```

---

## ✅ Build & Run

```bash
docker-compose build
docker-compose up -d
```

---

## 💡 Clojure Multi-Task Client (`deepke-client.core`)

```clojure
(ns deepke-client.core
  (:require [clj-http.client :as client]
            [cheshire.core :as json]))

(defn extract [text task]
  (let [response (client/post "http://localhost:8000/extract"
                              {:headers {"Content-Type" "application/json"}
                               :body (json/generate-string {:text text :task task})
                               :as :json})]
    (:body response)))

;; Example Usage:
(println "Relation Extraction:")
(println (extract "Apple acquired Beats Electronics for $3 billion." "relation"))

(println "\nNamed Entity Recognition:")
(println (extract "Barack Obama was born in Hawaii." "ner"))

(println "\nEvent Extraction:")
(println (extract "Nandipha Magudumana was arrested in Tanzania." "event"))
```

---

## 🛠 Notes

| Task     | Trainer        | Example Output (DeepKE format)            |
| -------- | -------------- | ----------------------------------------- |
| relation | RE\_Trainer    | \[{"head": "...", "relation": "..."}]     |
| ner      | NER\_Trainer   | \[{"entity": "...", "type": "..."}]       |
| event    | Event\_Trainer | \[{"trigger": "...", "event\_type": ...}] |

* You can add validation, result formatting, or merge predictions in FastAPI later.
* Clojure client stays simple and only switches the `task` string.
* You can easily swap to other models by changing the `.from_pretrained()`.

---

## ⚡ Recommendation for your i3 + 16GB RAM + mid-tier GPU (e.g. RTX 3060):

* **Use lightweight containers like above.**
* **No Kubernetes needed.**
* **Monitor GPU temps + VRAM usage (via NVIDIA exporter).**
* **Optimize FastAPI worker count (e.g. `--workers 2` if your CPU is weak).**
* **Use LAN reverse proxy with Caddy.**

---

Would you also like a **fully pre-built Ansible playbook to set up the entire DeepKE + GPU Docker stack + monitoring on Ubuntu 22.04 headless?**
If yes, just say
`Yes, Ansible home lab playbook.`
# Multiple Computers

Absolutely! You can absolutely use multiple computers for this homelab setup, and it’s actually a great idea to distribute the workload, especially with resource-heavy tasks like DeepKE’s GPU inference and monitoring.

---

### How to do it — Multi-Node Homelab with Docker:

#### 1. **Separate Roles by Machines**

| Machine Role                    | Example Tasks                                  | Why                                |
| ------------------------------- | ---------------------------------------------- | ---------------------------------- |
| **GPU Server**                  | Run DeepKE GPU container + model inference     | Heavy GPU usage, isolate workload  |
| **Reverse Proxy + API Gateway** | Run Caddy or Traefik for routing               | Manage HTTPS, route requests       |
| **Monitoring Node**             | Run NVIDIA exporter + Prometheus + Grafana     | Centralize metrics collection      |
| **Client/Dev Machine**          | Run your Clojure client or other API consumers | Lightweight, local dev environment |

---

#### 2. **Networking**

* Use a **private network** (VLAN or VPN) so containers across machines can talk.
* You can create a **Docker Swarm** cluster or **Kubernetes** if you want orchestration.
* Or use **simple static IPs/DNS** + configure Caddy on your gateway node to route requests between nodes.

---

#### 3. **Example Deployment Architecture**

```
[ GPU Server ] -----------[ Monitoring Server ]------------[ Client Machine ]
     |                             |                              |
Docker: deepke-gpu            Docker: nvidia-exporter,         Your code runs here,
                             prometheus, grafana             sends requests to API

           \                                              /
            \--------------------------------------------/
                         Private Docker Network or VPN
```

---

#### 4. **How to share API endpoints**

* On the gateway machine running **Caddy**, configure reverse proxy rules pointing to the GPU server IP/port.
* Or use a **load balancer** if you have multiple GPU nodes.

Example Caddy snippet routing requests:

```caddyfile
deepke.mylab.local {
    reverse_proxy gpu-server.local:8000
}

metrics.mylab.local {
    reverse_proxy monitoring-server.local:9400
}
```

---

#### 5. **Notes**

* The GPU server needs the Nvidia drivers + Docker Nvidia runtime installed.
* Monitoring and proxy servers don’t need GPUs, so can run on low-power machines.
* You can horizontally scale DeepKE by deploying multiple GPU servers behind a load balancer.
* Secure your network and API endpoints, especially if you expose outside your LAN.

---

### TL;DR

* Yes, split services across multiple machines for performance and management.
* Use Docker networking or orchestration (Docker Swarm, Kubernetes) to connect containers.
* Use a reverse proxy on a gateway machine to unify access.
* Assign roles: GPU-heavy, proxy, monitoring, and client machines separately.

---

If you want, I can help you draft a **multi-node Docker Swarm config** or **Kubernetes manifests** for this!
Just say: "**Yes, multi-node orchestration config.**"

# Multi-Machine Networking

> Would it be smartest to network traditionally or to use OpenShift/Kubernetes/Docker Swarm for this?

Great question! The choice between traditional networking (simple Docker + manual networking) versus container orchestration platforms like **Kubernetes**, **OpenShift**, or **Docker Swarm** depends on your homelab goals, scale, and how much complexity you want to manage.

---

### Traditional Networking (Docker Compose + manual IP/DNS)

**Pros:**

* **Simple to set up and maintain** — especially for 2-3 nodes.
* Low overhead — less CPU/memory consumed by orchestration agents.
* Easier to troubleshoot for smaller setups.
* Perfect for stable, static environments where you control the nodes.

**Cons:**

* No built-in service discovery or automatic failover.
* Manual management of container restarts, scaling, and networking.
* Harder to scale beyond a few machines.

**Best for:** Small home labs, fewer machines, mostly static workloads.

---

### Docker Swarm

**Pros:**

* Built into Docker CLI — no extra tools needed.
* Easier learning curve than Kubernetes.
* Simple service discovery and scaling.
* Good for small to medium clusters (\~up to a dozen nodes).
* Supports multi-host networking automatically.

**Cons:**

* Less ecosystem and community support than Kubernetes.
* Less powerful for complex deployments.
* Less flexible than Kubernetes/OpenShift.

**Best for:** Small to medium homelabs wanting lightweight orchestration.

---

### Kubernetes (or OpenShift)

**Pros:**

* Industry standard for container orchestration.
* Highly scalable and flexible.
* Rich ecosystem: monitoring, logging, CI/CD integrations.
* Automated scaling, rolling updates, self-healing.
* OpenShift adds enterprise features on top of Kubernetes.

**Cons:**

* Higher complexity and learning curve.
* More resource overhead — your homelab machines need to be beefy enough.
* More complex setup and maintenance.
* Might be overkill for small personal projects.

**Best for:** Larger homelabs, experimentation with cloud-native tech, future-proofing.

---

### What I’d recommend for your homelab (16GB RAM, Core i3, a few nodes)

* If you want **simplicity and quick deployment**, go **traditional networking** with Docker Compose + manual IP/DNS or a lightweight reverse proxy.
* If you want **some orchestration but still easy setup**, try **Docker Swarm** — good balance of features and simplicity.
* If you want to **invest in learning Kubernetes/OpenShift** and plan to scale or run many services, go for it — but expect a steeper setup curve.

---

### Summary table

| Option               | Complexity | Scalability | Overhead | Best use case                      |
| -------------------- | ---------- | ----------- | -------- | ---------------------------------- |
| Traditional Docker   | Low        | Low         | Low      | Small, stable homelabs             |
| Docker Swarm         | Medium     | Medium      | Medium   | Small to medium clusters           |
| Kubernetes/OpenShift | High       | High        | High     | Large clusters, advanced use cases |

If you want, I can help you set up a **Docker Swarm multi-node cluster** for DeepKE and monitoring — easy and effective for your hardware specs.
Just say: "**Yes, Docker Swarm multi-node setup please.**"

# Docker Swarm Multi-Node Setup

Great! Here’s a step-by-step guide to set up a **Docker Swarm multi-node cluster** for your homelab running DeepKE (or similar containers). This will cover:

* Initializing the swarm
* Adding worker nodes
* Deploying services with a simple `docker-compose.yml`
* Networking considerations
* Basic monitoring

---

## Step 1: Prepare your machines

* Make sure Docker is installed on **all nodes** (manager + workers).
* All nodes should be on the same network and able to communicate over ports **2377 (Swarm management)**, **7946 (container network discovery)**, **4789 (overlay network VXLAN)**.
* On your GPU machine(s), install Nvidia drivers and Docker Nvidia runtime if you want GPU acceleration.

---

## Step 2: Initialize Docker Swarm on manager node

SSH to the machine you want as the **manager** (say, your main GPU box):

```bash
docker swarm init --advertise-addr <MANAGER_IP>
```

* `<MANAGER_IP>` is the IP reachable by all other nodes on your LAN.

This command outputs a join token command, something like:

```bash
docker swarm join --token SWMTKN-1-xxx-xxx <MANAGER_IP>:2377
```

---

## Step 3: Join worker nodes

On every other machine (workers), run the join command from above:

```bash
docker swarm join --token SWMTKN-1-xxx-xxx <MANAGER_IP>:2377
```

---

## Step 4: Verify the cluster

Back on the manager node, run:

```bash
docker node ls
```

You should see all nodes listed with status `Ready`.

---

## Step 5: Create your `docker-compose.yml` for DeepKE + monitoring

Example `docker-compose.yml` adapted for swarm (use `deploy` section):

```yaml
version: "3.8"

services:

  deepke:
    image: your-deepke-gpu-image:latest
    deploy:
      replicas: 1
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
      restart_policy:
        condition: on-failure
    environment:
      - NVIDIA_VISIBLE_DEVICES=all
    runtime: nvidia
    ports:
      - "8000:8000"     # API port
    networks:
      - deepke-net

  prometheus:
    image: prom/prometheus:latest
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
    ports:
      - "9090:9090"
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    networks:
      - deepke-net

  grafana:
    image: grafana/grafana:latest
    ports:
      - "3000:3000"
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    networks:
      - deepke-net

networks:
  deepke-net:
    driver: overlay
```

* Put your Prometheus config (`prometheus.yml`) in the same folder.
* This setup creates an overlay network so containers on different hosts can talk.

---

## Step 6: Deploy the stack

On your manager node:

```bash
docker stack deploy -c docker-compose.yml deepke-stack
```

Check services:

```bash
docker service ls
```

---

## Step 7: Access services

* DeepKE API: `http://<MANAGER_IP>:8000`
* Prometheus UI: `http://<MANAGER_IP>:9090`
* Grafana UI: `http://<MANAGER_IP>:3000`

---

## Step 8: Optional: Add reverse proxy (Caddy/Traefik) on manager or gateway node

You can set up Caddy or Traefik container to proxy and secure your APIs with HTTPS and route multiple services.

---

## Notes & Tips

* Use labels and placement constraints if you want to pin DeepKE service only to GPU nodes. Example:

```yaml
deploy:
  placement:
    constraints:
      - node.labels.gpu==true
```

Set node label on manager:

```bash
docker node update --label-add gpu=true <NODE-ID>
```

* For advanced GPU scheduling, check Nvidia Docker + Swarm docs.

---

If you want, I can help you write the Prometheus config or Caddy reverse proxy too.
Just say the word!

# Prometheus and Grafana Config

Absolutely! Here are simple starter configs for **Prometheus** and **Grafana** tailored to monitor your Docker Swarm services like DeepKE.

---

## Prometheus Config (`prometheus.yml`)

This config tells Prometheus to scrape metrics exposed by your services. If your services don’t expose Prometheus metrics natively, you can add exporters or enable metrics endpoints first.

```yaml
global:
  scrape_interval: 15s
  evaluation_interval: 15s

scrape_configs:
  # Scrape Docker Swarm nodes using cAdvisor (if you deploy it)
  - job_name: 'cadvisor'
    static_configs:
      - targets: ['cadvisor:8080']

  # Scrape Docker Swarm services with metrics endpoint
  - job_name: 'deepke'
    static_configs:
      - targets: ['deepke:8000']

  # Docker Engine metrics (optional, via docker daemon or node-exporter)
  - job_name: 'docker-engine'
    static_configs:
      - targets: ['docker-host1:9323', 'docker-host2:9323']
```

### Notes:

* You need to run **cAdvisor** or similar exporter to get container-level metrics.
* Your DeepKE API container must expose Prometheus metrics at the specified port (`8000` here is the example API port). If DeepKE doesn’t expose Prometheus metrics, consider adding a Prometheus exporter sidecar or using a generic exporter.
* Replace `docker-host1`, `docker-host2` with your actual node IPs and make sure the endpoints are reachable.

---

## Simple cAdvisor Service (optional for container metrics)

Add this to your `docker-compose.yml` for monitoring:

```yaml
  cadvisor:
    image: gcr.io/cadvisor/cadvisor:v0.47.0
    ports:
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    networks:
      - deepke-net
```

---

## Grafana Setup

Grafana config is mostly UI-driven but here’s what you do after launching Grafana (`http://<MANAGER_IP>:3000`):

1. **Login** (default: admin/admin) and change password.
2. **Add Data Source**:

   * Choose **Prometheus**
   * URL: `http://prometheus:9090` (Docker service name inside the overlay network)
3. **Import Dashboard**:

   * Go to **Dashboards > Manage > Import**
   * Use a pre-built dashboard ID from [Grafana Dashboards](https://grafana.com/grafana/dashboards/) for Docker or cAdvisor, e.g. dashboard ID **893** (Docker monitoring).
   * Or build your own with metrics like container CPU, memory, network.

---

## Summary

* Prometheus scrapes metrics (needs your services to expose or run exporters).
* cAdvisor can give you container-level metrics automatically.
* Grafana connects to Prometheus, visualize metrics, and create alerts.

---

If you want, I can generate a full sample **docker-compose.yml** with cAdvisor + Prometheus + Grafana plus a simple exporter for your DeepKE API in Clojure to expose metrics — just ask!

# DeepKE Prometheus Metrics

Sure! Here’s a **full example `docker-compose.yml`** that sets up:

* **DeepKE API** (simulated here with a basic example app exposing Prometheus metrics)
* **cAdvisor** for container metrics
* **Prometheus** to scrape metrics from DeepKE and cAdvisor
* **Grafana** for dashboards and visualization

---

### `docker-compose.yml`

```yaml
version: "3.8"

services:

  deepke:
    image: your-deepke-gpu-image:latest
    deploy:
      replicas: 1
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
      restart_policy:
        condition: on-failure
    environment:
      - NVIDIA_VISIBLE_DEVICES=all
    runtime: nvidia
    ports:
      - "8000:8000"     # DeepKE API port
    networks:
      - monitoring-net

  # A simple Prometheus metrics exporter for DeepKE API.
  # If your actual DeepKE exposes /metrics, you can skip this service.
  deepke-exporter:
    image: your-deepke-exporter:latest
    depends_on:
      - deepke
    ports:
      - "9100:9100"
    networks:
      - monitoring-net

  cadvisor:
    image: gcr.io/cadvisor/cadvisor:v0.47.0
    ports:
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    networks:
      - monitoring-net

  prometheus:
    image: prom/prometheus:latest
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
    ports:
      - "9090:9090"
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    networks:
      - monitoring-net

  grafana:
    image: grafana/grafana:latest
    ports:
      - "3000:3000"
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    networks:
      - monitoring-net

networks:
  monitoring-net:
    driver: overlay
```

---

### `prometheus.yml`

```yaml
global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'cadvisor'
    static_configs:
      - targets: ['cadvisor:8080']

  - job_name: 'deepke-exporter'
    static_configs:
      - targets: ['deepke-exporter:9100']
```

---

### Notes:

* Replace `your-deepke-gpu-image:latest` with your actual DeepKE GPU-enabled Docker image.
* `deepke-exporter` is a **placeholder** for a simple Prometheus exporter container. If your DeepKE API **already exposes `/metrics`**, you can expose that port directly and update Prometheus to scrape it, skipping this exporter service.
* All services share the `monitoring-net` overlay network so they can talk via service name.
* `cadvisor` scrapes Docker metrics from the host(s).
* `prometheus` scrapes `cadvisor` and `deepke-exporter`.
* `grafana` connects to Prometheus at `http://prometheus:9090` when you set up the data source in the UI.

---

### Simple DeepKE Prometheus Exporter (Clojure example snippet)

If you want a minimal Prometheus endpoint in your DeepKE app (using `io.prometheus/simpleclient`):

```clojure
(ns deepke.metrics
  (:require [ring.adapter.jetty :refer [run-jetty]]
            [ring.util.response :refer [response]]
            [io.prometheus.simpleclient :as prom]))

(def registry (prom/collector-registry))

(def request-counter (prom/counter "deepke_requests_total" "Total API requests" [] registry))

(defn metrics-handler [_request]
  (response (prom/format-metrics registry)))

(defn wrap-count-requests [handler]
  (fn [req]
    (prom/inc! request-counter)
    (handler req)))

(defn -main []
  (run-jetty (-> your-app-handler
                 wrap-count-requests
                 (assoc :metrics metrics-handler))
             {:port 8000}))
```

# Including an LLM in the Environment

Absolutely! To **deploy a small LLM alongside your DeepKE + monitoring stack**, you can add a lightweight LLM server container that exposes an HTTP API, and hook it into the same Docker Compose setup.

---

## How to add a small LLM to your stack

### 1. Pick a lightweight LLM serving option

Here are some popular lightweight LLM frameworks you can run easily on a home lab or modest GPU:

* **[llama.cpp](https://github.com/ggerganov/llama.cpp)**: CPU-optimized, very lightweight local LLM (7B, 13B).
* **[Text Generation Inference](https://github.com/huggingface/text-generation-inference)** by Hugging Face: runs Hugging Face models with efficient GPU acceleration, supports small models.
* **[FastChat](https://github.com/lm-sys/FastChat)**: for chat models, includes server.
* **[GPT4All](https://github.com/nomic-ai/gpt4all)**: small models with API serving capabilities.

---

### 2. Example: Deploy `llama.cpp` HTTP server container

There are existing Docker containers for llama.cpp that serve a REST API.

One example: [`ghcr.io/corazzon/llama-cpp-python`](https://github.com/abetlen/llama-cpp-python) provides a simple FastAPI server wrapping llama.cpp.

---

### 3. Update your `docker-compose.yml` to include the LLM service

Here is an **extended snippet** with a llama.cpp-based LLM server added:

```yaml
version: "3.8"

services:
  deepke:
    image: your-deepke-gpu-image:latest
    runtime: nvidia
    environment:
      - NVIDIA_VISIBLE_DEVICES=all
    ports:
      - "8000:8000"
    networks:
      - monitoring-net

  deepke-exporter:
    image: your-deepke-exporter:latest
    depends_on:
      - deepke
    ports:
      - "9100:9100"
    networks:
      - monitoring-net

  cadvisor:
    image: gcr.io/cadvisor/cadvisor:v0.47.0
    ports:
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
    networks:
      - monitoring-net

  prometheus:
    image: prom/prometheus:latest
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
    ports:
      - "9090:9090"
    networks:
      - monitoring-net

  grafana:
    image: grafana/grafana:latest
    ports:
      - "3000:3000"
    networks:
      - monitoring-net

  llama-cpp:
    image: ghcr.io/corazzon/llama-cpp-python:latest
    command: >
      --model /models/ggml-model-q4_0.bin
      --host 0.0.0.0
      --port 5000
    volumes:
      - ./models:/models
    ports:
      - "5000:5000"
    networks:
      - monitoring-net

networks:
  monitoring-net:
    driver: overlay
```

---

### 4. How to use this

* Put your quantized llama model (e.g. `ggml-model-q4_0.bin`) in the local folder `./models`
* The LLM HTTP API will be available on port `5000` of the host.
* You can call it from your other services (or your client apps) via `http://llama-cpp:5000` inside the Docker network.

---

### 5. Optionally: Add LLM metrics for Prometheus

If the LLM server exposes metrics, add a scrape job in `prometheus.yml`:

```yaml
scrape_configs:
  - job_name: 'llama-cpp'
    static_configs:
      - targets: ['llama-cpp:5000']  # Adjust if metrics port differs
```

---

### 6. Minimal LLM API example request

You can POST a prompt like:

```bash
curl -X POST "http://localhost:5000/v1/completions" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"Explain Docker Swarm in simple terms.","max_tokens":50}'
```

---

## Summary

* Add a lightweight LLM container like `llama-cpp-python` to your Docker Compose.
* Make sure the model file is accessible (via mounted volume).
* Use the LLM HTTP API inside your Docker network for inference.
* Extend Prometheus to scrape metrics if available.

---

If you want, I can help you:

* Set up a simple client in Clojure to call the LLM API.
* Show how to link LLM responses with DeepKE extracted triples for enriched NLP workflows.
* Build a monitoring dashboard in Grafana combining DeepKE + LLM metrics.

Just ask!

# Replacing Gemini

> Yes, show me how to deploy a small GPU-enabled LLM to replace Gemini free in this environment please?

Got it! To replace Gemini Free with a **small GPU-enabled LLM** in your existing Docker Compose environment (with Prometheus, Grafana, DeepKE, etc.), here’s a practical step-by-step guide using **Hugging Face’s `text-generation-inference` (TGI)** server, which supports GPU acceleration out-of-the-box and is fairly lightweight for smaller models.

---

# Step 1: Hardware & Prerequisites

* NVIDIA GPU with CUDA support (e.g., RTX 3060 or better recommended)
* NVIDIA drivers + CUDA toolkit installed on host
* NVIDIA Container Toolkit installed (`nvidia-docker2`)
* Docker version ≥ 19.03

---

# Step 2: Prepare your model

Choose a small LLM compatible with TGI, e.g., `tiiuae/falcon-7b-instruct` or any smaller model from HF Hub.

Download or mount the model in your host’s `./models` directory:

```bash
mkdir -p ./models
# Optionally use `git lfs` or huggingface CLI to download the model
```

---

# Step 3: Add `llm` service to your `docker-compose.yml`

```yaml
version: '3.8'

services:
  # Your existing services here: cadvisor, prometheus, grafana, deepke...

  llm:
    image: ghcr.io/huggingface/text-generation-inference:latest-gpu
    runtime: nvidia
    environment:
      - NVIDIA_VISIBLE_DEVICES=0  # Use GPU 0
    volumes:
      - ./models:/models
    command: >
      --model /models/falcon-7b-instruct
      --port 5000
      --trust-remote-code
    ports:
      - "5000:5000"
    networks:
      - monitoring-net

networks:
  monitoring-net:
    external: true
```

---

# Step 4: Notes on the Compose config

* `runtime: nvidia` + `NVIDIA_VISIBLE_DEVICES=0` enables GPU passthrough.
* `--trust-remote-code` needed for some models with custom code.
* Expose port 5000 (adjust as needed).
* Assumes `monitoring-net` is your existing overlay network.
* Make sure `./models/falcon-7b-instruct` contains your model files.

---

# Step 5: Launch & verify

```bash
docker-compose up -d llm
docker logs -f <llm_container_id>
```

Look for:

```
INFO:     Started server process [pid]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:5000
```

---

# Step 6: Test the LLM endpoint

Example using `curl`:

```bash
curl -X POST http://localhost:5000/generate -H "Content-Type: application/json" -d '{
  "inputs": "What is the meaning of life?",
  "parameters": {
    "max_new_tokens": 50
  }
}'
```

Response will be a JSON with generated text.

---

# Step 7: Integrate with your Clojure client or API stack

Use this endpoint as your new LLM service, replacing Gemini Free. The API is RESTful and documented [here](https://github.com/huggingface/text-generation-inference#api).

---

# Optional: Resource optimization

* For your 16GB RAM + mid-tier GPU home lab, Falcon 7B may be a bit heavy but can work with mixed precision.
* Alternatively, pick a smaller model like `EleutherAI/gpt-neo-125m` or `facebook/opt-1.3b` to reduce resource load.
* Monitor GPU/CPU usage with your existing Prometheus + cAdvisor stack.

---

# Summary

* Use Hugging Face’s `text-generation-inference` GPU Docker image.
* Deploy with GPU support via Docker Compose (`runtime: nvidia`).
* Mount a small HF model and expose port 5000.
* Replace Gemini free with this endpoint in your app.

---

If you want, I can also help you with Clojure client code to query this new LLM endpoint!

Great question! Running a reasonably powerful LLM **at home** for **inference** and **Retrieval-Augmented Generation (RAG)** means balancing hardware cost, power, and responsiveness.

Here’s a breakdown of what you’d ideally want:

---

## 1. **GPU**

* **Minimum:** NVIDIA RTX 3060 (12GB VRAM)

  * Can handle models like Falcon 7B (quantized, mixed precision).
  * Good for moderate batch sizes and latency.

* **Recommended:** NVIDIA RTX 4080 or RTX 3090/3090 Ti (16–24GB VRAM)

  * Supports larger models (13B+ or even 33B with quantization).
  * Faster inference, multi-user capacity.
  * Better for production-grade RAG pipelines.

* **Why GPU?**
  LLM inference and embedding generation for RAG are heavy on matrix multiplications; GPUs massively speed this up.

---

## 2. **CPU**

* A modern **6-8 core** CPU (e.g., AMD Ryzen 5/7 or Intel i5/i7)

  * Manages data preprocessing, retrieval, orchestrating pipelines.
  * A bottleneck if too weak, but less critical than GPU for inference.

---

## 3. **RAM**

* **Minimum:** 32 GB RAM

  * Loading models, caching embeddings, running retrieval indices.

* **Recommended:** 64 GB RAM+

  * Smooth multitasking, handling larger indices (e.g., FAISS or other vector stores).
  * Run multiple services simultaneously (RAG + embedding generation + API servers).

---

## 4. **Storage**

* Fast NVMe SSD (1 TB+)

  * Quick loading of models (several GB each).
  * Fast retrieval index reads and writes.
  * OS, logs, and datasets.

---

## 5. **Network**

* Gigabit Ethernet or fast Wi-Fi for LAN communication between services/nodes.
* Optional: setup a mini cluster for distributed inference or multi-node RAG.

---

## 6. **Software Setup**

* Linux-based OS (Ubuntu 22.04 LTS preferred) with NVIDIA drivers + CUDA + Docker + NVIDIA Container Toolkit.
* Containerized model serving (e.g., Hugging Face TGI, DeepKE, or custom).
* Vector search engine (FAISS, Milvus) for RAG.

## Final Thoughts

* **Bigger GPU VRAM = bigger models / faster inference / more users.**
* **RAM affects retrieval & embedding workflows more than inference itself.**
* RAG needs both fast vector search and quick LLM calls—optimize both.
