Installation & Setup 🛠️

System Requirements:

• NVIDIA GPU (≥16GB VRAM)
• CUDA 12.1+
• Ubuntu 22.04 LTS

Step-by-Step:

# 1. Clone repo
git clone https://github.com/yourorg/etherpdf.git && cd etherpdf

# 2. Create virtual env
python -m venv .env && source .env/bin/activate

# 3. Install core dependencies
pip install -r requirements.txt

# 4. Install CUDA extras
pip install torch==2.1.0+cu121 -f https://download.pytorch.org/whl/torch_stable.html

# 5. Verify installation
python -c "import torch; print(torch.cuda.is_available())"

Deployment Strategies 🚀

Option 1: Docker (Production)

# Dockerfile
FROM nvidia/cuda:12.1.0-base
RUN apt-get update && apt-get install -y python3.10
COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt
CMD ["python", "app.py"]

docker build -t etherpdf .
docker run -p 7860:7860 --gpus all etherpdf

Option 2: Hugging Face Spaces

# README.md header
---
tags: [spaces, document-intelligence]
extra_gpu_tags: true
vram: 16GB
---

Option 3: Kubernetes

# deployment.yaml
apiVersion: apps/v1
kind: Deployment
spec:
  containers:
  - name: etherpdf
    image: etherpdf:latest
    resources:
      limits:

Security Considerations 🔒

1. Data Flow

   sequenceDiagram
       User->>+Server: Upload (Encrypted HTTPS)
       Server->>GPU: Process (Ephemeral Storage)
       GPU->>Server: Structured Data
       Server->>User: Response
       Server->>DB: Log Metadata*

2. Key Measures:

   • File sanitization with python-magic MIME validation
   • CUDA memory isolation between sessions
   • Automatic temp file purging (5min TTL)
   • Dependency scanning via safety check

Sample Documents & Outputs 📑

Input Document:

Output Structure:

{
  "personnel": {
    "name": "John Doe",
    "position": "Offshore Engineer",
    "contractor_status": true,
    "noc_id": "XGTH-2345"
  },
  "activities": {
    "onshore_days": 12,

Troubleshooting 🩺

Common Issues:

1. CUDA Out of Memory

   export PYTORCH_CUDA_ALLOC_CONF=max_split_size_mb:128

2. PDF Rendering Artifacts

   fitz.TOOLS.set_small_glyph_heights(True)  # Before processing

3. Model Loading Errors

   huggingface-cli delete-cache
