๐Ÿ†˜ Troubleshooting & FAQ

โ“ Frequently Asked Questions

Q: Can I use this with my own LLM models?

Yes! The system supports custom LLM integrations. You can extend the rag_chain.py to integrate with local models like Ollama, or cloud models like AWS Bedrock.

from langchain.llms import YourCustomLLM
# Add your custom LLM integration
Q: How do I process documents in languages other than English?

The system supports multilingual documents. Use multilingual embedding models:

EMBEDDING_MODEL=paraphrase-multilingual-mpnet-base-v2
Q: Can I deploy this in my enterprise environment?

Absolutely! The system supports enterprise deployment with Docker, Kubernetes, and cloud platforms. Check our Deployment Guide for detailed instructions.

Q: What's the maximum number of documents I can process?

There's no hard limit. The system has been tested with 100,000+ documents. Performance depends on your hardware and configuration.

Q: How accurate is the table extraction from PDFs?

The system achieves 90-95% accuracy by using multiple extraction methods (pdfplumber, camelot, tabula) and selecting the best results. Complex tables with merged cells or unusual formatting may have lower accuracy.

# Test PDF processing capabilities
python test_pdf_multimodal.py
Q: Can the system extract images and charts from PDFs?

Yes! The system extracts images using PyMuPDF and analyzes them with AI models for:

  • Image captioning and description
  • OCR text extraction
  • Object detection
  • Chart and diagram analysis

All extracted content becomes searchable through the RAG system.

Q: What types of tables can be extracted?

The system handles various table types:

  • Simple bordered tables
  • Complex multi-page tables
  • Financial reports with merged cells
  • Academic tables with statistical data
  • Tables with mixed data types (text, numbers, dates)

Confidence scores help you identify extraction quality.

๐Ÿ”ง Common Issues & Solutions

Issue Symptoms Solution
PDF Processing Fails "Advanced PDF processing failed" Install missing dependencies: pip install pdfplumber camelot-py[cv] PyMuPDF
Table Extraction Issues No tables found in PDFs Check PDF quality, try different extraction methods, verify table structure
Image Processing Errors Images not extracted Install AI dependencies: pip install transformers torch
API Key Error "No API key found" Verify .env file and API key format
Memory Issues App crashes/slow performance Reduce CHUNK_SIZE or increase system RAM (8GB+ recommended)
Upload Failures "Failed to load documents" Check file format, size limits, and permissions
Slow PDF Processing Long wait times for PDFs Enable only needed extractors, use fast mode, upgrade hardware
No Multimodal Results Missing table/image content Verify multimodal processing is enabled in settings

๐Ÿšจ Quick Fixes

# Test PDF processing capabilities
python test_pdf_multimodal.py

# Install missing PDF dependencies
pip install pdfplumber camelot-py[cv] PyMuPDF tabula-py

# Install AI processing dependencies
pip install transformers torch accelerate

# Clear vector store (if corrupted)
rm -rf vector_store/

# Reset configuration
cp .env.example .env

# Update all dependencies
pip install -r requirements.txt --upgrade

# Check system resources (8GB+ RAM recommended for PDFs)
python -c "import psutil; print(f'RAM: {psutil.virtual_memory().percent}%')"

# Verify PDF processing capabilities
python -c "
try:
    import pdfplumber, camelot, fitz, tabula
    print('โœ… All PDF processing libraries available')
except ImportError as e:
    print(f'โŒ Missing library: {e}')
