Appendix B: Troubleshooting Guide

This section provides solutions to common issues and errors you might encounter during the setup and operation of your AI chatbot. Use these solutions to troubleshoot and resolve problems quickly.

Solutions to Common Issues and Errors

1. NVIDIA Driver Issues:
   • Problem: NVIDIA driver installation fails.

   • Solution: Ensure you have added the correct PPA repository and your system is updated. Reinstall the drivers:

     sudo apt-get purge nvidia*
     sudo add-apt-repository ppa:graphics-drivers/ppa
     sudo apt-get update
     sudo apt-get install nvidia-driver-460
     sudo reboot
     

2. CUDA/cuDNN Installation Issues:
   • Problem: CUDA/cuDNN installation fails or the GPU is not recognized.
   • Solution: Verify compatibility between CUDA, cuDNN, and your NVIDIA driver. Follow the official installation guide and check for any missing steps.
3. Virtual Environment Activation Fails:
   • Problem: The virtual environment does not activate.
   • Solution: Ensure you are using the correct command and path. Check for typos and ensure you have installed python3-venv.
4. Package Installation Errors:
   • Problem: Python package installation fails.

   • Solution: Ensure you have an active internet connection and the correct permissions. Try updating pip and reinstalling the packages:

     pip install --upgrade pip
     pip install -r requirements.txt
     

5. Docker Container Fails to Start:
   • Problem: Docker container fails to start or crashes.
   • Solution: Check the Dockerfile for errors, ensure all dependencies are included, and review the container logs for specific error messages.
6. Chatbot Does Not Respond Correctly:
   • Problem: The chatbot does not respond or provides incorrect responses.
   • Solution: Verify the intent recognition model and training data. Ensure the model is loaded correctly and retrain if necessary.
