Summary

Improve error message when model path does not exist to provide clearer guidance to users.

Changes

  • Enhanced the ValueError message in llama.py to include actionable guidance
  • Added suggestion to verify path correctness and GGUF file accessibility

  • No new dependencies added
  • Error message is clear and actionable
  • Change is minimal and focused
