Hi Anil1872,

Thanks for your post! I noticed you closed this discussion as a duplicate—hopefully your issue was resolved elsewhere. However, for future reference and for others who might encounter a similar situation:

Your error ('/usr/bin/clang++' failed with exit code 1 and Failed building wheel for chroma-hnswlib) typically means that the chroma-hnswlib package requires native compilation and your system is missing required build tools (like a C++ compiler).

Troubleshooting steps you can try:

1. Install development build tools and Python headers for your OS.
   • Ubuntu/Debian:
     sudo apt-get update && sudo apt-get install build-essential python3-dev
   • macOS:
     xcode-select --install
   • Windows:
     Install Visual C++ Build Tools
2. Try installing chroma-hnswlib directly with pip install chroma-hnswlib to catch any additional errors.
3. If you're still stuck, you can:
   • Remove/comment out chroma-hnswlib from requirements.txt, install other dependencies, then install it separately once build tools are ready.
   • Search for a compatible pre-built wheel on PyPI and install it directly.

Official docs:

• Microsoft: Manage required Python packages with requirements.txt

If you've solved the issue in your duplicate post or elsewhere, would you mind sharing what worked? That could help others with the same problem. Thank you!
