  note: This error originates from a subprocess, and is likely not a problem with pip.

hey @omkar-nath-reddy, we do not have pre-built wheels for Win/py313. Does your project require python 3.13 or can you downgrade to python 3.11. This way you won't have to rebuild the HNSW lib. Another alternative is to install chromadb-client which does not have chroma-hnswlib as dependency and run Chroma as a server in a docker container.

If none of the above works for you you will have to modify your Visual Studio installation to add Linux and embedded development with C++ and Python development packages in order to compile HNSW lib locally.
