`pip install chromadb` fails with python 3.11.0

TL;DR

What was reported: Issue chroma-core/chroma#163 (closed, 19 comments): steps to recreate: 1. open shell with python 3.11.0 2. run pip install chromadb 3. see error "ERROR: Cannot install chromadb==0.1.0, chromadb==0.2.0, chromadb==0.3.0, chromadb==0.3.1 and chromadb==0.3.2 because these package versions have conflicting dependencies." workarounds: 1. downgrade python to 3.10 to match dockerfile version full terminal output: ``` (chroma) jefflab@JeffsM1Air app % pip install chromadb Collecting chromadb Downloading chromadb-0.3.4-py3-none-any.

Steps

1. What works:

[HammadB (maintainer)]: chromadb pulls in PyTorch through sentence-transformers, and at the time PyTorch had no Python 3.11 wheels, so pip install chromadb failed on 3.11 with conflicting dependencies. Fix: use Python 3.10 or earlier for chromadb. If you must stay on 3.11, install the pytorch nightly build and build sentencepiece from source, but expect rough edges.

When to use

Use this skill when you run into "pip install chromadb fails with python 3.11.0".

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

Versions

Versions mentioned in the source: python 3.11.0, chromadb 0.1.0, chromadb 0.2.0, chromadb 0.3.0, chromadb 0.3.1, chromadb 0.3.2, chromadb- 0.3.4-py3. If you are on something much newer or older, the details may have shifted.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
