can't install umap-learn in python 3.10.2

[vmgustavo]

When I add umap-learn using Poetry it finds the requirements versions as:

• Installing llvmlite (0.34.0)
• Installing numba (0.51.2)

But fails to install numba as the first version of Numba that supports Python 3.10 is 0.55.0 (Numba 0.55.0 Release Notes)

This is the error message I get:

  ERROR: Command errored out with exit status 1: .venv/bin/python -u -c 'import io, os, sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-req-build-ooas2vcd/setup.py'"'"'; __file__='"'"'/tmp/pip-req-build-ooas2vcd/setup.py'"'"';f = getattr(tokenize, '"'"'open'"'"', open)(__file__) if os.path.exists(__file__) else io.StringIO('"'"'from setuptools import setup; setup()'"'"');code = f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /tmp/pip-record-6xue7xjo/install-record.txt --single-version-externally-managed --compile --install-headers .venv/include/site/python3.10/numba Check the logs for full command output.

It should work with numba 0.55; 0.51.2 is a minimum numba version. Perhaps this is to do with poetry?

It is indeed a problem with dependencies versions that poetry is trying to fix but failing. I am getting this log when it tries to install numba:

I added the following dependency in my pyproject.toml, and this helped poetry lock properly:

llvmlite = ">=0.39.0dev0,<0.40"

My guess is that numba should add that requirement explicitly when using python 3.10 (not sure if the requirement exists or not, though). Any longer term solucion?

[masylum]

I solved it by installing the last version of numba (0.57) (poetry add numba) since it has support for python 3.10+
