Umap: Unable to install Umap-learn

[nolzie]

python3.9
windows 10
When I run the command:
pip3 install umap-learn
I get the following error:
_Failed to build llvmlite
Installing collected packages: llvmlite, numba, umap-learn
Running setup.py install for llvmlite ... error_

_FileNotFoundError: [WinError 2] The system cannot find the file specified
error: command 'c:\scratch\python39\python.exe' failed with exit code 1_

does anyone know how to overcome this?

Especially for windows I'd recommend using conda and installing umap-learn
from conda-forge. In my somewhat limited experience with windows I've
historically had more luck using conda than pip.
Try something like:
conda install -c conda-forge umap-learn.

Python 3.9 is not currently supported -- since we make heavy use of numba which doesn't currently have a release that supports python 3.9

Hi,
As a big fan of UMAP, I am wondering if there are any (good) news about the possibility to use UMAP with Python3.9?

Version 0.53 of numba will provide python 3.9 support. Currently they are on the third release candidate of that version, so I would hope they will have a full release in the next month or so. You can always install the release candidate version ahead of time.
