Tests fail with ModuleNotFoundError: No module named 'hdbscan._hdbscan_linkage'

[TheChymera]

I'm currently working on packaging your software for Gentoo Linux, and it seems to install fine (no errors, import hdbscan works), but the tests fail.

This is the full build and test log https://ppb.chymera.eu/072aa2.log
Any idea what I might be doing wrong?

Did you find a solution to this issue, as I'm having the same problem trying to write a new test function?

[TheChymera]

@JanRhoKa I have not :( the parts of the package which I need (used as a lib by tridesclous) seem to work, though...

[JanRhoKa]

I have found a solution:

Create env

conda create -yn hdbscan-dev -c conda-forge python=3.8 ipython ipykernel numpy pandas cython
conda activate hdbscan-dev

Tried to install setup.py with python setup.py develop but that resulted in some errors (fixed below)

#Error: Microsoft Visual C++ 14.0 is required
Fix for Microsoft Visual C++
Download and install package into the folder of the newly created hdbscan-dev env (anaconda3\envs\hdbscan-dev)

Again tried to run setup.py develop
#ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

Fix for the Value Error

conda uninstall numpy 
y
conda config --env --add channels conda-forge
conda install numpy

After that the setup.py can be developed.

Install
python setup.py develop

All of this was done on windows 10 using the PyCharm 2021.2.3 terminal.
