[Python] Trouble installing hdbscan package for python : "no module named 'hdbscan'" error

I want to run an algorithm written in Python on my Ubuntu virtual machine. It needs to import the hdbscan module. I thus want to install it on my virtual machine.

Following the documentationfrom Pypi.org about this library, I simply ran :

pip install hdbscan


After a few minutes, it returned :

Succesfully built hdbscan
Installing collected packages: hdbscan
Succesfully installed hdbscan-0.8.27


However, if I run my algorithm, it still says that there's "No module named 'hdbscan'".

I tried pip uninstall hdbscan but it then returns :

WARNING : Skipping hdbscan as it is not installed.


I have tried several commands to fix this issue, like for example sudo apt --reinstall install hdbscan or pip install --upgrade git+https://github.com/scikit-learn-contrib/hdbscan.git#egg=hdbscan

All I get as a result is "successfully installed" or "requirement already satisfied" but my algorithm still can't use it, "is not installed" or "unable to locate package hdbscan" alternatively as I try one command or another.

I don't know what is the cause of the problem nor how to fix it. Can anyone help me please ?
