Hi,

It seems that you have some problem installing numpy? Maybe try pip install numpy. If this does not solve the problem, you can also just clone the project and install it by python setup.py install.

Hi,

I encountered the same error while trying to install the package in a Python 3.10 environment with both methods (pip install and python setup.py). The issue at this line which specifies numpy<1.20 which is very old.
So the solution for me was to remove this constraint (replace the above line with numpy>=1.19.5) and then install using python setup.py install. And that worked for me.
Hope this helps.
