Hi,

I follow the tuto and I have :

I use Windows
Python 3.9.10 (I tried with version above also)
NumPy 1.25.1 (I wrote import numpy ; print(numpy.__version__)
I installed with pip, it was not working and conda, it was not working also
I tried de pip uninstall numpy; pip install numpy

And when I try to click on go-web.bat I have this error. Could you help me ?

Importing the numpy C-extensions failed. This error can happen for

installed.

You should uninstall your python environment in your system.
