Thanks @hossam-houssien for the report.

I don't have access to a Windows machine to test this.

However, based on the error it looks like it might be related to a problem with installing scipy on Windows, see for example:

https://stackoverflow.com/questions/34253458/installing-scipy-package-in-windows

There are a few suggested solutions mentioned in stackoverflow that might help. Would you mind checking if any of those help you fix the problem?

Searching for the error also pointed to a number of GitHub issues for Python software on Windows that depends on scipy. Seems like it might be a common problem.

issue fixed by

• uninstall scipy and numpy
• re-install scipy==1.6.1 and numpy==1.20.3
