Dear Anton,
Please confirm if I need to install LAPACK separately or not? Because installing it separately seems to be a tedious process involving CMake, visual studio. So I would rather move to Linux then. :(
Also, If I have to repair this installation, do I have to start all over with "pip install -U pip" commands?

Regards,

Regards,
