Hi
https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy also has a numpy wheel
1.19.4+vanilla‑cp39‑cp39‑win_amd64.whl
"Vanilla is a minimal distribution, which does not include any optimized
BLAS libray or C runtime DLLs."
Have not tried this.
cheers

HI
Just had the same problem.
The solution that worked for me was (
pip uninstall numpy
then
pip install numpy==1.19.3
The latest update to windows has an error in the BLAS libray causing the
error. its a known problem.
hope this helps

We store our preferences in an INI style config file which we've found easier
