I am on Raspberry Pi 4.
Trying to run a script needing Pandas and Numpy.
I am getting this error for which I have not found any reference to read and attempt to solve the issue:

Numpy is installed. I did clean up previous installations of Numpy because was giving errors with Pandas. Not sure about what to do anymore to get Numpy and Pandas correctly installed.
The last Numpy installation I did was with `python3 -m pip install numpy`
I do I solve this issue?
