Hello,
I have installed Python 3.9 on windows 10(I also installed Anaconda). after that I installed pip because I wanna install numpy. but when I import numpy, I see error below. Does anyone know what should I do to solve this problem?
Thanks

>>> import numpy as np

Error:

There seem to be several workarounds on that page, while a proper fix is in the works. Did you at least try any of them?

there are at least 2 workaround solutions + explanation when to expect windows fix of the issue that caused the underling bug in the first place (probably around Jan 2021).
The most straightforward workaround is to install exactly numpy 1.19.3 version

You say "there's nothing" in that thread, but there are several workarounds mentioned. Have you tried them and they don't work, or have you not tried them?

* Downgrade to numpy 1.19.3

Quote:pip uninstall numpy

then

pip install numpy==1.19.3

* Use WSL (windows linux) and python/numpy there.
* Install the 32-bit version of python/numpy.
