How do you fix "runtimeError: package fails to pass a sanity check" for numpy and pandas?

This is the error I am getting and, as far as I can tell, there is nothing useful on the error link to fix this.

RuntimeError: The current Numpy installation ('...\\venv\\lib\\site-packages\\numpy\\__init__.py') fails to pass a sanity check due to a bug in the windows runtime.

See this issue for more information: https://developercommunity.visualstudio.com/content/problem/1207405/fmod-after-an-update-to-windows-2004-is-causing-a.html

I have tried multiple versions of Python (3.8.6 and 3.9.0) and numpy and pandas. I am currently using PyCharm to do all this.

Solution 1:

This error occurs when using python3.9 and numpy1.19.4 So uninstalling numpy1.19.4 and installing 1.19.3 will work.

Edit

As of January 5th 2021 numpy version 1.19.5 is out and appears to solve the problem.

Solution 2:

I am using Python 3.7, anyway the same solution suggested here helped me.

pip install numpy==1.19.3

Actually the link informed https://developercommunity.visualstudio.com/content/problem/1207405/fmod-after-an-update-to-windows-2004-is-causing-a.html shows the given solution. It seems to be a bug in Visual Studio, which remains unsolved up to this date.

Solution 3:

Just install numpy==1.19.3 I am using python 3.9

Solution 4:

As per the discussion on the link you provided, a numpy dev answered:

NumPy has released a bugfix 1.19.3 to work around this issue. The bugfix broke something else on Linux, so we had to revert the fix in release 1.19.4, but you can still install the 1.19.3 via pip install numpy==1.19.3.

So, if you need requirements that work for both Linux and Windows, you'll need to use PEP508:

numpy==1.19.3; platform_system == "Windows"
numpy>=1.19.4; platform_system == "linux"
