@wafa-sehar said in How do you fix “runtimeError: package fails to pass a sanity check” for numpy and pandas?:

can anyone guide me please.

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.

We have also 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.

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