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

Question

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 installa

Answer 1

Rolling back to numpy 1.19.3 worked for me on python 3.8.6

Answer 2

Why hasn't anyone posted the difference between 1.19.3 and 1.19.4.

The problematic numpy init code is:

def _win_os_check():
    """
    Quick Sanity check for Windows OS: look for fmod bug issue 16744.
    """
    try:
        a = arange(13 * 13, dtype= float64).reshape(13, 13)
        a = a % 17  # calls fmod
        linalg.eig(a)
    except Exception:
        msg = ("The current Numpy installation ({!r}) 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")
        raise RuntimeError(msg.format(__file__)) from None

if sys.platform == "win32" and sys.maxsize > 2**32:
    _win_os_check()

del _win_os_check

This code section doesn't exist in 1.19.3; that's the only difference.

Answer 3

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

Answer 4

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.

Answer 5

It's a bug of numpy 1.19.4 that fails with all python versions. Use the previous version to solve the problem, so by terminal:

pip install numpy==1.19.3

Answer 6

Just install numpy==1.19.3 I am using python 3.9
