DLL load failed while importing when sklearn is called_Arpack error

There is no effect after reinstalling sklearn and numpy with CONDA
some people in the Post said that they could delete some DLL files under Win32 to prevent error reporting and did not try

Knowing that CONDA may have its own problems (such as some DLL file configurations), I reinstalled sklearn with PIP

pip uninstall scipy
pip install scipy

The problem is solved (of course, the image should be configured in advance)

PS: I still reported an error when I just used the Jupiter notebook. I found that I had to restart it.
