Pycharm error: original error was: DLL load failed while importing _multiarray _Umath: the specified module could not be found

Anaconda is installed under the window system and the virtual environment is configured
everything runs normally using the command line, but an error is reported when running on pychram:
original error was: DLL load failed while importing _multiarray _umath

Tried:
1. Uninstall numpy and reinstall numpy
2. Add the python path again many times in the python settings

Final solution:
add system variables


after installing anaconda, only the first two are added, but not enough!!! \Bin and \library\bin should also be added!!!

Since it runs normally on the command line, the version problem between packages can be ignored. The problem must be the configuration of pycharm or system variables
