FileNotFoundError: Could not find module ‘... dll‘ (or one of its dependencies).

In today's workstation Up operation python The program times the following error ：

FileNotFoundError: Could not find module ‘D:\Anaconda3\lib\site-packages\scipy.libs\libbanded5x.EVQBRDRR4US53IHPKU7YBJU2OAGXVHOG.gfortran-win_amd64.dll’ (or one of its dependencies). Try using the full path with constructor syntax.

I looked down the catalogue and found something related dll Files do exist .

At present, the best way is to reduce scipy Version to 1.6.2, Command line execution

conda install scipy==1.6.2
