I encountered some inexplicable problems when I installed the Sklearn package, and finally found that the whl file was missing. After many searches, I found some more reliable tutorial posts:
whl file download website: https://www.lfd.uci.edu/~gohlke /pythonlibs/
No need to go over the wall
, Zhihu has a very comprehensive installation tutorial: https://zhuanlan.zhihu.com/p/624374119?utm_id=0
describes it very clearly
If you encounter other errors in the middle, copy them out and look for them until sklearn can be used normally
I have so many inexplicable and colorful error reports that ordinary people should not encounter, so I will post them as a reference
