Issue

When I do pip install sklearn --upgrade, I got the following error:

Exception:
Traceback (most recent call last):
  File "d:\anaconda3\lib\site-packages\pip\basecommand.py", line 209, in main
    status = self.run(options, args)

PermissionError: [Errno 13] Permission denied: 'd:\\anaconda3\\Lib\\site-packages\\sklearn\\utils\\m
urmurhash.cp35-win_amd64.pyd'

The command prompt is run as an Administrator, so I have the permission.

What should I do? Any suggestion would be appreciated.

Solution

Have you installed its dependencies like numpy and scipy? Check it out and then we will proceed further.

Final Solution: try conda like conda install scikit-learn=_version_

I already have them. But when I try to upgrade them, the same issue occurs.

Hmm Why don't you try conda there? like conda install scikit-learn=_version_ @dixhom

Okay, I am updating my answer with this solution. Don't forget to up vote I want more reputations u know? ;) @dixhom

In my particular case, it was a different package. I changed the permission of the file but was not helpful. In the end, I just deleted the file (basically moved it to another location as a backup). On running the command again, it ran and the package also got restored by pip.
