Importing the multiarray numpy extension module failed (Just with Anaconda)
Kindly perform invalidate cache and restart if you are using PyCharm.
No need to uninstall numpy or run any command.
I'm quite new to Python/Anaconda, and I'm facing an issue that I couldn't solve on my own or googling.
When I'm running Python on cmd I can import and use numpy. Working fine.
When I'm running scripts on Spyder, or just trying to import numpy on Anaconda Prompt this error message appears:

ImportError: Importing the multiarray numpy extension module failed.
  Most likely you are trying to import a failed build of numpy. If
  you're working with a numpy git repo, try git clean -xdf (removes all
  files not under version control). Otherwise reinstall numpy.
Original error was: cannot import name 'multiarray'

I don't know if there are relations to it, but I cannot update conda, as well. When I try to update I receive Permission Errors.
Any ideas?
