Importing the multiarray numpy extension module failed (Just with Anaconda)

Question

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?

Answer 1

I feel like I would have to know a little more but, it seems to be that you need to reinstall numpy and check if the complete install was successful. Keep in mind that Anaconda is a closed environment so you don't have as much control.

with regards to the permissions issue you may have installed it with a superuser/admin. That would mean that in order to update you would have to update with your superuser/admin.

Answer 2

以下为我解决了这个问题：

pip install --upgrade --force-reinstall numpy

Answer 3

Kindly perform invalidate cache and restart if you are using PyCharm.

No need to uninstall numpy or run any command.
