Cannot uninstall numpy,

Question

I'm trying to use pip to uninstall numpy(I also installed pandas, but I seem to have been able to uninstall that). In the case of `numpy, I get the following output.

pip3 uninstall numpy -vvv --log pip.txt

Uninstalling numpy-1.12.1:

  /usr/lib64/python3.6/site-packages/numpy-1.12.1-py3.6.egg-info

During handling of the above exception, another exception occurred:

I've got a Fedora 26 system running both Python 2.7.15 and Python 3.6.5

I'm very new to Python (just started learning it last night), so forgive the ignorance. I've seen several related questions (mostly dealing with pip installs rather than uninstalls. None of them seemed to solve the issue. I should also note that I've read in these other posts that running pip as sudo is a bad idea (something I did while trying to install pandas because I didn't have permissions (and again, I read later on that that is a bad idea). Any help here is appreciated.

Answer 1

For python3:

sudo pip3 uninstall numpy

For python:

sudo pip uninstall numpy

or using:

sudo apt-get remove python-numpy

Answer 2

I had a similar problem with numpy and I just had to remove the package using apt (In your case is yum). Try to do:

sudo yum remove python3-numpy

Answer 3

Try running it with root authorization

    sudo pip3 uninstall numpy

It should work, most of the times.

Answer 4

in your case

sudo apt remove python-numpy

and

sudo pip install numpy==[Version you need]
