I downloaded a precompiled numpy
binary from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy and tried upgrading my current numpy
install on Windows 7 with
pip install --upgrade "numpy-1.10.4 vanilla-cp27-none-win32.whl"
I get the following error:
C:\Users\Jeroen\AppData\Local\Enthought\Canopy\User\Scripts\pip-script.py run on 04/01/16 13:20:05

NumPy 1.22. 0 is a big release featuring the work of 153 contributors spread over 609 pull requests. The Python versions supported by this release are 3.8-3.10.
I had the same message and for me it was simply needing to close eclipse before updating or reinstalling numpy. Not sure why, but this may help people having a similar problem to first make sure everything is closed.
I had a similar error message when trying to update numpy to 1.11. What worked for me was deleting the numpy folder manually from Lib/site-packages/ and then installing the whl (through a CMD-Window with admin rights) using the normal pip install command.
