problems in pip install and matplotlib library installation

Question

to install matplotlib library its recomended uses this base:

python -m pip install -U pip
python -m pip install -U matplotlib

when I execute the following code:

(base) C:\WINDOWS\system32>python -m pip install -U pip

results in this warning:

 WARNING: Ignoring invalid distribution -atplotlib (c:\programdata\anaconda3\lib\site-packages)
 WARNING: Ignoring invalid distribution -atplotlib (c:\programdata\anaconda3\lib\site-packages)

 WARNING: Ignoring invalid distribution -atplotlib (c:\programdata\anaconda3\lib\site-packages)
 WARNING: Ignoring invalid distribution -atplotlib (c:\programdata\anaconda3\lib\site-packages)

so with -U matplotlib do:

WARNING: Ignoring invalid distribution -atplotlib (c:\programdata\anaconda3\lib\site-packages)

I don't know what to do, hope you can help me.

Possible duplicate of https://stackoverflow.com/questions/63826975/attributeerror-module-matplotlib-has-no-attribute-get-data-path-on-visual-s ? It "smells" like your matplotlib has not installed properly or else your environments are confused somehow. — Pam

Only delete if the other answer answers your question! Otherwise add enough information to differentiate your question from that other one and there will hopefully be a fix proposed. — Pam

Go to the location in the warning and look for folders starting with "~", if you find any, delete them and rerun the code.

Deleting the folders starting with '~' helped. Thank you very much! I did the upgrade of version and after that started to show the warning. The folders with '~' had previous version number in name. So I believe there was some confusion, as described above in comment from @Pam.

(kill the python process that handle them first)

It seems like you may have installed it incorrectly. Try executing

pip show matplotlib

Does it show the version installed?

If you are using anaconda, it should be installed through

conda install matplotlib

Open terminal (i.e., cmd) and go to the problematic folder, in your case c:\programdata\anaconda3\lib\site-packages but on my computer c:\python310\lib\site-packages. Then remove all the directories starting with ~, in my case:

~ip
~ip-22.1.2.dist-info

using the command from here:

for /f %i in ('dir /a:d /s /b ~*') do rd /s /q %i

then try upgrading pip again to be sure things are OK now:

python -m pip install -U pip

interestingly enough, I had the same issue on my macOS device as well on the /usr/local/lib/python3.10/site-packages, and the problematic folders being

~BB
~BB-0.2-py3.10.egg-info

I could easily remove them by going to the said folder and running

rm -rf ~*

Whether you encounter this problem when trying to install matplotlib or sqlalchemy the fix is simple and the same.

Try locating the folder it returns, (c:\python310\lib\site-packages) and delete any folder starting with ~
