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)
 Requirement already satisfied: pip in c:\programdata\anaconda3\lib\site-packages (22.0.4)

 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)

and lastly, when I execute import matplotlib.pyplot as plt resuts in:

AttributeError: module 'matplotlib' has no attribute 'get_data_path' 

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

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