Hello,

I have subscribed to the Python list.
The user name (which was optional) I entered as hsb3852, not my real name.
Does this matter?

My question is below…

Hello,
?
I’m quite new to Python (but not new to programming), and I’ve encountered problems with pip which I have been unable to solve.
?
When I tried to update pip using “python.exe -m pip install --upgrade pip” (I tried to install another package -unsuccessfully, which informed me there was a new version of pip), which failed with the following error:
?

WARNING: You are using pip version 20.2.2; however, version 20.2.3 is available.

C:\Program Files\Python38>

I checked that the file t64.exe does exist in the location (path) listed (C:\Users\user\AppData\Roaming\Python\Python38\site-packages\pip\_vendor\distlib\scripts).
This path is included in the PATH environment variable.
?
Why is this upgrade failing? How do I fix it?
?
I get this same error when I try to install other packages too.
?
The package I tried to install was numPy.
?
I also need to install cv2 and OpenCV, but my searches for them in PyPA returned dozens, if not hundreds of results. Can you perhaps indicate which versions I need to install on my Windows 10 PC?
?
Please help as soon as possible by return email.
?
Many thanks!
