Issues with pip in Python 3.8.3

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…

Best regards,

Hylton

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:

 �

ERROR: Exception:

ValueError: Unable to find resource t64.exe in package pip._vendor.distlib

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

You should consider upgrading via the 'C:\Program Files\Python38\python.exe -m pip install --upgrade pip' command.

 �

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!

Hylton
