So, I have quite a problem here. PC with Win7, downloaded Winpython 3.7.12 that has Pandas 1.2.5, but my code needs Pandas min v1.3.
I do not know what the issue is but Spyder and "WinPython Control Panel.exe" do not work. Nothing happens when I run them.
But that is not the biggest problem, as I could probably find a way round those problems.
The thing is that I need Pandas min v1.3 and I am unable to upgrade this package. Older versions of Winpython also have a problem updating Pandas to v1.3.
Which version of Winpython should I download to be able to have (or to be able to upgrade to) Pandas v1.3 AND have Spyder and control panel working out of the box on Win?
Is there a way to fix the upgrading pandas problem?

More problems. I am unable to register python with the script provided in Scripts folder, I am also unable install pywin32 or pypiwin32.

`setup.py clean` is not supported, use one of the following instead:

  - `git clean -xdf` (cleans all files)
  - `git clean -Xdf` (cleans all versioned files, doesn't touch
                      files that aren't checked into the git repo)

Add `--force` to your command to use it anyway if you must (unsupported).

  - `pip install numpy`   (last NumPy release on PyPi)
