Hi @natabene!! I created this PR to solve the python 3.8 dependencies conflicts since I had been experiencing similar issues in another repositories so I would like to ask for the last review here and once it's merged we could closed the original. Thank you so much for your support!!

Looks like this one is missing the dependency change from #176. Would it make more sense to go back to the original PR, remove the .txt requirements changes, rebase, and then re-compile requirements?

[NeOneSoft]

Hi @timmc-edx, thank you so much for your support!!. What you suggest makes sense for me!! I only continue using this PR to test if the changes on the dependencies works since it was a little bit confusing for me. In fact I believe that now this is ready !!
