Thank you so much! This has really solved all you have listed.

@melmi525 That's awesome. Thank you.

What a genius! This is really all-in-one

Most of the packages listed are already specified in the requirements.txt file so its good to add
pip3 install -r requirements.txt

So that correct package versions will be installed
