Replace PyQt5~=5.15.4 with PyQt5~=5.14.1 in requirements.txt

[INF800]

Need to downgrade for avoiding PyQt5.sip not found error. Tested in windows anaconda python 3.7.11.

Interesting cause I newer import PyQt5 sip anywhere.

Did you try installing it manually? → pip install PyQt5-sip

[INF800]

PyQt5-sip is internally imported by PyQt5. Yes I tried installing manually but I think there are some low level changes in either the latest version of PyQt5 or PyQt5-sip. Easiest approach was to downgrade PyQt5.

I tried it on my windows

Ok, might add a note referring to this issue for windows users.

But for Linux users it seems to work flawlessly.

Thanks for raising the issue!

Hey @INF800,

I am still on this. Yet it takes some time as I currently don't have access to a Windows machine.

Was your machine a 64 or 32 bit architecture?

[INF800]

It was 64 bit high end machine

An approach similar to this worked for me https://stackoverflow.com/a/62299050

Did the change for windows compatibility. Though would like to have a proper solution for this at some point as this seems not necessary for *nix platforms.
