Dependencies?

[theUtmostgit]

Hi, sorry total noob here.
While I don't know anything about coding or Python, I have used and modified a couple of simple old-school bat files, and I think this script is exactly what I'm looking for, ie to show all torrents in Download Station that do NOT have tracker Status = "Success"
Alas, when I run it both on my NAS and also on Windows from idle, I get the same error msg:

Traceback (most recent call last): File "app.py", line 1, in <module> import requests ModuleNotFoundError: No module named 'requests'

It seems from reading the "requirements.txt" there are dependencies I am lacking in either the NAS or on Windows 10?
One of which is something called requests, so it seems likely I'm missing ALL items listed in that txt file
NAS is running DSM 7.0.1-42218 Update 3

Does this need compiling? and including those other dependencies?
I dunno how to do that...
Any guidance on how to use would be gratefully received.
Yes I have edited the app.py file to change the BASE_URL and USERNAME values inside
Cheers,
