I guess as #360 mentions swig 4 breaks Agg backend specifically. Maybe this should just be a warning here instead of raising? Saying beware agg won't work but if you wanna use non agg, go right ahead as you are?

I think this should be an error. Warnings during installation might be ignored.

i'm not sure why you removed swig from the dependencies list here. Without this, swig won't get installed via edm into the python environment.

it was listed twice, see line 104, I should have mentioned that

ahh. i should have noticed that things were not in alphabetical order - which i what i was kinda expecting.
can you rearrange the set alphabetically, for readability? this could be done in a later PR

i'm not entirely sure what raises the FileNotFoundError

if swig is not installed, then swig -version causes this:

Do we not run flake8 as part of CI in this project? |
We don't from the looks of it. |

This is a follow up to #808 which closes #769
This PR checks the version of swig via a subprocess call (a little ugly but seems to get the job done) in setutp.py.
If swig is not around or we have a bad version (not version 3.x) we raise an exception. This follows the second point at the end of the 769 issue description
