StraightDog31 how did you get these ?
It seems like it is coming from maptplotlib, no?

We are using matplotlib in some tasks

are you using matplotlib ? could it be the binding check if matplotlib exists ? could it be you are running it with DEBUG on (i.e. global log level debug) ?

I would guess that for some reason loglevel is DEBUG, could that be the case?

Yes it is. They come always for us. Even if there is no matplotlib in requirements
