Python warnings occuring although disabled

Question

I have a rather large python2.7 project where due to package updates a set of warnings started to show up. For the time being, I want to disable them, to be able to fix another problem, before I can look into the warnings (I do know about the risks of ignorign warnings!). I have one 4-line main function calling the whole rest of the project. I already added warnings.filterwarnings("ignore") to my main programm, I added np.warnings.filterwarnings('ignore') to every file where numpy gets imported and I tried to use the -W option (all of these in various combinations).

Yet: the warnings still occur. Why is this and what can I do about it?

This is my output
