Working directory problem in Mario GAN

[ttusar]

When calling the example experiment in C on the rw-mario-gan suite, i get the following error:

I think it is a working directory problem as I'm calling this from 'D:\Delo\Github\ttusar-coco\' and not 'D:\Delo\Github\ttusar-coco\rw-problems\mario_gan', so it does not find the file generator_ws.py

With @TheHedgeify we found that the problem was caused by a mix of separators (the path had both '\' and '/').

On Linux, the error message is as follows:
