I was able to successfully install and work with the OSMNX library. When I was almost at the end I installed ffmpeg and this completely fucked up the dependencies. Now I am not able to make the script work again. The problem seems to depend on the gdal package, that make fiona not work correctly, which in turn makes geopandas not work correctly. And without geopandas, OSMNX doesn't work.
I need help to make those libraries work together again.
