Following the guide to gym-gazebo installation and some workarounds concerned with the cv2 import error which took me an entire week of debugging and help from external sources. Being new to this domain certainly does not help. Right now I am yet again at crossroads with the below mentioned problem and haven't been able to find any solutions so far. Any and all suggestions and help is appreciated.
