Hi,
There is an error when using the gym_walk module:
user:~/catkin_ws/src/rl_course_files/fly_drone/scripts$ python mc_fvmc.py
[2022-10-26 13:18:20,470] Making new env: RandomWalk-v0

from gym.envs.toy_text.utils import categorical_sample
ImportError: No module named utils
I tried to search about this module into the gym_walk distribution but it apparently does not appear. I can not continue with the course because of this.
Could you help me please?
Regards,
