Module Not Found Error: Gym Module Cannot be Located

To solve the issue, one should check the version of atari_py in PyCharm IDE as some versions are no longer functional or miss a file (ale_c.dll). It’s important to choose the correct version of everything when installing atari_py and gym with Python. The newest version of Gym 0.21.0 (0.20.0 and higher) uses ale-py which works differently compared to the previous version. It is suggested not to use env.render() and games are v5 (all versions below v5 are from atari_py).


Solution 1:

From my understanding, it appears that you are attempting to utilize the website https://pypi.org/p/gym.

In order to execute the code

python

in the terminal, it is necessary to ensure that the

$

prompt is visible beforehand.

pip install gym

Once you execute

python

, you should then have the capability to run

import gym

.


Solution 2:

run this:

pip install gym

Then run your “import gym” again.


Solution 3:


I notice that you’re in the process of setting up a gym.

pip install gym 

is unnecessary.

Please, try:

import sys
sys.path.append('path')

The directory referred to is where the gym module is located.
