I am getting this error even after making changes and making a gym environment name RocketLander-v0. I don't know what i am doing wrong?

It's looking for the unofficial rocket lander environment. This branch should have the necessary changes on top of the latest version of gym: https://github.com/EmbersArc/gym/tree/addRocketLander

I did change the gym env/box2d/env folder by adding rocket_lander.py and changing __init.py file. but It is still showing error as same "GymEnvironment' object has no attribute 'env'". What am I doing wrong?

[EmbersArc]

Did you change both init files?

[ksajan]

yeah, I did in my original gym folder which i cloned and installed using pip install e . command

[ksajan]

it's showing this error
