module 'gym.envs.box2d' has no attribute 'CarRacing'

[zhouliang-yu]

Describe the bug
Hi!
When I try to run the code

env_id = "CarRacing-v1"  
env = gym.make(env_id)

there is a bug saying that "module 'gym.envs.box2d' has no attribute 'CarRacing'"

but before that, I did install the Box2D by pip install

System Info
The code is run on colab

• support version
  python3.7
  gym 0.17.3

• I have checked that there is a similar issue in the repo (gym')
  but still cannot solve my problem

Did you run pip install gym[box2d]?

I am also getting the same error. Also got an error when pip install gym[box2d] it says legacy-install-failure and I couldn't see any solution to that.

Did you run pip install gym[box2d]?

yes but still not work..

@zhouliang-yu You say you are using 0.17.3, however I can't find a release for that.

I have created a next python environment and run with no issue so this is strange
pip install gym[box2d]

import gym

gym.make('CarRacing-v1')

@zhouliang-yu and @edilgin Could you run, this should test if the issue is with gym.make or something else

import Box2d
import pygame
from gym.envs.box2d.car_racing import CarRacing
env = CarRacing()
env.reset()

yes
