## You might encouter this problem after installing and sourcing the env on your machine

_You do not need to modify baselines repo._

Here is a minimal example. Say you have myenv.py, with all the needed functions (step, reset, ...). The name of the class environment is MyEnv, and you want to add it to the classic_control folder. You have to follow these steps

* Place myenv.py file in gym/gym/envs/classic_control

* Add to __init__.py (located in the same folder)

* from gym.envs.classic_control.myenv import MyEnv

* Register the environment in gym/gym/envs/__init__.py by adding

gym.envs.register(
         id='MyEnv-v0',
         entry_point='gym.envs.classic_control:MyEnv',
         max_episode_steps=1000,
    )

_At registration, you can also add reward_threshold and kwargs (if your class takes some arguments).
You can also directly register the environment in the script you will run (TRPO, PPO, or whatever) instead of doing it _

_in gym/gym/envs/__init__.py._

**Testing**
```shell
import Gridworld
import gym 
env = gym.make('Grid-v0')
```
