DEPRL cannont train new env

[LoFull]

Dear team，
Hello, I now want to train my newly created Environment with deprl. I have successfully run the rendered image through "Test Environment" when I use:python -m deprl.main baselines_DEPRL/myoLegWalk_zhao.jsonan error occurred.The error message was:

Traceback (most recent call last):
  File "/home/rb/anaconda3/envs/my/lib/python3.8/site-packages/gym/envs/registration.py", line 132, in spec
    return self.env_specs[id]
KeyError: 'myoLegWalkZhao-v0'

During handling of the above exception, another exception occurred:

gym.error.UnregisteredEnv: No registered env with id: myoLegWalkZhao-v0

Only my config file has been modified:
"environment": "deprl.environments.Gym('myoLegWalkZhao-v0', reset_type='random', scaled_actions=False)",

I'm sure the name of the gym environment has not been entered incorrectly. May I ask what the reason is?
