Hi. gym don't make supermario

gym.error.UnregisteredEnv: No registered env with id: ppaquette/SuperMarioBros-7-2-v0

all version same.

I seems I have found the solution, you can follow the gym-wiki to register env manually.
git clone https://github.com/ppaquette/gym-super-mario
On my computer
cp -r ~/gym-super-mario/ppaquette_gym_super_mario ~/gym/gym/envs
Register env in /gym/envs/init.py:

register(
     id='SuperMarioBros-1-1-v0',
     entry_point='gym.envs.ppaquette_gym_super_mario:MetaSuperMarioBrosEnv',
)

Add your environment to the scoreboard in /gym/scoreboard/init.py

add_group(
     id='ppaquette_gym_super_mario',
     name='ppaquette_gym_super_mario',
     description='super_mario'
 )

 # mario bros
 add_task(
     id='ppaquette/SuperMarioBros-1-1-v0',
     group='ppaquette_gym_super_mario',
     summary="SuperMarioBros-1-1-v0"
  )

It works for me , you can test it by create a python file: test.py

import gym 
env = gym.make('SuperMarioBros-1-1-v0')
observation = env.reset()
for _ in range(1000):
    env.render()
    action = env.action_space.sample() # your agent here (this takes random actions)
    observation, reward, done, info = env.step(action)

Please note that gym changed 21 days ago, resulting in major change within gym/scoreboard. For me the only solution was to revert gym to the state where scoreboard was still at old version. See #16

Please also note that based on @Jackiexiao suludion only gym.make('SuperMarioBros-1-1-v0') will work.

@Jackiexiao's method solve my problem. But it's not very specific and has a few mistakes.
More specifically, first clone the repository git clone https://github.com/ppaquette/gym-super-mario
Then copy ppaquette_gym_super_mario to your gym/envs directory, for me it's /usr/local/lib/python3.5/dist-packages/gym/envs/
So the command is cp -r gym-super-mario/ppaquette_gym_super_mario /usr/local/lib/python3.5/dist-packages/gym/envs/
Add this to your gym/envs/__init__.py to register env

register(
     id='SuperMarioBros-1-1-v0',
     entry_point='gym.envs.ppaquette_gym_super_mario:MetaSuperMarioBrosEnv',
)

Add your environment to the scoreboard in your /gym/scoreboard/__init__.py

add_group(
     id='ppaquette_gym_super_mario',
     name='ppaquette_gym_super_mario',
     description='super_mario'
)

# mario bros
add_task(
     id='ppaquette/SuperMarioBros-1-1-v0',
     group='ppaquette_gym_super_mario',
     summary="SuperMarioBros-1-1-v0"
)

Now we done, you can test by this code

import gym 
env = gym.make('SuperMarioBros-1-1-v0')
observation = env.reset()
for _ in range(1000):
    env.render()
    action = env.action_space.sample() # your agent here (this takes random actions)
    observation, reward, done, info = env.step(action)

And the gym_pull code doesn't work now.

Cool. Nuance: you can get that path for the cp command etc by doing python -c 'import gym; print(gym.__path__[0])', so a generic cp command could be eg:

cp -r gym-super-mario/ppaquette_gym_super_mario \
    $(python -c 'import gym; print(gym.__path__[0])')/envs/

or we can copy to a var first, to use in other commands:

GYM=$(python -c 'import gym; print(gym.__path__[0])')
cp -r gym-super-mario/ppaquette_gym_super_mario ${GYM}/envs/

thanks all of you very much!!! its working now,the first thing to do to resolve this problem is to degrade you gym to 0.9.3 ,and you could import gym.scoreboard then, and then do as what liuny05 said.

I tried using an extended version of @Jackiexiao's solution that registers all of the individual stages, found here:

Env: https://gist.github.com/messiest/69569e8151d67c346eb609a0666d43b3
Scoreboard: https://gist.github.com/messiest/36a5cbb35dc57db2e480b4cf300e7223

However, regardless of which stage I try to make (i.e. gym.make('SuperMarioBros-8-2-v0')), it always loads the first stage, 1-1.

Does anyone have any idea what could be causing this?

Thanks!
