Environment isn't getting created upon running test_policy_gradients.py

[sankethvedula]

Hi,

I am kind of new to this OpenAI Gym.

While I was trying to run the test_policy_gradient.py file, I am getting the following error.

[2017-04-16 07:51:37,265] policy_gradient logger started.
[2017-04-16 07:51:37,266] Making new env: trading-v0
Traceback (most recent call last):
  File "test_policy_gradient.py", line 17, in <module>
    env = gym.make('trading-v0')
  File "/home/ubuntu/gym/gym/envs/registration.py", line 161, in make
    return registry.make(id)
  File "/home/ubuntu/gym/gym/envs/registration.py", line 118, in make
    spec = self.spec(id)
  File "/home/ubuntu/gym/gym/envs/registration.py", line 147, in spec
    raise error.UnregisteredEnv('No registered env with id: {}'.format(id))
gym.error.UnregisteredEnv: No registered env with id: trading-v0

trying to debug, I included " import gym_trading" in the beginning of the file.

Now, I am facing the following error

I understand that for some reason, the data frame isn't getting downloaded when I "make" the gym to create an environment, which is why I suspect I am getting this error.

Could you please point out where I am going wrong? Or if there is any fix around this?

Thanks a lot in advance!
Sanketh

this worked for me, it is in the init.py file in he gym_trading folder

from gym.envs.registration import register

register(
id='trading-v1',
entry_point='gym_trading.envs:TradingEnv',
timestep_limit=1000)

I'm having the same issue - and both proposed solutions didnt work...

[ackdav]

here is the error:

[2017-06-07 14:21:50,524] policy_gradient logger started.
[2017-06-07 14:21:50,524] Making new env: trading-v0

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

tried importing gym_pull as suggested, but "no module named gym_trading"

[baolinliu]

id='trading-v1', called the environment v1

[ackdav]

@baolinliu thanks but how does that help? Now it's:
gym.error.UnregisteredEnv: No registered env with id: trading-v1

[ackdav]

I tried around for a few days, but in the end it worked with sudo pip install -e . I'm not sure why using the -e flag made it work.

also I had to move the register call into test_policy_gradient.

Additionally with newer gym version you'd need to call env=env.unwrapped

[lwhuang]

can't get it work.
what's the install procedure?
pip install -e .
shows
Running setup.py develop for gym-trading
Successfully installed gym-trading

but still gym.error.UnregisteredEnv: No registered env with id: trading-v0

[crescentluna]

according to registration.py of gym library, env object is wrapped in a TimeLimit object
env = TimeLimit(env, max_episode_steps=env.spec.max_episode_steps,max_episode_seconds=env.spec.max_episode_seconds)
so use env.env to run those methods such as run_strats

[sophieyl]

the reason is that the environment did't register into the gym module.
change the init.py file in the same directory with env as below:
from gym.envs.registration import register

register(
id='trading-v0',
entry_point='gym_trading.envs.trading_env:TradingEnv',
timestep_limit=1000,
)
the entry_point should be 'gym_trading.envs.trading_env:TradingEnv'

[erdult]

still not working

[melseifi]

Not working for me either. If I include import gym_trading, it doesn't pass this step. and if I comment it, I get the registration error above.

After some packages update(e.g. the gym module), the notebook in the github will throw errors. So I fixed some of the issues and also made the corresponding changes required so that it can run smoothly in colab.
You may find the colab notebook link here: https://colab.research.google.com/drive/14OIx32e_pzqpMIhhRcPV5CMAHUAwVQK1

After running this code:

trading_environment = gym.make('trading-v0',
ticker='AAPL',
trading_days=trading_days,
trading_cost_bps=trading_cost_bps,
time_cost_bps=time_cost_bps)
trading_environment.seed(42)

I get an assertion error and I don't know how to get past it if anyone can help.
