Failed to run the code: JSSEnv not found

[smita-09]

First of all I would like to thank you for doing the implementation of the idea you proposed in your paper and also for such a real nice paper. Learnt a lot from it!
I am doing research in similar area and your paper has been a great starting point.

I am using Ubuntu 21.10 and Python version 3.9
While running the code I found lot of errors while installing the packages listed in requirements.txt because of the dependencies and deprecated versions so
and that makes sense because now lot of newer version of these packages are there and the older ones do no support so I tried installing the packages listed in requirements.txt by removing all the versions in there and it did install successfully.

But then somehow the JSSEnv is not available although I did install it.

Here is the error that I am getting and somehow I am stuck here, Any help will be appreciated alot.

Hi @smita-09

Thank you for your kind words :)

It seems there is some issue with the registration of the environment.
Could you try to add those lines at the beginning of the main file:

gym.envs.register(
    id='JSSEnv:jss-v1',
    entry_point='JSSEnv:JSSEnv'
)

This should register the custom environment and point the id to the correct entry point.

Example of the full script:

import gym

gym.envs.register(
    id='JSSEnv:jss-v1',
    entry_point='JSSEnv:JSSEnv'
)

env = gym.make('JSSEnv:jss-v1')
print(env.reset())

I hope this will fix your issue :)

I tried, it didn't work, I have the same issues..
