Troubleshooting

You may run into some unexpected errors when running chemgymrl environments from time to time.

Here we will discuss some possible error messages here and try to find a solution to them.

Errors

Not adding an entrypoint when registering an environment

register(
    id='WurtzExtract-v1',
    entry_point='chemistrylab.extract_bench.extract_bench_v1:WurtzExtract_v1',
)

AttributeError: module 'chemistrylab.extract_bench.extract_bench_v1:WurtzExtract_v1' has no attribute 'WurtzExtract_v1'

When registering any environment it's important to note that the corresponding entry point must also be added. In the picture above the entry point to WurtzReact-v1 was expected to be the class WurtzExtract_v1 in reaction_bench_v1.py. Failure to add the corresponding class will result in this error message.

Not registering an environment

>>> env = gym.make("WurtzReact-v1")

gym.error.UnregisteredEnv: No registered env with id: WurtzReact-v1

When adding a new environment it's required to also add a registration entry in chemistrylab/__init__.py. Failure to properly register a new environment will result in this error message.
