Why is it that im getting this error, when i have added gym.register for the environment in the init.py

this is the error:

Same error here: For some reason, it always refers to the init.py file in the ~/miniconda3/envs/isaaclab/lib/python3.10/site-packages/gymnasium/envs folder. The locally generated init.py file like it is described in the IsaacLab docs, which is generated on the same level as the environment.py-file (here: bin_pick_sm.py). Can anybody say how to connect the environment file with the init.py file???

Thanks for posting this. Is the error found with Isaac Lab 1.3? Thanks

Yes, the error is found in IsaacLab 1.3. I did also solve it now: I put my main and my train function as well as the environment configuration in the same python-file. Separating the environment file in a env.py and the training into a train.py and importing the environment into the train.py I did not have a problem anymore. I can't explain, why it is like that but now it works...
