I got an error when trying to run the example code for dqn agent using this command: python examples/rl_dqn_agent.py --curriculum SimpleCartPole

Then I got this error: /home/user/anaconda3/envs/tella3/lib/python3.7/site-packages/gym/envs/registration.py:307: DeprecationWarning: The package name gym_minigrid has been deprecated in favor of minigrid.

Thanks for the report @furqon3009. I've fixed the dependency issue and deployed version 2.1.0 to PyPI.
