While i run the parking_model_based.ipynb example, the google cloab get a error: ImportError: cannot import name 'RecordVideo' from 'gym.wrappers' 。

Interesting, apparently gym==0.17.3 is installed by default on Colab, but the RecordVideo wrapper only appeared on gym==0.21 or 0.22. I recently made it a required dependency of highway-env, but I havent generated a stable version with this change yet, which is why the gym version does not get upgraded automatically when installing stable highway env.

In the meantime, you can fix it either by installing the dev version of highway env; i.e. replace !pip install highway-env by !pip install git+https://github.com/eleurent/highway-env

or alternatively simply add !pip install gym==0.23.1 in the beginning.
