Hi，thanks for your work first!

But when I'm trying to run
'python experiments.py evaluate configs/IntersectionEnv/env.json
configs/IntersectionEnv/agents/DQNAgent/ego_attention_2h.json
--train --episodes=4000 --name-from-config'

Something wrong happend:

import_module highway_env
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

gym.error.UnregisteredEnv: Environment intersection-v0 not registered. The environment module should be specified by the "import_module" key of the environment configuration

I've aleardy installed all the packages required,and I tried to find a solution online, but it didn't work.
Hope to receive your replay!

Well,I've found your earlier replay about the similiar issue.https://github.com/eleurent/highway-env/issues/431

Still thanks a lot!

But there's something wrong about visualization(The screen of videos saved are black.)
And I couldn't find out the cause of the problem.

Hope to receive your replay!

That is strange, I am unable to reproduce this issue of the videos being black.
You can for example run this colab, which produces a correct video.

i have the same error, and how to register the IntersectionEnv?

l solve it, in experiment.py, add the following,

import highway_env
highway_env.register_highway_envs()

enjoy it
