Output when running python run.py:

mlagents_envs.exception.UnityTimeOutException: The Unity environment took too long to respond. Make sure that :
         The environment does not need user interaction to launch
         The Academy and the External Brain(s) are attached to objects in the Scene
         The environment and the Python interface have compatible versions.

The Unity application actually open, but the level doesn't appear, it looks like below:

I have a feeling that the Unity app was trying to connect with some port to reach the python app but for some reason cannot and crashed itself internally?

You should look at this issue : https://github.com/Unity-Technologies/obstacle-tower-env/issues/46 You will need to use the v1.0 of ObstacleTower data instead of the 1.1 for now.

Hi @louisgv

We have also addressed this in a new version (v1.1.1) here: https://storage.googleapis.com/obstacle-tower-build/v1.1/obstacletower_v1.1.1_windows.zip which fixes this as well, and includes other fixes over v1.0
