Running dopamine on obstacle tower

Unity Obstacle Tower Challenge
#1

Hi
Am getting this:
“The Unity environment took too long to respond. Make sure that :\n”
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.
In call to configurable ‘create_otc_environment’ (<function create_otc_environment at 0x7f8abb4b42f0>)
In call to configurable ‘Runner’ (<function Runner.init at 0x7f8abb4c1598>)
In call to configurable ‘create_runner’ (<function create_runner at 0x7f8abb4c1400>)

Could it be related to an earlier error:
Preloaded ‘libgrpc_csharp_ext.x64.so’
Unable to preload the following plugins:
ScreenSelector.so

Thanks

Hi @karl

Can you share a little more about the environment you are running it on?

Hi @arthurj
Am using ubuntu 18.04.2 x64 (from virtualbox on win10)

It sounds like you have a screen then for your Ubuntu installation. Would it be possible to try launching the binary by double clicking it from Ubuntu? If that works, I would next recommend trying it from our basic usage notebook: https://github.com/Unity-Technologies/obstacle-tower-env/blob/master/examples/basic_usage.ipynb. Please let me know if (and what) errors you encounter under these circumstances.
