Error when training ML-agents Penguin Tutorial: Environment stopping

Hi
I am very new to this and just started to follow the ml-agents: penguins.
After I started training (by entering the command in Anaconda Prompt) and pressed the playing button in the Unity Editor, it gives me below error:

====================================

Further investigation determined it is due to UnityTimeOutException error. Could anyone help, much appreciated!!

Ml-agent version 0.13.1
Unity 2019.3.8f1
Barracuda ver 0.4.0

 

If you follow the latest penguin example from this link, you should have the exact version of the environment that the demonstrator has, i.e. ML-agents 0.14.0 and Unity 2018.4.14f1.
