New Learning Environment

Hello!!!
I need your help!
I have created my own environment and just want one agent to walk from one point to another.
I have tried to implement the existing examples in Unity - ML-Agents, so to understand what exactly have to be implemented, with succeess following the instructions of the tutorial. But in my own environment, I do something wrong.
If someone could help me , I would be very gratefull!!!
Thank you in advance!!!
When I try to train it, it appers these hugeeeeeee error message:

Yes I am using mlagents 0.10.
Fortunately I have found the solution !!!
Using this version I had not define correct the Brain parameters in the inspector window.(Vector action -> Branch descriptions).
Thank you for your time!!!
