How to setup behavior cloning

Hello,
I have been reading the doc about behavioral cloning and tried so set it up on a small toy example.
However, after adding the behavior_cloning section in my .YAML config file, Unity returns the error :

Code (CSharp):

1. mlagents.trainers.exception.TrainerConfigError: The option behavior_cloning was specified in your YAML file for TrainerSettings, but is invalid.

As you can see in the config file that I converted to .txt to upload it in the post, I simply added a behavior_cloning section in the config file with the different parameters according to what I want.
What I am doing wrong please ?
Thank you for your attention.

 

It's just a typo - write behavioral_cloning, not behavior_cloning

 

Indeed! Thank you.

 

bro you just saved me! ive been trying to figure this out for an hour
