Hi,
This is a duplicate of https://github.com/Unity-Technologies/ml-agents/issues/3336

You should either:

• downgrade barracuda to 0.4.0
• upgrade ML-Agents to 0.14.1
• use the branch from https://github.com/Unity-Technologies/ml-agents/pull/3339

I'm going to close this; please re-open if you have more problems.
