MLAgents bug

[JoseRFJuniorLLMs]

I downloaded the project and tried to run, gave this error? do you know why ?
Assets\AngryAI\Scripts\ML\DemoAcademy.cs(1,7): error CS0246: The type or namespace name 'MLAgents' could not be found (are you missing a using directive or an assembly reference?)

Looks like the ml-agents files are missing in the Assets directory
