Hi all! Quite new to Unity, I'm more from a machine learning background. Planning to use ML Agents, and write some custom python / tensorflow scripts for it. Is it possible to train based on external data added to unity environment data? So for example having additional image data to feed as input to the network beside the Unity camera? More of a global question is: how much is ML Agents limited to the Unity environment? Haven't really seen that so far in the examples and documentation. Thank you!
