title: unity ML Agents and external data
body: <p>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.</p>
  
  <p>Is it possible to train based on data from my harddrive additionally to unity environment data? So for example having additional image data to feed as input to the network beside the Unity camera?</p>
  
  <p>Haven't really seen that so far in the examples and documentation.</p>
  
  <p>Thank you!</p>
