yolo_training app not starting

Hello, I am trying to train the yolo model with custom objects to recognize different things (like cones, etc.) But before I do that, I am just trying to run the basic yolo_training app with the sim and it is giving me some vague errors.

I start the sim before I launch the app, as well as the carter_rgb_detection.json is updated with the absolute path to it’s corresponding config and graph files.

I was able to fix this issue by downgrading keras from 2.2.5, to 2.2.4. Might be something useful to add to documentation because the model.py code utilizes the keras.backend.control_flow.while_loop function which only worked on 2.2.4

Hi Navon,
This should be fixed with the new 2019.3 ISAAC release. Let us know if you still face any issues.
