Running an ImageAI training returns always 0 loss
For me, what solved the issue was using batch size > 1.
I am trying the typical hololens tutorial to use Tensorflow, Keras, and ImageAI to be able to train a new custom object detection.
The training is running, but it is always returning something like: 
loss: 0.0000e+00 - yolo_layer_1_loss: 0.0000e+00 - yolo_layer_2_loss: 0.0000e+00 
And when I try to use the outcome of the model, it fails.
I am using Python 3.7.7
tensorflow           1.14.0
imageai              2.1.5
Keras                2.3.1
