this pr is basically reverting #10223 . could you check?

Update:

Looks like order of the outputs depends on whether you use tflite model provided from the model zoo or you use converting code (checkpoint -> savedmodel -> tflite).

issue with not detecting anything if model is converted from checkpoint is still here.

Update:

Tried to do inference on checkpoint file as is, and looks like the weights are not trained (although filename implies it's epoch 301).
