Thank you for your work! I tried using it for training for more classes ( 6 classes ) on Lyft Dataset. I updated input/bdd_input.py
file to suit the needs of Lyft dataset. It also required changing hypes/kittiBox.json
to reflect new image dimensions. (height: 1024, width: 1248)
While trying to train, I ran into a few weird issues.

Have you by any chance encountered something similar while dealing with the training.
Any insights into this from your expertise would be very useful.
