Error when retraining dashcamnet

BTW in the spec, I added several classes which are D00, D10… which stand for different types of holes on road.

In the spec, I did nothing regarding the original detectable objects types that are “cars”,“people”,“roadsigns” and “two-wheelers” cause I think I only intend to add the ability of detecting the “holes”, all my spec should be new detection class related. (which I don’t know if correct or not). If I am wrong, what should I do to include the old classes

thanks,
