kitti training

[hhhhh74]

hi, thanks for your code sincerely, i got problems when i trained gaussian yolov3 with KITTI dataset,
1.first is the environment setting, the recommended matplotlib vision is 3.0.2, but after i update it into 3.3 it stills exists similar warnings

2.next is the warning for invalid value, that:

3.with the above warnings the network can be trained, but the first evaluation AP is all 0, which is the most confused one

Could you please give some advice on where the reason is, it would be very helpful
