mAP 0 on custom dataset for Car tracking

[DariusCorp]

Hello, I am using a custom 1000 images dataset like FLIR ADAS for car tracking. I have successfully converted all the data to fit the example datasets, and the model can train on it. The problem is that mAP is always 0 even after 300 epochs.
I am running on Nvidia Quadro RTX 5000, batch size is 8, my image size is 640x480, the cfg chosen are 864x480. What could be the problem here? I tried running on different cfg but still no improvement

These are training losses for epoch 12:
