How to train ResNet on person and vehicle ReID datasets like MSMT17 and VeRi?

[MuhammadAsadJaved]

Hi, I want to train ResNet-50 or 34 for person and vehicle on MSMT17 and VeRi dataset.

1- Can I train ResNet for two classes and use both datasets at the same time or I can train only and it's not suitable for two classes?
2- What is the training process?
2- Can I also use ResNet-18 or ResNet-34 in the same way to increase the speed?

My ultimate goal is to train ResNet ReID model for the person and car. and then combine with this project (https://github.com/GeekAlexis/FastMOT) for Fast multi-object tracking.

How I can achieve this goal?
