1. Where to get the detection file? The detection files are generated by your own detector following the nuScenes format. Some public released detectors also release their files, such as CenterPoint.
2. How to evaluate nuScenes? After converting the tracking result to nuScenes format, you will get a .json file following the nuScenes tracking specifications. Then you may need to refer to the nuScenes official repo nuscenes-devkit for evaluating the tracking results with the .json you just produced.

@liangchunlan Hope the above information is helpful.
