求解答，YOLOV5 DeepSort 的试运行一直都有各种问题，这次实在不会了

Question

(deepsort) C:\Users\zhang\Desktop\Yolov5_DeepSort_Pytorch-3.0>python track.py --source test.mp4 --show-vid

Answer 1

UserWarning: torch.meshgrid: in an upcoming release, it will be required to pass the indexing argument. (Triggered internally at C:\actions-runner_work\pytorch\pytorch\builder\windows\pytorch\aten\src\ATen\native\TensorShape.cpp:2228.)
return _VF.meshgrid(tensors, **kwargs) # type: ignore[attr-defined]
修改为return _VF.meshgrid(tensors, **kwargs, indexing = 'ij') # type: ignore[attr-defined]，警告解除
