RuntimeError: boxes should be a 2d tensor, got 1D.

I tried to upload two pictures, but I got an error. RuntimeError: boxes should be a 2d tensor, got 1D.
Traceback (most recent call last):

return torch.ops.torchvision.nms(boxes, scores, iou_threshold)
RuntimeError: boxes should be a 2d tensor, got 1D

so, Is the way I execute the code wrong? could you tell me how to run it
