Erro reproduction:

• Download this video from UCF-Crime dataset:
• Exec: python3 scripts/demo.py video.source=Normal_Videos465_x264.mp4 video.output_dir=./output

It will raise an error:

Possible solution:

• In PHALP/phalp/models/predictor/pose_transform_v2
• replace t_end.append(t.item()) to t_end.append(t.item() if torch.is_tensor(t) else t)
