Error on torch.load() (PytorchStreamReader failed)

Hi! New member here! I am following this code: How to Train YOLO v5 on a Custom Dataset | Paperspace Blog
but when I tried this command: python train.py --img 640 --cfg yolov5s.yaml --hyp hyp.scratch.yaml --batch 32 --epochs 100 --data road_sign_data.yaml --weights yolov5s.pt --workers 24 --name yolo_road_det

I got this error:

File "/home/UbuntuUser/.local/lib/python3.8/site-packages/torch/serialization.py", line 242, in __init__ super(_open_zipfile_reader, self).__init__(torch._C.PyTorchFileReader(name_or_buffer)) RuntimeError: [enforce fail at inline_container.cc:145] . PytorchStreamReader failed reading zip archive: failed finding central directory

Any idea, what is wrong and how to fix it?
