RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:0 and cpu!

I encountered the following error while reproducing your code：RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:0 and cpu!

The specific details are as follows：
Plotting labels...
Image sizes 640 train, 640 val
Using 8 dataloader workers
Logging results to runs/train/exp
Starting training for 300 epochs...

 Epoch   gpu_mem       box       obj       cls    labels  img_size

May I ask if there is a good and effective solution，thanks.

Requirements

Python>=3.6.0 with all requirements.txt installed including PyTorch>=1.7. To get started:

$ git clone https://github.com/ultralytics/yolov5
$ cd yolov5
$ pip install -r requirements.txt

Environments

YOLOv5 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):

• Google Colab and Kaggle notebooks with free GPU:
• Google Cloud Deep Learning VM. See GCP Quickstart Guide

how about check your device?it's seems that you have a gpu and a cup ,maybe your device get wrong
