Bug

I tried to run the training app of yours on my Window machine. it has just loaded some stuffs, moving stuffs around, a few caches... then it crashed.

👋 Hello @suws0501, thank you for reaching out about your issue with YOLOv5 🚀! It looks like you're encountering a "Memory Error" while running training on your Windows machine.

As this seems to be a 🐛 Bug Report, could you please provide a minimum reproducible example to help us understand the problem better? This should include the exact command you're running along with any modifications you've made to the code or configuration.

In the meantime, please ensure your system meets the following requirements:

• Python>=3.8.0 with all necessary packages installed, including PyTorch>=1.8.
• Ensure your environment is properly set up for YOLOv5, and consider using a machine with greater memory if possible.

For execution environments, YOLOv5 can typically be run on multiple verified setups such as cloud platforms or with Docker to alleviate local resource constraints.

This is an automated response, but an Ultralytics engineer will look into your situation soon. In the meantime, feel free to add any additional information that might help us assist you. 😊
