👋 Hello @YounghoJo01, thank you for reaching out and your interest in YOLOv5 🚀!
It looks like you've encountered a runtime error while working with tensor dimensions. Don't worry, an Ultralytics engineer will assist you shortly. In the meantime, could you please provide a minimum reproducible example (MRE) to help us better understand and debug the issue? This should include any relevant code snippets and specific configurations you’re using.
To ensure everything is set up correctly, please check that your environment meets the following requirements:
