| ### PR Best Practices | |
| To ensure your work is integrated smoothly, please: | |
| - ✅ Make sure your PR is **up-to-date** with the `ultralytics/yolov5` `master` branch. If your branch is behind, update it using the 'Update branch' button or by running `git pull` and `git merge master` locally. | |

| - ✅ Ensure all YOLO Continuous Integration (CI) **checks are passing**. | |

| ## 🐛 Submitting a Bug Report | |
| If you encounter an issue with YOLO, please submit a bug report! | |
| To help us investigate, we need to be able to reproduce the problem. Follow these guidelines to provide what we need to get started: | |
| When asking a question or reporting a bug, you'll get better help if you provide **code** that others can easily understand and use to **reproduce** the issue. This is known as a [minimum reproducible example](https://docs.ultralytics.com/help/minimum-reproducible-example/). Your code should be: | |
| - ✅ **Minimal** – Use as little code as possible that still produces the issue | |
| - ✅ **Complete** – Include all parts needed for someone else to reproduce the problem | |
| - ✅ **Reproducible** – Test your code to ensure it actually reproduces the issue | |
| Additionally, for [Ultralytics](https://www.ultralytics.com/) to assist you, your code should be: | |
| - ✅ **Current** – Ensure your code is up-to-date with the latest [master branch](https://github.com/ultralytics/yolov5/tree/master). Use `git pull` or `git clone` to get the latest version and confirm your issue hasn't already been fixed. | |
| - ✅ **Unmodified** – The problem must be reproducible without any custom modifications to the repository. [Ultralytics](https://www.ultralytics.com/) does not provide support for custom code ⚠️. | |
| If your issue meets these criteria, please close your current issue and open a new one using the 🐛 **Bug Report** [template](https://github.com/ultralytics/yolov5/issues/new/choose), including your [minimum reproducible example](https://docs.ultralytics.com/help/minimum-reproducible-example/) to help us diagnose your problem. | |
