Question

How can I change the hyp of mosaic_min_ratio when training? I found that there's not the hyp. Should I download all the codes, deactivate the python-envs, and change it in the funcion? Is there any easier way to set the parameter in "yolo train model=.pt data=.yaml mosaic=1"

I found that every time in train_batch.jpg, some boxes with too small size also exist, which should be ignored

Hello,

Thank you for reaching out! You can indeed adjust the mosaic_min_ratio hyperparameter without needing to download and modify the source code directly. Instead, you can specify this parameter in your training command using the --hyp argument to point to a custom YAML file where you define your hyperparameters.

Here's a step-by-step guide:

1. Create a Custom Hyperparameters File: Create a YAML file (e.g., custom_hyp.yaml) and include the mosaic_min_ratio parameter along with any other hyperparameters you wish to customize. For example:

   mosaic_min_ratio: 0.2  # Adjust this value as needed
   # Add other hyperparameters here

2. Run the Training Command: Use the --hyp argument to specify your custom hyperparameters file in the training command:

   yolo train model=your_model.pt data=your_data.yaml hyp=custom_hyp.yaml

This approach allows you to easily modify hyperparameters without altering the core codebase or environment.

Additionally, if you haven't already, please ensure you are using the latest version of the Ultralytics packages to benefit from the latest features and bug fixes.

If you encounter any further issues or have more questions, feel free to ask. Happy training! 🚀
