mosaic ratio or stop mosaic epochs

[X] I have searched the YOLOv5 issues and discussions and found no similar questions.

Question

I want to set up mosaic ratio . For example ,I train 300 epochs ,the first 270 epochs I want to train with mosaic , and the last 30 epochs I don't want to train with mosaic . How should I do. I have experienced on other models ,the results shows that this way could improve the mAP.

@Jad-Goh there is no hyperparameter scheduling in place currently, but you might be able to use the same method here on L309 to update dataset properties:

Although I don't understand ,thanks a lot！I have a stupid method .

很笨的一个办法，这个办法我还没有具体操作，想法是这样的：假如我要训练300个epoch，我自己手动看着，到了290个epoch的时候，我手动停止，然后手动更改run文件夹里面的opt.yaml文件的hyp路径（或者直接改这个文件的mosaic参数），然后继续训练剩下的10个epoch。

好的，谢谢你
