I created a dataset of 200 images through the ultralytics platform, which contained 6 categories. Then I trained a model named best.pt. Subsequently, I wanted to use the best.pt model for smart annotation, so I added another 1000 images to the original dataset. I carried out the annotation task in this way last week, but now I’m receiving the message: “This model’s classes do not match the dataset.” I can confirm that my categories have not been modified in any way. And everything was carried out normally last week. I hope to receive a response. Thank you.

Thanks for reporting.
We are looking into it.

@jinwei_li should be fixed now, can you please try again and let us know if this is solved for you?
I validate the fix I trained a model on an existing dataset, then went back to the dataset and deleted a few annotations and use auto annotation with the model I’d just trained and it’s working correctly for me.
