Strange Learning curve

Hello Roboflow Team and Community!

I noticed a weird jump along the X-axis (Epoch axis), which seems like it could be a bug. Is there any explanation?

UPD: the model behind this plots is Roboflow 3.0

Hello @asilvestrov thank you for flagging this! This indeed could be a bug on our end. Could you please provide a link to the training run where you experienced this?
Also is it ok if I add myself to your workspace to troubleshoot it faster?

Actually I was able to get the train run from the communication you sent to us, will take a look at it and get back in touch shortly.

@asilvestrov I found the issue causing this behavior, it is related to how we display epochs on our end. It is not critical and doesnโ€™t affect the training quality or model performance. But we will fix this display issue in the future. Thank you very much for reporting this!

@Matvei_Popov thank you!

I still have a question on this learning curve: there is a loss drop (Y axis) around 120 epoch. Iโ€™m reading that in YOLO models it might be caused by turning off advanced augmentantions such as Mosaic aug.

At the same time, iโ€™m using just basic augs (flips, rotations, whatever).
