Why is there `mega_core.trainer ERROR`?

[Dawn-LX]

mega_core.trainer ERROR: Iteration=4 || Image names used for training ('train/ILSVRC2015_VID_train_0003/ILSVRC2015_train_00839000/000255',) || targets Length=[0] (I have modified the error log infor to print the image file name)

In self.filter_annotation(), class VIDMEGADataset, we already have filtered out the images with len(objs) == 0

So Why this mega_core.trainer ERROR occurs ？ Has the target ( returned by VIDMEGADataset._get_train() ) been modified somewhere else ?

Looking forward to your answer

I also have the problem, have you solved it ?

It’s been a long time, I probably forgot my previous operation.

in fact I have modified the dataloader and i made some mistakes. in my modified dataloader, I reversed the width and height of class BoxList, and as for the gt_target, after target = target.clip_to_image, it will cause many bboxed outside the image and be clipped, thus result in targets Length=[0]

again, It’s been a long time, I probably forgot my previous operation, perhaps, when I use the original dataloader of MEGA ,it also occurs targets Length=[0], but the amount is much less than that using the dataloader modified by my above mistaken operation.

and, if you use the original dataloader of MAGE and also has this ERROR, then I don't konw why and I haven't solved this.
