> Whether there is an annotation error in the training label?

When browsing the dataset, a small number of image labels are found to be abnormal.
For example:
train/G10_S29_C4_E02_T20220304114916210/id_28/890_97.jpg 1
train/G06_S25_C1_E05_T20220228163246541/id_0/140_0.jpg 0

Please confirm.

The labels of the dataset are manually marked. There are some wrong labels, but the number is very small.
