AssertionError: Label class 33 exceeds nc=3 in ././models/yolov5s.yaml. Correct your labels or your model.

[sarj7]

i'm getting this error while training yolov5 on custom dataset. i have tried to resolve this error by following this thread. i have made sure that i have nc = 3 in dataset.yaml file as well as nc = 3 in yolov5s.yaml file as well.

i deleted the cache file as well. i've also made sure that .txt label file for each individual image has classes as 0,1 or 2. i don't where does this model picks number of classes = 33.

please help!

@sarj7 the error message is self explanatory. Your labels contain classes up to 33, which is about 30 more classes than you've stated in your data.yaml.
