MeanDice ( monai.handlers.mean_dice) is not updating in multi-label segmentation task

[saruarlive]

Hi, @Nic-Ma et al,

Could you kindly provide a simple toy example using the meandice handler in multi-label segmentation task?
I asked that before that the meandice score is not updating in the training log. It works while testing on random pred/target

Hi @saruarlive ,

If you want to compute MeanDice in ignite program or MONAI engines, you can refer to this example:
https://github.com/Project-MONAI/tutorials/blob/master/modules/engines/unet_training_dict.py#L137
If you just want to compute MeanDice metrics in multi-labels task in regular PyTorch program, you can refer to:

Thanks.
