calculate dice of different class separately

[YingdiZhang]

Thanks for the excellent work.
I am using MONAI for 3D multi-class segmentation task. When it comes to validation part， I want to calculate the dice metric of every class separately instead of all class together in the tutorial. I wonder how to achive that efficiently？

Hi @yingdiLee ,

Thanks for your interest here.
You can try to set the reduction arg of dice metric.

Thanks.
