I am trying to train a model for Lung Tumor segmentation but the dice values and the model accuracy is 0. Any way of solving this problem?

Hi @A_By,

It isn’t easy to help without dataset details and steps you follow.  
I’d suggest opening a discussion on the MONAI Label repository ([Project-MONAI/MONAILabel · Discussions · GitHub](https://github.com/Project-MONAI/MONAILabel/discussions)) with more details about the steps you followed for training and the dataset you are using.
