Is your feature request related to a problem? Please describe.
shape checks such as

MONAI/monai/metrics/meandice.py

Lines 122 to 123 in 82ec2fe

	if y.shape != y_pred.shape:
	raise ValueError("y_pred and y should have same shapes.")

should provide more details about the current shapes for better usability.

raise ValueError(f"y_pred and y should have same shapes, got {y_pred.shape} and {y.shape}.")

would be great to review all the error messages... cc @Project-MONAI/core-reviewers

Hi @yiheng-wang-nv ,

Would you like to help double-check and enhance the error messages in our metrics?

Thanks.
