I'm getting this error while evaluating the model.
As mentioned in the previous issue i reinstalled matplotlib, but i'm getting this error. Can you please help me to resolve this issue???

This probably does not have to do with the model, since it seems your problem comes from the fact that it asks you for binary data and you may be giving it, multi-class data maybe?

It is because the hausdorff metric. One of the mask your model predict is maybe all zero.
