Mar 25, 2021 · (which will be subtracted to 0 and 1 in class OxfordPets(keras.utils.Sequence):) Question is how do I get the IoU metric of a single class (e.g 1)? I have tried different metrics suggested by Stack Overflow but most of suggest using MeanIoU which I tried but I have gotten nan loss as a result. Here is an example of a mask after using autocontrast.
