Morphological Distance Transform on Pytorch

I want to define function “scipy.ndimage.morphology.distance_transform_edt” in tensor computation.
It can be replaced by using “torch.from_numpy()” and above function, but it’s too slow for traning state.
Is there any implementation or replacement for this computation?
