self.embed_model = BasicUNetEncoder(3, 1, 2, [64, 64, 128, 256, 512, 64])
self.model = BasicUNetDe(3, 14, 13, [64, 64, 128, 256, 512, 64]

why the embed_model not be BasicUNetEncoder(3, 1, 13, [64, 64, 128, 256, 512, 64])
2.
why use the resample_img(), and if I run on my own dataset, in which case I should use it.

1. The third parameter of the embed_model is useless, because embed_model is an encoder which only extract the features of image.
2. 3D images need to be resampled to the same spacing, and you also need to resize the model's outputs to the original size in the testing phase.
