View the 2D slices of 3D data.

[jiashizuo]

Hello, I would like to know how the slicing of 3D data is done when training a 2D model. For example, can I view these slices after the training is completed? I noticed that the data is stored in 3D format. Is there an ID for the data slices (I have not found the location of this) that would allow me to view these 2D slices? I also want to know along which axis the 3D data is sliced. Thank you so much.
