Other than the project file, nothing is read or written
using the hard disk.
gray_vol: A 3D numpy array with axes zyx
mask: A binary image where 0 means "no prediction necessary".
'None' can be given, which means "predict everything".
ilp_path: Path to the project file. ilastik also accepts a url to a DVID key-value, which will be downloaded and opened as an ilp
selected_channels: A list of channel indexes to select and return from the prediction results.
'None' can also be given, which means "return all prediction channels".
You may also return a *nested* list, in which case groups of channels can be
combined (summed) into their respective output channels.
For example: selected_channels=[0,3,[2,4],7] means the output will have 4 channels:
0,3,2+4,7 (channels 5 and 6 are simply dropped).
normalize: Renormalize all outputs so the channels sum to 1 everywhere.
That is, (predictions.sum(axis=-1) == 1.0).all()
Note: Pixels with 0.0 in all channels will be simply given a value of 1/N in all channels.
