			abstract type ModelVariant

A ModelVariant handles loading a model, optionally with pretrained weights and transforming it so that it can be used for specific learning tasks.

are subblocks (see issubblock) of blocks = (xblock, yblock).

Interface

• compatibleblocks (variant) returns a tuple (xblock, yblock) of BlockLike that are compatible with the model. This means that a variant can be used for a task with input and output blocks blocks, if issubblock (blocks, compatibleblocks(variant)).

• loadvariant (::ModelVariant, xblock, yblock, checkpoint; kwargs...) loads a model compatible with block instances xblock and yblock, with (optionally) weights from checkpoint.
