How to mark transformation a possible to chache

[jakubMitura14]

Hello I am using custom transform that extend MapTransform and smart cache dataset
The default behaviour is not to chache transform (and I fully agree with such decision !) Hovewer when I know that the ransform is not random I would like to mark it so the Cache dataset will understand it - How to achieve it ?

Hi @jakubMitura14, thanks for your interest! If your custom transform is randomized, just inherit the Randomizable. The CacheDataset will cache the transform if the transform is not randomized.

MONAI/monai/data/dataset.py

Lines 842 to 845 in 9eb513a

	for _transform in self.transform.transforms: # type:ignore
	# execute all the deterministic transforms
	if isinstance(_transform, Randomizable) or not isinstance(_transform, Transform):
	break

Hope it can help you, thanks!
