Data Augmentation

I am trying to randomly crop tensors to a specific size. I could see that there exists Raw.RandomCrop but it gives the error

Op RandomCrop is not available in GraphDef version 29

That is old legacy code from an early version of TensorFlow that no longer exists in mainline (was moved to python/keras). If you would like a swift version, check out lines 36-56 of main.swift in my imagenette demo:

ps an issue you could tackle:

if you’re not interested, I would be happy to convert your demo over!


Thanks @asparagui I ended up using a similar approach but where I don’t loop over all the elements of the batch but rather using the same crop for the whole batch.

ps: I think somebody is already working on the neural style stuff. Which demo you mean ?

doh, got you mixed up with somebody else!
