Deconvolution is super slow

[kitovyj]

Hello all.

Thank you for a great tool. I wonder, is there any way to speed up the computations? Layer deconvolution takes ~7 seconds in my case and I want to calculate deconvolutions for around ~10k examples, the network is of 7 layers.

You could run the experiment in batches. Using a large batch size would be useful here to speed up the computations. We haven't experimented extensively with this, but the outputs of a batch would get written to disk together in an image. Let us know if this helps.

Hmm, when I feed a batch with multiple inputs, the tool still generates a single image for each layer... I don't understand the principle here.

Hi @kitovyj We are working on this. We'll roll out a version where you should be able to insert multiple images simultaneously. You are right - we revisited the code and in its current state it would return just the first image output.
