Hey,
I think it should be possible to do it only with the Keras API. Then
it's fully portable, but the GPU stuff for Tensorflows is getting tricky
(or I haven't found an easy solution yet).
Keras has all the pooling and convolution sutff that you need, so
probably give it a try. Theano has really some advantages!
Greetings,
Stefan
