Hello Juha! Thanks for the vote of confidence 
So any bindings for Tensorflow can only be written around the C API, which is publicly exposed by Google. Unfortunately, they have not added Training functionality to the C API yet. So we will have to wait and see when they do that and then we can support it in Tensorflex too. Also, most other Tensorflow bindings, such as the ones officially written for Golang, only support Inference.
