Hello @zaleslaw , I am learning about Tensorflow for Java and doing some codes with math operations between two tensors with more than one dimension, do you have interest in check them out?

Hello @zaleslaw, here it is https://github.com/gustavo-ren/java-tensor-math/tree/master I implemented the four basic ops on array Tensors, feel free to tell me what you think.

Hi @zaleslaw, in second task, copy to/from tensor means from Java array to tensor and from tensor to Java array?
