@karllessard the `ops.pb` conflict is because I moved the `nn.raw `ops to `nn`, and moved the higher level `nn` ops to `framework`. This is a generated file so I am...

I added a parameter to `Optimizer.optimize` to pass in the trainable variables, now I get the error: ``` org.tensorflow.exceptions.TensorFlowException: No gradient defined for op: Cast. Please see https://www.tensorflow.org/code/tensorflow/cc/gradients/README.md for instructions...

I wonder if there are more of these?

@rnett Yes, I saw that last week. However, it turns out I was passing the wrong arguments to my loss operation as I should have included the trainable variables in...

The Python and C/C++ versions are totally different than the Python implementation for v1, I don't see any similarity other than the fact that they calculate gradients. I am wondering...

@cowwoc OK, one problem I have is I need to work with my latest version of the xxxSession classes that I am using for Models and Layers, I assume you...

I understand that, but I need to test with my latest code first.

Will `Operand.dataToString()` work in Graph mode with out first doing a try catch? ``` try (Tensor tensor = session.runner().fetch(input).run().get(0)) { tensor.dataToString() } ```

Would we want the printed values enclosed in braces `( {} )` rather than square brackets` ( [] `}. Braces make it easier to copy and past into Java code.

I think we should pattern the output after` java.util.Arrays.deepToString()`, which takes us back to brackets with commas. ``` float[][][] f = new float[][][] { {{1,2}, {3,4}}, {{5, 6}, {7, 8}},...
