Shape error for gradients/Sum_grad/Tile

[Oceania2018]

It throws error when run LogisticRegression example.

Shape must be rank 1 but is rank 2 for 'gradients/Sum_grad/Tile' (op: 'Tile') with input shapes: [1], [2].
System.Exception: Shape must be rank 1 but is rank 2 for 'gradients/Sum_grad/Tile' (op: 'Tile') with input shapes: [1], [2].

Dimension size must be evenly divisible by 10 but is 1 for 'gradients/add_grad/Reshape' (op: 'Reshape') with input shapes: [], [2] and with input tensors computed as partial shapes: input[1] = [?,10].

mul_grad is not correct, mssing shape.
