Description

I am trying to integrate Differential Privacy in my code, but the code is working fine only when I am using microbatch size as 1, other than that it is throwing the error. I even tried keeping it equal to the batch size. But the error is still not resolved.

EXACT ERROR:
ValueError: Dimension size must be evenly divisible by 50 but is 1 for '{{node Reshape}} = Reshape[T=DT_FLOAT, Tshape=DT_INT32](sparse_categorical_crossentropy/weighted_loss/value, Reshape/shape)' with input shapes: [], [2] and with input tensors computed as partial shapes: input[1] = [50,?].

Research direction

Start by reproducing the reported ValueError from the Differential Privacy integration, comparing the working microbatch size of 1 with larger values and checking the batch-size configuration. Trace the reported Reshape and weighted-loss operations to identify which dimension is expected to be divisible by 50. Done means the integration works with the intended microbatch size without the reshape error.
