Detailed Description

A helper class to indicate that the operator does not need gradient computation.

Use the macro NO_GRADIENT to register operators that do not have gradients. Note that this is different fron SHOULD_NOT_DO_GRADIENT: the latter means that the gradient computation should not flow through it at all, and throws an error if it is called.
