PreventGradient
#include <array_ops.h>
An identity op that triggers an error if a gradient is requested.
Summary
When executed in a graph, this op outputs its input tensor as-is.
When building ops to compute gradients, the TensorFlow gradient system will return an error when trying to lookup the gradient of this op, because no gradient must ever be registered for this function. This op exists to prevent subtle bugs from silently returning unimplemented gradients in some corner cases.
Args:
- scope: A Scope object
- input: any tensor.
Optional attributes (see
Attrs
):
- message: Will be printed in the error when anyone tries to differentiate this operation.
Returns:
-
Output
: the same input tensor.
