tensorflow::ops::Placeholder
#include <array_ops.h>
A placeholder op for a value that will be fed into the computation.
Summary
N.B. This operation will fail with an error if it is executed. It is intended as a way to represent a value that will always be fed, and to provide attrs that enable the fed value to be checked at runtime.
Arguments:
- scope: A Scope object
- dtype: The type of elements in the tensor.
Optional attributes (see Attrs
):
- shape: (Optional) The shape of the tensor. If the shape has 0 dimensions, the shape is unconstrained.
Returns:
-
Output
: A placeholder tensor that must be replaced using the feed mechanism.
