tensorflow::ops::Placeholder

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.

Args:

• 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.
