# tensorflow::ops::PlaceholderWithDefault Class Reference

# tensorflow::
ops::
PlaceholderWithDefault

`
#include <array_ops.h>
`


A placeholder op that passes through
`
input
`
when its output is not fed.

## Summary


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- input: The default value to produce when `
  output
  ` is not fed.
- shape: The (possibly partial) shape of the tensor.

<br />


Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` : A placeholder tensor that defaults to `
  input
  ` if it is not fed.
