Placeholder

A placeholder op for a value that will be fed into the computation.
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.

Public Methods
public
Output<T>
asOutput
()
Returns the symbolic handle of a tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is
used to obtain a symbolic handle that represents the computation of the input.
public
static
Placeholder<T>
create
(Scope scope, Class<T> dtype, Options... options)
Factory method to create a class wrapping a new Placeholder operation.
Parameters
| scope |
current scope |
| dtype |
The type of elements in the tensor. |
| options |
carries optional attributes values |
Returns
- a new instance of Placeholder
public
Output<T>
output
()
A placeholder tensor that must be replaced using the feed mechanism.
Parameters
| shape |
(Optional) The shape of the tensor. If the shape has 0 dimensions, the
shape is unconstrained.
