Argument:

• Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.)
• Input input: The default value to produce when output is not fed.
• PartialTensorShape shape: The (possibly partial) shape of the tensor.

Output:

• Output output : Output object of PlaceholderWithDefault class object.

Result:

• std::vector(Tensor) result_output: A placeholder tensor that defaults to input if it is not fed.

Using Method

※ placeholder에 input값을 넣어서 feedtype블럭을 사용하지 않고도 초기화를 할 수 있다. 다른 연산에서 나온 output값을 input에 연결하여 다른 블럭들에 사용 할 수 있다.
