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

    dtype, shape=None, name=None

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.


  • dtype: A tf.DType. The type of elements in the tensor.
  • shape: An optional tf.TensorShape or list of ints. Defaults to None. (Optional) The shape of the tensor. If the shape has 0 dimensions, the shape is unconstrained.
  • name: A name for the operation (optional).
