Reshape

public final class Reshape

Reshapes a tensor.

Given `tensor`, this operation returns a tensor that has the same values as `tensor` with shape `shape`.

If one component of 1-D tensor `shape` is the special value -1, the size of that dimension is computed so that the total size remains constant. In particular, a `shape` of `[-1]` flattens into 1-D. At most one component of `shape` may be unknown.

The `shape` must be 1-D and the operation returns a tensor with shape `shape` filled with the values of `tensor`. In this case, the number of elements implied by `shape` must be the same as the number of elements in `tensor`.

It is an error if `shape` is not 1-D.

For example: 

# tensor 't' is [1, 2, 3, 4, 5, 6, 7, 8, 9]
 # tensor 't' has shape [9]
 reshape(t, [3, 3]) ==> [[1, 2, 3],
                         [4, 5, 6],
                         [7, 8, 9]]
 
 # tensor 't' is [[[1, 1], [2, 2]],
 #                [[3, 3], [4, 4]]]
 # tensor 't' has shape [2, 2, 2]
 reshape(t, [2, 4]) ==> [[1, 1, 2, 2],
                         [3, 3, 4, 4]]
 
 # tensor 't' is [[[1, 1, 1],
 #                 [2, 2, 2]],
 #                [[3, 3, 3],
 #                 [4, 4, 4]],
 #                [[5, 5, 5],
 #                 [6, 6, 6]]]
 # tensor 't' has shape [3, 2, 3]
 # pass '[-1]' to flatten 't'
 reshape(t, [-1]) ==> [1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6]
 
 # -1 can also be used to infer the shape
 
 # -1 is inferred to be 9:
 reshape(t, [2, -1]) ==> [[1, 1, 1, 2, 2, 2, 3, 3, 3],
                          [4, 4, 4, 5, 5, 5, 6, 6, 6]]
 # -1 is inferred to be 2:
 reshape(t, [-1, 9]) ==> [[1, 1, 1, 2, 2, 2, 3, 3, 3],
                          [4, 4, 4, 5, 5, 5, 6, 6, 6]]
 # -1 is inferred to be 3:
 reshape(t, [ 2, -1, 3]) ==> [[[1, 1, 1],
                               [2, 2, 2],
                               [3, 3, 3]],
                              [[4, 4, 4],
                               [5, 5, 5],
                               [6, 6, 6]]]
 
 # tensor 't' is [7]
 # shape `[]` reshapes to a scalar
 reshape(t, []) ==> 7

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "Reshape"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the 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 Reshape<T> create (Scope scope, Operand<T> tensor, Operand<? extends TNumber> shape)

Factory method to create a class wrapping a new Reshape operation.

Parameters
scope current scope
shape Defines the shape of the output tensor.
Returns
  • a new instance of Reshape
