Returns locations of nonzero / true values in a tensor.
This operation returns the coordinates of true elements in `condition`. The coordinates are returned in a 2-D tensor where the first dimension (rows) represents the number of true elements, and the second dimension (columns) represents the coordinates of the true elements. Keep in mind, the shape of the output tensor can vary depending on how many true values there are in `condition`. Indices are output in row-major order.
For example:
# 'input' tensor is [[True, False]
# [True, False]]
# 'input' has two true values, so output has two coordinates.
# 'input' has rank of 2, so coordinates have two indices.
where(input) ==> [[0, 0],
[1, 0]]
# `condition` tensor is [[[True, False]
# [True, False]]
# [[False, True]
# [False, True]]
# [[False, False]
# [False, True]]]
# 'input' has 5 true values, so output has 5 coordinates.
# 'input' has rank of 3, so coordinates have three indices.
where(input) ==> [[0, 0, 0],
[0, 1, 0],
[1, 0, 1],
[1, 1, 1],
[2, 1, 1]]
# `condition` tensor is [[[1.5, 0.0]
# [-0.5, 0.0]]
# [[0.0, 0.25]
# [0.0, 0.75]]
# [[0.0, 0.0]
# [0.0, 0.01]]]
# 'input' has 5 nonzero values, so output has 5 coordinates.
# 'input' has rank of 3, so coordinates have three indices.
where(input) ==> [[0, 0, 0],
[0, 1, 0],
[1, 0, 1],
[1, 1, 1],
[2, 1, 1]]
# `condition` tensor is [[[1.5 + 0.0j, 0.0 + 0.0j]
# [0.0 + 0.5j, 0.0 + 0.0j]]
# [[0.0 + 0.0j, 0.25 + 1.5j]
# [0.0 + 0.0j, 0.75 + 0.0j]]
# [[0.0 + 0.0j, 0.0 + 0.0j]
# [0.0 + 0.0j, 0.01 + 0.0j]]]
# 'input' has 5 nonzero magnitude values, so output has 5 coordinates.
# 'input' has rank of 3, so coordinates have three indices.

Public Methods
public Output<TInt64> 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 Where create (Scope scope, Operand<? extends TType> condition)
Factory method to create a class wrapping a new Where operation.
Parameters
scope | current scope |

Returns
- a new instance of Where
