텐서플로우:: 작전:: 어디에3
#include <math_ops.h> condition 에 따라 x 또는 y 에서 요소를 선택합니다.
요약
x 및 y 텐서는 모두 동일한 모양을 가져야 하며 출력도 해당 모양을 갖습니다.
x 와 y 가 스칼라인 경우 condition 텐서는 스칼라여야 합니다. x 및 y 가 벡터 이상의 순위인 경우 condition 은 스칼라( x 의 첫 번째 차원과 크기가 일치하는 벡터)이거나 x 와 모양이 동일해야 합니다.
condition 텐서는 각 요소의 값을 기반으로 출력의 해당 요소/행을 x (true인 경우) 또는 y (false인 경우)에서 가져와야 하는지 여부를 선택하는 마스크 역할을 합니다.
condition 벡터이고 x 및 y 더 높은 순위 행렬인 경우 x 및 y 에서 복사할 행(외부 차원)을 선택합니다. condition x 및 y 와 모양이 동일한 경우 x 및 y 에서 복사할 요소를 선택합니다.
예를 들어:
# 'condition' tensor is [[True, False]
# [False, True]]
# 't' is [[1, 2],
# [3, 4]]
# 'e' is [[5, 6],
# [7, 8]]
select(condition, t, e) # => [[1, 6], [7, 4]]
# 'condition' tensor is [True, False]
# 't' is [[1, 2],
# [3, 4]]
# 'e' is [[5, 6],
# [7, 8]]
select(condition, t, e) ==> [[1, 2],
[7, 8]]
Arguments:
- scope: A Scope object
- x: = A
Tensor which may have the same shape as condition. If condition is rank 1, x may have higher rank, but its first dimension must match the size of condition.
- y: = A
Tensor with the same type and shape as x.

If `x` and `y` are vectors or higher rank, then `condition` must be either a scalar, a vector with size matching the first dimension of `x`, or must have the same shape as `x`.\n\nThe `condition` tensor acts as a mask that chooses, based on the value at each element, whether the corresponding element / row in the output should be taken from `x` (if true) or `y` (if false).\n\nIf `condition` is a vector and `x` and `y` are higher rank matrices, then it chooses which row (outer dimension) to copy from `x` and `y`. If `condition` has the same shape as `x` and `y`, then it chooses which element to copy from `x` and `y`.\n\nFor example:\n\n\n```text\n# 'condition' tensor is [[True, False]\n# [False, True]]\n# 't' is [[1, 2],\n# [3, 4]]\n# 'e' is [[5, 6],\n# [7, 8]]\nselect(condition, t, e) # =\u003e [[1, 6], [7, 4]]\n```\n\n\u003cbr /\u003e\n\n\n```text\n# 'condition' tensor is [True, False]\n# 't' is [[1, 2],\n# [3, 4]]\n# 'e' is [[5, 6],\n# [7, 8]]\nselect(condition, t, e) ==\u003e [[1, 2],\n [7, 8]]\n```\n\n\u003cbr /\u003e\n\n\n````gdscript\n \n Arguments:\n \n- scope: A /versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope object\n\n \n- x: = A /versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor which may have the same shape as condition.
