요약
indices
모든 차원(보통 0-D 또는 1-D)의 정수 텐서여야 합니다. params.shape[:axis] + indices.shape + params.shape[axis + 1:]
형태의 출력 텐서를 생성합니다. 여기서:
# Scalar indices (output is rank(params) - 1).
output[a_0, ..., a_n, b_0, ..., b_n] =
params[a_0, ..., a_n, indices, b_0, ..., b_n]
# Vector indices (output is rank(params)).
output[a_0, ..., a_n, i, b_0, ..., b_n] =
params[a_0, ..., a_n, indices[i], b_0, ..., b_n]
# Higher rank indices (output is rank(params) + rank(indices) - 1).
output[a_0, ..., a_n, i, ..., j, b_0, ... b_n] =
params[a_0, ..., a_n, indices[i, ..., j], b_0, ..., b_n]

CPU에서 범위를 벗어난 인덱스가 발견되면 오류가 반환됩니다. GPU에서는 범위를 벗어난 인덱스가 발견되면 해당 출력 값에 0이 저장됩니다.

인수:
- 범위: 범위 개체
- params: 값을 수집할 텐서입니다. 최소한 순위
axis + 1
이어야 합니다. - 인덱스: 인덱스 텐서.
[0, params.shape[axis])
범위 내에 있어야 합니다. - axis:
indices
수집할 params
의 축입니다. 기본값은 첫 번째 차원입니다. 음수 인덱스를 지원합니다.
