flujo tensor:: operaciones:: ReunirV2 #include <array_ops.h> Reúna cortes del axis de params según los indices .
Resumen indices deben ser un tensor entero de cualquier dimensión (normalmente 0-D o 1-D). Produce un tensor de salida con forma params.shape[:axis] + indices.shape + params.shape[axis + 1:] donde:
# 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]
Tenga en cuenta que en la CPU, si se encuentra un índice fuera de límite, se devuelve un error. En GPU, si se encuentra un índice fuera de límite, se almacena un 0 en el valor de salida correspondiente.
