#include <string_ops.h>
Menggabungkan Tensor string pada dimensi tertentu.
Ringkasan
Menghitung gabungan string lintas dimensi dalam string tertentu Tensor bentuk [\\(d_0, d_1, ..., d_{n-1}\\)]
. Mengembalikan Tensor baru yang dibuat dengan menggabungkan string input dengan pemisah yang diberikan (default: string kosong). Indeks negatif dihitung mundur dari akhir, dengan -1
setara dengan n - 1
. Jika indeks tidak ditentukan, gabungkan seluruh dimensi mulai dari n - 1
hingga 0
.
Misalnya:
# tensor `a` is [["a", "b"], ["c", "d"]]
tf.reduce_join(a, 0) ==> ["ac", "bd"]
tf.reduce_join(a, 1) ==> ["ab", "cd"]
tf.reduce_join(a, -2) = tf.reduce_join(a, 0) ==> ["ac", "bd"]
tf.reduce_join(a, -1) = tf.reduce_join(a, 1) ==> ["ab", "cd"]
tf.reduce_join(a, 0, keep_dims=True) ==> [["ac", "bd"]]
tf.reduce_join(a, 1, keep_dims=True) ==> [["ab"], ["cd"]]
tf.reduce_join(a, 0, separator=".") ==> ["a.c", "b.d"]
tf.reduce_join(a, [0, 1]) ==> "acbd"
tf.reduce_join(a, [1, 0]) ==> "abcd"
tf.reduce_join(a, []) ==> [["a", "b"], ["c", "d"]]
tf.reduce_join(a) = tf.reduce_join(a, [1, 0]) ==> "abcd"
Argumen:
- ruang lingkup: Objek Lingkup
- inputs : Input yang akan digabungkan. Semua indeks yang dikurangi harus berukuran bukan nol.
- reduksi_indeks: Dimensi yang akan dikurangi. Dimensi dikurangi dalam urutan yang ditentukan. Menghilangkan
reduction_indices
sama dengan meneruskan [n-1, n-2, ..., 0]
. Indeks negatif dari -n
hingga -1
didukung.
Atribut opsional (lihat Attrs
):
- keep_dims: Jika
True
, pertahankan dimensi yang diperkecil dengan panjang 1
. - pemisah: Pemisah yang digunakan saat bergabung.
Pengembalian:
-
Output
: Memiliki bentuk yang sama dengan input dengan pengurangan dimensi dihapus atau disetel ke 1
bergantung pada keep_dims
.

Returns a new [Tensor](/versions/r2.0/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) created by joining the input strings with the given separator (default: empty string). Negative indices are counted backwards from the end, with `-1` being equivalent to `n - 1`. If indices are not specified, joins across all dimensions beginning from `n - 1` through `0`.\n\nFor example:\n\n\n```mysql\n# tensor `a` is [[\"a\", \"b\"], [\"c\", \"d\"]]\ntf.reduce_join(a, 0) ==\u003e [\"ac\", \"bd\"]\ntf.reduce_join(a, 1) ==\u003e [\"ab\", \"cd\"]\ntf.reduce_join(a, -2) = tf.reduce_join(a, 0) ==\u003e [\"ac\", \"bd\"]\ntf.reduce_join(a, -1) = tf.reduce_join(a, 1) ==\u003e [\"ab\", \"cd\"]\ntf.reduce_join(a, 0, keep_dims=True) ==\u003e [[\"ac\", \"bd\"]]\ntf.reduce_join(a, 1, keep_dims=True) ==\u003e [[\"ab\"], [\"cd\"]]\ntf.reduce_join(a, 0, separator=\".\") ==\u003e [\"a.c\", \"b.d\"]\ntf.reduce_join(a, [0, 1]) ==\u003e \"acbd\"\ntf.reduce_join(a, [1, 0]) ==\u003e \"abcd\"\ntf.reduce_join(a, []) ==\u003e [[\"a\", \"b\"], [\"c\", \"d\"]]\ntf.reduce_join(a) = tf.reduce_join(a, [1, 0]) ==\u003e \"abcd\"\n```\n\n\u003cbr /\u003e\n\nArguments:\n\n- scope: A [Scope](/versions/r2.0/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- inputs: The input to be joined. [All](/versions/r2.0/api_docs/cc/class/tensorflow/ops/all#classtensorflow_1_1ops_1_1_all) reduced indices must have non-zero size.\n- reduction_indices: The dimensions to reduce over. Dimensions are reduced in the order specified. Omitting `reduction_indices` is equivalent to passing `[n-1, n-2, ..., 0]`. Negative indices from `-n` to `-1` are supported.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.0/api_docs/cc/struct/tensorflow/ops/reduce-join/attrs#structtensorflow_1_1ops_1_1_reduce_join_1_1_attrs)):\n\n- keep_dims: If `True`, retain reduced dimensions with length `1`.\n- separator: The separator to use when joining.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.0/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): Has shape equal to that of the input with reduced dimensions removed or set to `1` depending on `keep_dims`.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n|
