tensör akışı:: işlem:: Katılmayı Azalt
#include <string_ops.h> Verilen boyutlar boyunca bir Tensör dizesini birleştirir.
Özet
Verilen şekil Tensörü içindeki boyutlar arasındaki dize birleşimini hesaplar [\\(d_0, d_1, ..., d_{n-1}\\)] . Giriş dizelerinin verilen ayırıcıyla birleştirilmesiyle oluşturulan yeni bir Tensör döndürür (varsayılan: boş dize). Negatif endeksler sondan geriye doğru sayılır; -1 n - 1 eşdeğerdir. Endeksler belirtilmemişse, n - 1 0 kadar tüm boyutlarda birleşir.
Örneğin:
# 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"
Argümanlar:
- kapsam: Bir Kapsam nesnesi
- Girişler: Birleştirilecek giriş. Tüm azaltılmış endeksler sıfırdan farklı bir boyuta sahip olmalıdır.
- reduction_indices: Azaltılacak boyutlar. Boyutlar belirtilen sıraya göre küçültülür.
reduction_indices atlamak [n-1, n-2, ..., 0] geçirmeye eşdeğerdir. -n -1 kadar negatif indeksler desteklenir.
İsteğe bağlı özellikler (bkz. Attrs ):
- keep_dims:
True ise, uzunluğu 1 olan azaltılmış boyutları koruyun. - ayırıcı: Birleştirme sırasında kullanılacak ayırıcı.
İade:
-
Output : keep_dims bağlı olarak küçültülmüş boyutların kaldırıldığı veya 1 ayarlandığı girişin şekline eşit bir şekle sahiptir.

Returns a new [Tensor](/versions/r2.2/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/r2.2/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- inputs: The input to be joined. [All](/versions/r2.2/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/r2.2/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/r2.2/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): Has shape equal to that of
