aliran tensor:: operasi:: Penghalang
#include <data_flow_ops.h>
Mendefinisikan penghalang yang bertahan di berbagai eksekusi grafik.
Ringkasan
Penghalang mewakili peta nilai kunci, di mana setiap kunci adalah string, dan setiap nilai adalah tupel tensor.
Pada saat runtime, penghalang berisi elemen 'lengkap' dan 'tidak lengkap'. Elemen lengkap telah menentukan tensor untuk semua komponen tupel nilainya, dan dapat diakses menggunakan BarrierTakeMany . Elemen yang tidak lengkap memiliki beberapa komponen yang tidak terdefinisi dalam tupel nilainya, dan dapat diperbarui menggunakan BarrierInsertMany .
Argumen:
- ruang lingkup: Objek Lingkup
- komponen_tipe: Jenis setiap komponen dalam suatu nilai.
Atribut opsional (lihat Attrs
):
- bentuk : Bentuk setiap komponen dalam suatu nilai. Setiap bentuk harus bernilai 1 pada dimensi pertama. Panjang attr ini harus sama dengan panjang komponen_tipe.
- kapasitas: Kapasitas penghalang. Kapasitas defaultnya adalah MAX_INT32, yang merupakan kapasitas terbesar dari antrean yang mendasarinya.
- wadah: Jika tidak kosong, pembatas ini ditempatkan pada wadah yang diberikan. Jika tidak, wadah default akan digunakan.
- shared_name: Jika tidak kosong, penghalang ini akan dibagikan dengan nama tertentu di beberapa sesi.
Pengembalian:

Output
: Pegangan untuk penghalang.

A complete element has defined tensors for all components of its value tuple, and may be accessed using [BarrierTakeMany](/versions/r2.3/api_docs/cc/class/tensorflow/ops/barrier-take-many#classtensorflow_1_1ops_1_1_barrier_take_many). An incomplete element has some undefined components in its value tuple, and may be updated using [BarrierInsertMany](/versions/r2.3/api_docs/cc/class/tensorflow/ops/barrier-insert-many#classtensorflow_1_1ops_1_1_barrier_insert_many).\n\nArguments:\n\n- scope: A [Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- component_types: The type of each component in a value.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/barrier/attrs#structtensorflow_1_1ops_1_1_barrier_1_1_attrs)):\n\n- shapes: The shape of each component in a value. Each shape must be 1 in the first dimension. The length of this attr must be the same as the length of component_types.\n- capacity: The capacity of the barrier. The default capacity is MAX_INT32, which is the largest capacity of the underlying queue.\n- container: If non-empty, this barrier is placed in the given container. Otherwise, a default container is used.\n- shared_name: If non-empty, this barrier will be shared under the given name across multiple sessions.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): The handle to the barrier.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n|
