aliran tensor:: operasi:: Variabel
#include <state_ops.h>
Memegang status dalam bentuk tensor yang bertahan di seluruh langkah.
Ringkasan
Menghasilkan referensi ke status tensor sehingga dapat dibaca atau dimodifikasi. TODO(zhifengc/mrry): Menambahkan penunjuk ke dokumen yang lebih detail tentang status berbagi di tensorflow.
Argumen:
- ruang lingkup: Objek Lingkup
- bentuk : Bentuk tensor variabel.
- dtype: Jenis elemen dalam tensor variabel.
Atribut opsional (lihat Attrs
):
- container: Jika tidak kosong, variabel ini ditempatkan di container yang diberikan. Jika tidak, wadah default akan digunakan.
- shared_name: Jika tidak kosong, variabel ini diberi nama dalam bucket yang diberikan dengan shared_name ini. Jika tidak, nama node akan digunakan sebagai gantinya.
Pengembalian:
-
Output
: Referensi ke tensor variabel.
