aliran tensor:: operasi:: Cumprod
#include <math_ops.h> Hitung produk kumulatif tensor x sepanjang axis .
Ringkasan
Secara default, operasi ini menjalankan cumprod inklusif, yang berarti elemen pertama masukan identik dengan elemen pertama keluaran:
tf.cumprod([a, b, c]) # => [a, a * b, a * b * c]
Dengan menyetel kwarg exclusive ke True , cumprod eksklusif akan dijalankan:
tf.cumprod([a, b, c], exclusive=True) # => [1, a, a * b]
Dengan mengatur kwarg reverse ke True , cumprod dilakukan dalam arah yang berlawanan:
tf.cumprod([a, b, c], reverse=True) # => [a * b * c, b * c, c]
Ini lebih efisien daripada menggunakan operasi tf.reverse terpisah.
Kwarg reverse dan exclusive juga dapat digabungkan:
tf.cumprod([a, b, c], exclusive=True, reverse=True) # => [b * c, c, 1]
Argumen:
- ruang lingkup: Objek Lingkup
- x:
Tensor . Harus berupa salah satu dari jenis berikut: float32 , float64 , int64 , int32 , uint8 , uint16 , int16 , int8 , complex64 , complex128 , qint8 , quint8 , qint32 , half . - axis:
Tensor bertipe int32 (default: 0). Harus berada dalam rentang [-rank(x), rank(x)) .
Atribut opsional (lihat Attrs ):
- eksklusif: Jika
True , lakukan cumprod eksklusif. - terbalik:
bool (default: False).
