Mengembalikan jumlah elemen dari daftar tensor.
`tf.accumulate_n_v2` melakukan operasi yang sama seperti tf.add_n , tetapi tidak menunggu semua inputnya siap sebelum mulai menjumlahkan. Hal ini dapat menghemat memori jika masukan siap pada waktu yang berbeda, karena penyimpanan sementara minimum sebanding dengan ukuran keluaran, bukan ukuran masukan.
Berbeda dengan `accumulate_n` yang asli, `accumulate_n_v2` dapat dibedakan.
Mengembalikan `Tensor` dengan bentuk dan tipe yang sama dengan elemen `input`.

Mengembalikan pegangan simbolis tensor.
Masukan ke operasi TensorFlow adalah keluaran dari operasi TensorFlow lainnya. Metode ini digunakan untuk mendapatkan pegangan simbolis yang mewakili perhitungan input.
Metode pabrik untuk membuat kelas yang membungkus operasi AccumulateN baru.
