tensoreflusso:: ops:: ResourceScatterNdAdd
#include <state_ops.h> Applica un'addizione sparsa a singoli valori o sezioni in una Variabile .
Riepilogo
ref è un Tensor di rango P e indices è un Tensor di rango Q .
indices devono essere tensori interi, contenenti indici in ref . Deve essere di forma [d_0, ..., d_{Q-2}, K] dove 0 < K <= P .
La dimensione più interna degli indices (con lunghezza K ) corrisponde agli indici in elementi (se K = P ) o fette (se K < P ) lungo la K -esima dimensione di ref .
updates sono Tensor di rango Q-1+PK con forma:
[d_0, ..., d_{Q-2}, ref.shape[K], ..., ref.shape[P-1]] Ad esempio, supponiamo di voler aggiungere 4 elementi sparsi a un tensore di rango 1 a 8 elementi. In Python, tale aggiunta sarebbe simile a questa:
ref = tf.Variable([1, 2, 3, 4, 5, 6, 7, 8], use_resource=True)
indices = tf.constant([[4], [3], [1], [7]])
updates = tf.constant([9, 10, 11, 12])
add = tf.scatter_nd_add(ref, indices, updates)
with tf.Session() as sess:
print sess.run(add)
L'aggiornamento risultante a ref sarebbe simile al seguente:
[1, 13, 3, 14, 14, 6, 7, 20]
Vedi tf.scatter_nd per maggiori dettagli su come apportare aggiornamenti alle sezioni.
Argomenti:
- scope: un oggetto Scope
- ref: un handle di risorsa. Deve provenire da un VarHandleOp.
- indici: A Tensore . Deve essere uno dei seguenti tipi: int32, int64. Un tensore di indici nel rif.
- aggiornamenti: Un Tensore . Deve essere dello stesso tipo del rif. Un tensore di valori da aggiungere al rif.
Attributi facoltativi (vedi Attrs ):
- use_locking: un valore bool opzionale. Il valore predefinito è Vero. Se True, l'assegnazione sarà protetta da un lucchetto; altrimenti il comportamento non è definito, ma può mostrare meno contesa.

It must be shape `[d_0, ..., d_{Q-2}, K]` where `0 \u003c K \u003c= P`.\n\nThe innermost dimension of `indices` (with length `K`) corresponds to indices into elements (if `K = P`) or slices (if `K \u003c P`) along the `K`th dimension of `ref`.\n\n`updates` is [Tensor](/versions/r1.15/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) of rank `Q-1+P-K` with shape:\n\n\n```transact-sql\n[d_0, ..., d_{Q-2}, ref.shape[K], ..., ref.shape[P-1]]\n```\n\n\u003cbr /\u003e\n\nFor example, say we want to add 4 scattered elements to a rank-1 tensor to 8 elements. In Python, that addition would look like this:\n\n\n```gdscript\nref = tf.Variable([1, 2, 3, 4, 5, 6, 7, 8], use_resource=True)\nindices = tf.constant([[4], [3], [1], [7]])\nupdates = tf.constant([9, 10, 11, 12])\nadd = tf.scatter_nd_add(ref, indices, updates)\nwith tf.Session() as sess:\n print sess.run(add)\n```\n\n\u003cbr /\u003e\n\nThe resulting update to ref would look like this: \n\n```text\n[1, 13, 3, 14, 14, 6, 7, 20]\n```\n\n\u003cbr /\u003e\n\nSee `tf.scatter_nd` for more details about how to make updates to slices.\n\nArguments:\n\n- scope: A [Scope](/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- ref: A resource handle. Must be from a VarHandleOp.\n- indices: A [Tensor](/versions/r1.15/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor). Must be one of the following types: int32, int64. A tensor of indices into ref.\n- updates: A [Tensor](/versions/r1.15/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor). Must have the same type as ref.
