tensoreflusso:: ops:: Variabile temporanea
#include <state_ops.h>
Restituisce un tensore che può essere modificato, ma persiste solo all'interno di un singolo passaggio.
Riepilogo
Questa è un'operazione sperimentale solo per uso interno ed è possibile utilizzarla in modi non sicuri. NON UTILIZZARE a meno che non si comprendano appieno i rischi.
È responsabilità del chiamante assicurarsi che "ref" venga eventualmente passato a un'operazione " DestroyTemporaryVariable " corrispondente dopo che tutti gli altri utilizzi sono stati completati.
Emette un riferimento allo stato del tensore in modo che possa essere letto o modificato.
Ad esempio, var = state_ops._temporary_variable([1, 2],types.float_) var_name = var.op.name var = state_ops.assign(var, [[4.0, 5.0]]) var = state_ops.assign_add(var, [[ 6.0, 7.0]]) final = state_ops._destroy_temporary_variable(var, var_name=var_name)
Argomenti:
- scope: un oggetto Scope
- forma: la forma del tensore variabile.
- dtype: il tipo di elementi nel tensore variabile.
Attributi facoltativi (vedi Attrs
):
- var_name: sovrascrive il nome utilizzato per la risorsa variabile temporanea. Il valore predefinito è il nome dell'operazione ' TemporaryVariable ' (che è garantita univoca).
Resi:
-
Output
: un riferimento alla variabile tensore.
