Public Methods
public InterpreterApi.Options addDelegate (Delegate delegate)
Adds a Delegate to be applied during interpreter creation.
Delegates added here are applied before any delegates created from a DelegateFactory that was added with addDelegateFactory(DelegateFactory).
Note that TF Lite in Google Play Services (see setRuntime(InterpreterApi.Options.TfLiteRuntime)) does not support
external (developer-provided) delegates, and adding a Delegate other than ERROR(/NnApiDelegate) here is not allowed when using TF Lite in Google Play Services.
Parameters
| delegate |
|---|
public InterpreterApi.Options addDelegateFactory (DelegateFactory delegateFactory)
Adds a DelegateFactory which will be invoked to apply its created Delegate
during interpreter creation.
Delegates from a delegated factory that was added here are applied after any delegates
added with addDelegate(Delegate).
Parameters
| delegateFactory |
|---|
public List<DelegateFactory> getDelegateFactories ()
Returns the list of delegate factories that have been registered via addDelegateFactory).
public List<Delegate> getDelegates ()
Returns the list of delegates intended to be applied during interpreter creation that have
been registered via addDelegate.
public int getNumThreads ()
Returns the number of threads to be used for ops that support multi-threading.
numThreads should be >= -1. Values of 0 (or 1) disable multithreading.
Default value is -1: the number of threads used will be implementation-defined and
platform-dependent.
public InterpreterApi.Options.TfLiteRuntime getRuntime ()
Return where to get the TF Lite runtime implementation from.
public boolean getUseNNAPI ()
Returns whether to use NN API (if available) for op execution. Default value is false (disabled).
public boolean getUseXNNPACK ()
public boolean isCancellable ()
Advanced: Returns whether the interpreter is able to be cancelled.
Interpreters may have an experimental API setCancelled(boolean).
If this interpreter is cancellable and such a method is invoked, a cancellation flag will be
set to true. The interpreter will check the flag between Op invocations, and if it's true, the interpreter will stop execution. The interpreter will remain a cancelled state
until explicitly "uncancelled" by setCancelled(false).
