Public Methods

| Interpreter.Options |
addDelegateFactory(DelegateFactory delegateFactory)
Adds a
DelegateFactory which will be invoked to apply its created Delegate
during interpreter creation. |
| Interpreter.Options |
setAllowBufferHandleOutput(boolean allow)
Advanced: Set if buffer handle output is allowed.
|
| Interpreter.Options |
setAllowFp16PrecisionForFp32(boolean allow)
This method is deprecated. Prefer using NnApiDelegate.Options#setAllowFp16(boolean
enable).
|
| Interpreter.Options |
setCancellable(boolean allow)
Advanced: Set if the interpreter is able to be cancelled.
|
| Interpreter.Options |
setNumThreads(int numThreads)
Sets the number of threads to be used for ops that support multi-threading.
|
| Interpreter.Options |
setRuntime(InterpreterApi.Options.TfLiteRuntime runtime)
Specify where to get the TF Lite runtime implementation from.
|
| Interpreter.Options |
setUseNNAPI(boolean useNNAPI)
Sets whether to use NN API (if available) for op execution.
|
| Interpreter.Options |
setUseXNNPACK(boolean useXNNPACK)
Enable or disable an optimized set of CPU kernels (provided by XNNPACK).

Public Methods
public Interpreter.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 Interpreter.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 Interpreter.Options setAllowBufferHandleOutput (boolean allow)
Advanced: Set if buffer handle output is allowed.
When a Delegate supports hardware acceleration, the interpreter will make the data
of output tensors available in the CPU-allocated tensor buffers by default. If the client can
consume the buffer handle directly (e.g. reading output from OpenGL texture), it can set this
flag to false, avoiding the copy of data to the CPU buffer. The delegate documentation should
indicate whether this is supported and how it can be used.
WARNING: This is an experimental interface that is subject to change.
Parameters
