Public Methods

publicGpuAccelerationConfig build()

Builds the GPU acceleration config.

public GpuAccelerationConfig.BuildersetCacheDirectory(Stringvalue)

Sets the directory to use for serialization. Whether serialization actually happens or not is dependent on backend used and validity of this directory.

NOTE: Users should ensure that this directory is private to the app to avoid data access issues.

public GpuAccelerationConfig.BuildersetEnableQuantizedInference(boolean value)

Enables inference on quantized models with the delegate. Defaults to true.

public GpuAccelerationConfig.BuildersetForceBackend(GpuAccelerationConfig.GpuBackend value)

Sets GPU backend to select. Default behaviour on Android is to try OpenCL and fall back to OpenGL if it's not available.

public GpuAccelerationConfig.BuildersetInferencePreference(GpuAccelerationConfig.GpuInferenceUsage value)

Sets GPU inference preference for initialization time vs. inference time.

public GpuAccelerationConfig.BuildersetInferencePriority1(GpuAccelerationConfig.GpuInferencePriority value)

Sets inference priority(1). Ordered priorities provide better control over desired semantics, where priority(n) is more important than priority(n+1). SeeGpuAccelerationConfig.GpuInferencePriorityfor more details.

public GpuAccelerationConfig.BuildersetInferencePriority2(GpuAccelerationConfig.GpuInferencePriority value)

Sets inference priority(2). Ordered priorities provide better control over desired semantics, where priority(n) is more important than priority(n+1). SeeGpuAccelerationConfig.GpuInferencePriorityfor more details.

public GpuAccelerationConfig.BuildersetInferencePriority3(GpuAccelerationConfig.GpuInferencePriority value)

Sets inference priority(3). Ordered priorities provide better control over desired semantics, where priority(n) is more important than priority(n+1). SeeGpuAccelerationConfig.GpuInferencePriorityfor more details.

public GpuAccelerationConfig.BuildersetModelToken(Stringvalue)

Sets the unique token string that acts as a 'namespace' for all serialization entries. Should be unique to a particular model (graph & constants). For an example of how to generate this from a TFLite model, see StrFingerprint().
