tflite_plugin_create_delegate()

TfLiteDelegate* tflite::tflite_plugin_create_delegate	(	char **	options_keys,
		char **	options_values,
		size_t	num_options,
		void(*)(const char *)	report_error
	)

This file defines two symbols that need to be exported to use the TFLite external delegate provider.

This is a plugin that can be used for fast integration of delegates into benchmark tests and other tools. It allows loading of a dynamic delegate library at runtime.

The external delegate also has Tensorflow Lite Python bindings. Therefore the dynamic external delegate can be directly used with Tensorflow Lite Python APIs.

See tensorflow/lite/delegates/external for details or visit the tensorflow guide here Implementation of the TfLite external delegate plugin

For details about what options_keys and option_values are supported please see: armnnDelegate::DelegateOptions::DelegateOptions(char const* const*, char const* const*,size_t,void (*)(const char*))
