string log_id = "Foo";
auto logging_manager = std::make_unique<LoggingManager>
(std::unique_ptr<ISink>{new CLogSink{}},
static_cast<Severity>(lm_info.default_warning_level),
false,
LoggingManager::InstanceType::Default,
&log_id)
Environment::Create(std::move(logging_manager), env)
InferenceSession session_object{so,env};
session_object.RegisterExecutionProvider(std::make_unique<::onnxruntime::NnapiExecutionProvider>());
status = session_object.Load(model_file_name);
