tensorflow brace-enclosed initializer list

그냥 손에 익숙한(!) v2.4.1을 써서 그런가(구버전 api라서?)

해당 함수가 존재하지 않는다고 에러가 발생하고 빌드에 실패한다.

검색해보니 c++x00

그나저나 api 문서가 업데이트 늦을수도 있지만

아래의 원형밖에 없는데 std::unique_ptr이 std::initializer_list일 리는 없을테고. 도대체 어떤 함수를 써야 하는걸까?

TfLiteStatus ModifyGraphWithDelegate(   TfLiteDelegate *delegate ) TfLiteStatus ModifyGraphWithDelegate(   std::unique_ptr< Delegate, Deleter > delegate ) TfLiteStatus ModifyGraphWithDelegate(   std::unique_ptr< TfLiteDelegate > delegate )=delete
