compile 도중에 이런 문제가 발생합니다:

compiler log 를 열어봐도 도움 될 만한 내용이 없는거 같습니다:

어떤 operator 인지 찾고 싶은데 혹시 이 문제 해결은 어떻게 할까요?

`pytorch` 에서 제공하는 `torch.gather` 를 쓰려면 `torch.int64` 를 써야 하는데 npu 에서 `torch.int32`만 quantize 가능한걸로 기억해서 input 을 `torch.int32` 로 바꾸고 코드 안에서 `.long()` 을 써서 변환을 합니다. 혹시 이 문제 때문에 quantize 가 안되는걸까요?

안녕하세요, FuriosaAI 김종욱입니다.

혹시 int32로 변경하셨던 모델 파일을 jongwook.kim@furiosa.ai 로 전달해주실 수 있으실까요?
