코드에'raw_input'이 없습니다 ... 아마도'...'에서 사라 졌나요? – Billy

재생할 수 없습니다. '...'를 제거하고'proj1' 객체를 생성 한 후에,이 코드는 (적어도 파이썬 2에서는) 잘 동작했습니다. 문제를 나타내는 실행 파일을 게시하십시오. – tdelaney

raw_input은 클래스로 작성되었으며 클래스 코드에는 표시되지 않습니다. raw_input의 목적은 무엇입니까? – Tensor

저는 dill입니다. 다른 설정 (예 : byref)은 dump에 포함 된 개체 유형을 수정하는 데 사용됩니다. pickle 및 따라서 dill은 재귀 개체 직렬화를 사용합니다. 즉, 개체가 다른 개체를 참조 할 때 직렬화 설정에 따라 직렬화 할 수도 있고 그렇지 않을 수도 있습니다. pickle은 일반적으로 함수 및 클래스 을 (byref=True)으로 직렬화합니다. 즉, 가져 오기 및 이름에 대해서만 serialize됩니다. dill에는 byref=False (참조 대신 함수 및 클래스 개체를 직렬화 함)과 같은 여러 설정이 있습니다. 도 있습니다. recurse=False은 전역 참조를 직렬화하는 방법을 다루는 반면 recurse=True은 전역에있는 참조 된 항목과 해당 항목이 참조하는 항목 등을 직렬화합니다.

간단히 말해서, 직렬화하는 모든 것이 어떤 글로벌 참조를 가지며, 어떤 것이 피클 할 수없는 dill에 도달 할 때까지 재귀 직렬화를 트리거합니다.

다음은 시도 할 수있는 몇 가지 있습니다 : 별도의 파일로 파일에서

별도의 객체 -이 참조로 산세에 더 의존 할 수 있습니다.
다른 개체 (예 : recurse=True)를 사용하여 dill 개체를 대상 개체와 일련 화하려고 시도하는 개체를 변경합니다. dill.settings을 사용하여 설정을 전역 적으로 설정할 수 있습니다.
클래스에 직렬화 도우미 메서드를 추가하면 클래스를 serialize하는 방법을 pickle에게 알립니다.
직렬화 문제를 피하기 위해 클래스의 리팩토링 (어떻게 든 내용을 볼 수 없기 때문에).

오류를 보여주는 작동 예제를 게시하지 않았으므로 더 자세히 대답하기가 어렵습니다.

오류 메시지 : "PicklingError : <내장 함수 raw_input>을 pickle 할 수 없습니다 : __builtin __. raw_input과 같은 개체가 아닙니다." __builtin__ 메서드가 내 클래스 생성 과정에서 변경되었음을 의미합니다. 어떻게 내장 클래스의 정의를 변경할 수 있습니까? (이상하게 보입니다). – Tensor

@Tensor : 사실이 아닙니다. 그 오류를 보는 가장 일반적인 이유는 객체 ('builtin.raw_input')은 실제로 네임 스페이스에서 정의되지 않았으며 어떤 방법으로 거기에 별칭이 지정되었습니다. 객체 앨리어싱이 많이 이루어지기 때문에 이것은 매우 일반적인 산세 오류입니다. 이것이 파이썬 3이'qualname' 속성을 도입 한 이유 중 하나입니다. 불행히도'dill'은 아직 활용하지 못했습니다. –

그럼 어떻게이 오류를 해결할 수 있습니까? – Tensor
