- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 강의 내용을 질문할 경우 몇분 몇초의 내용에 대한 것인지 반드시 기재 부탁드립니다. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. 안녕하세요. 규제 부분 코드 실습 중 규제 클래스에 관해서 cross_val_score적용 시 NaN값이 반환되는 것이 확인되어 질문드립니다. 싸이킷런 버전의 경우 1.0.2버전인데 구글링을 했을 때는, 데이터 내에 NaN값이 있어서 그럴 것이라는데 제가 확인해봤을 때는 NaN값이 없었습니다. 혹시 버전과 관련된 문제일까요...? 동일 코드에 Ridge클래스대신 LinearRegression클래스로 대체시 정상적으로 코드가 동작하는 것을 확인하여 우선 Ridge클래스에 대한 문제로 간주하고 있습니다...ㅠ
OS: macOS python 3.10 버전을 사용하고 있고, sqlalchemy 2.0.19, pymysql 1.1.0 등등 최신 패키지 사용중입니다. from sqlalchemy import create_engine from sqlalchemy.orm import sessionmaker DATABASE_URL = "mysql+pymysql://root:todos@127.0.0.1/todos" engine = create_engine(DATABASE_URL, echo=True) SessionFactory = sessionmaker(autocommit=False, autoflush=False, bind=engine) connection.py 는 위와 같이 동일하게 작성했고, session.scalar(select(1)); 실행시 아래와 같은 오류가 발생하여 더 이상 진행을 할 수가 없습니다.

이전에 혼자 ddd, 헥사고날 아키텍처를 공부하면서 느꼈던게 객체지향적인 코드 + 테스트하기 용이한 코드를 작성하기 위해서는 결국 domain layer와 persistence layer의 분리가 필수적인데 jpa entity와 domain entity를 완전히 분리했을 때 JPA가 mybatis나 jdbc template를 사용하는 것과 비교해 가지는 강점이 있는지 잘 모르겠습니다.. 그나마 jpa entity와 domain entity를 분리하지 않는다면 어떻게든 온몸 비틀기로 그나마 테스트하기 용이하고 객체지향스러운 코드를 작성해볼 수는 있지만 결국 복잡한 로직에서는 쿼리 때문에 문제가 생기고 ㅜ 지식 공유자님께서는 이 문제에 대해 어떻게 생각하시나요?
Collection.Map의 Good 케이스를 알 수 있을까요? 맵을 사용할 때 맵 안에 맵이 있고 이런 형태를 사용하지 않는게 좋은건지 아니면 따로 dto로 변환해서 사용해야하는건지 구분이 안 가서 질문 드립니다 ! 지정된 scope를 넘나들지 않는다는 것도 이해가 가지 않습니다 ㅠㅠ 조금만 더 쉽게 설명 붙여주시면 감사드리겠습니다!
강의에서는 아래와 같이 select 쿼리를 이용해 업데이트 된 회원을 조회후 response로 전달해 주었는데 @PutMapping("/api/v2/members/{id}") public UpdateMemberResponse updateMemberV2(@PathVariable("id") Long id, @RequestBody @Valid UpdateMemberRequest request) { memberService.update(id,request.getName()); Member findMember = memberService.findOne(id); return new UpdateMemberResponse(findMember.getId(), findMember.getName()); } 아래와 같이 하지 않은 이유가 있을까요?? @PutMapping("/api/v2/members/{id}") public UpdateMemberResponse updateMemberV2(@PathVariable("id") Long id, @RequestBody @Valid UpdateMemberRequest request) { memberService.update(id, request.getName()); return new UpdateMemberResponse(id, request.getName()); }
제목처럼 Sequenital을 import해서 쓰는 것과 keras.Sequential을 쓰는 것의 차이가 있나요? models의 차이가 있는지 궁금합니다. 실행했을 땐 똑같긴한데.. 굳이 왜 다른지 궁금합니다. Dense(1, input_shape = (2, ), ....) 에서 왜 2가 앞에 쓰이는 건가요?? 앞은 보통 행인데...ㅠㅠ keras가 행은 몇개인지 몰라도 되는데 피쳐는 몇개인지 알아야 하는건가요?
클래스의 상속과 관련된 다형성은 부모객체로 인스턴스를 생성하여 부모클래스의 메소드와 자식클래스 메소드 2가지를 업/다운캐스팅하여 자유롭게 호출할 수 있지만, 단일상속이라는 한계 때문에 다른 부모클래스의 메소드는 호출할 수가 없잖아요? 그래서 인터페이스가 존재하는 이유구요. 마찬가지로, 인스턴스를 생성할 때 다형성을 활용하여 인터페이스 객체(부모 객체)로 생성할 수는 있지만, 이것은 ISP(Interface Segregation Principle)원칙에 따라 detect(), report() 2개의 메소드를 호출하려면 Detectable, Reportable 객체 2개를 생성해야 하기 때문에 메모리가 효율적으로 관리되지 못하는거구요. 따라서 구상클래스인 FactoryCam에서 인터페이스 변수를 직접 생성하고 setter함수로 필요한 인터페이스 변수를 주입한 다음(Dependency Injection) , 주입당한 객체는 인터페이스에 의존하기 때문에(Reportable, Detectable) 동시에 기능이 다른 2가지 메소드를 호출할 수 있는거구요.(Dependency Inversion Principle) ... 과정을 이해하였지만 말로 풀어내니까 굉장히 장황하군요 사실 이 부분은 인터페이스 문법이라기보다는 디자인 패턴과 관련이 있지 않나싶습니다.
방향 그래프 무방향 그래프에 따라서 자료구조에 자료를 저장하는 방법이 다르다고 하셨습니다. 그런데 지금 이 문제에서는 방향그래프 아닌가요?? 간선,엣지들을 보면 모두 방향이 있는 거 같은데, 왜 무방향그래프를 저장할 때처럼 arraylist에 값을 저장하는지 모르겠습니다.

안녕하세요 교수님! ModelCheckpoint에서 ModelCheckpoint('best_model.h5', save_weights_only=True, monitor='val_loss', save_best_only=True, mode='min') save_weights_only = True로 했을 때 아래와 같은 load_model 에러가 나더라구요.. 그래서 구글링을 해봤는데 저렇게 설정할 경우에 모델 아키텍처가 저장이 안되어서 load_model을 할 수 없다고 json 파일로 모델을 따로 저장하고 나중에 json 모델을 다시 불러오는 방법을 사용하라고 나왔습니다. 강의 중에도 언급해주셨지만 save_weights_only = True로 했을 때의 이점이 있을까요..? False로 했을 때 교수님께서 모델을 불러올 때 충돌..? 비슷한 것이 난다고 하셨는데 좀 더 세부적인 내용을 알고 싶습니다..! 만약에 True로 설정했다면 매번 json으로 모델을 저장하는 과정을 거쳐야 하는 것인지 궁금합니다! model.save () 함수도 있던데 이거는 modelcheckpoint와 달리 학습 중에 저장은 안되는 것 같아서요.. 항상 감사합니다 교수님!!

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 강의 내용을 질문할 경우 몇분 몇초의 내용에 대한 것인지 반드시 기재 부탁드립니다. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. 강의에서 conv2d연산을 진행한 후에 softmax연산을 해주기 위해 3차원 데이터를 flatten시켜줬는데 flatten시켜준 후에 바로 softmax함수를 적용시키면 어떤 이유로 정보가 손실되는 이유에 대해서 궁금합니다. dense를 하나 추가하고 softmax를 적용하는 것과 dense없이 flatten후 softmax를 적용하는 것의 차이점에 대해서 궁금증이 생긴 것 같습니다!
안녕하세요! 강사님 강의를 끝까지 다 수강하였습니다. 너무 도움이 많이 되었습니다. 감사합니다. 부동산 매물 강의에 대한 공지를 보고 메일로 문의 드렸는데 아직 피드백이 오지 않아 이렇게 질문글로 문의를 드리게 되었습니다! 메일 문의 한 번만 확인 부탁드립니다. 감사합니다!
Java 에서 Final 만 사용할 수 있는게 외부 변수가 메모리에서 해제 되었을 경우, 가비지를 참조할 수 있는 것을 방지하기 위해서로 알고 있는데 코틀린은 이게 가능한게 아예 메모리를 통째로 떠와서 그런걸까요? ㅎㅎ 강의 영상에서 포획한다 라고 표현하신게 그런 의미 같아요!
