인스턴스간 비교할때, 어느경우 is를 사용하고 어느경우 ==을 사용하는지 알고 싶습니다.   예를들어 아래와 같이 car2와 car3 내부 값이 동일한경우, car2 = Car('Bmw', {'color': 'Black', 'horsepower':'270', 'price':5000}) car3 = Car('Bmw', {'color': 'Black', 'horsepower':'270', 'price':5000}) 아래와 같이 == 이나 is로 비교했을 경우 모두 False가 나옵니다. Q. 인스턴스 끼리 비교할때 is 와 ==의 차이점이 무엇인가요? Q. 실제로 다른 인스턴스끼리 값이 같은 경우 True가 나오게 하는 방법은 없을까요? print(car2 == car3) print(car2 is car3)

제곧내입니다 저는 선생님처럼 잘린채로 선택이 안되요 ㅜㅜ

질문은 아니지만 간단히 해결할 수 있어 글 남기고 갑니다. 저의 경우 상품등록 페이지를 만들다 localhost:5000/${file} 이 cors 이슈가 있어 이미지 미리보기 기능이 구현이 안되었습니다. 아래와 같이 백엔드 서버에 cors를 해결하는 access control 부분을 추가 해보시길 바랍니다. app.get('*', (req, res) => {   res.header("Access-Control-Allow-Origin","*");   res.sendFile(path.join(__dirname, '/public/index.html')); });

이렇게 설정 하였지만, UserController requestMapping부분에서 user-service 부분을 빼고 요청 보내면 자꾸 404 에러가 뜹니다.. 그래서 다시 userController requestMapping에 user-service를 추가하니깐 404 에러 없이 데이터를 가져 오더라구요.. 그래서 지금 login 부분을 계속 실패하고 있는데, 뭐가 잘못되었는지 알 수 있을까요??   아 참고로 - RewritePath=/user-service/(?<segment>.*),/$\{segment} 이 모양과 - RewritePath=/user-service/(?<segment>.*), /$\{segment} 이 모양 둘다 해봤지만 결과는 계속 404 에러를 리턴합니다..

게임 매니저 스크립트에서 코루틴을 사용하고 싶어서 작성을 했는데 StartCoroutine 함수가 존재하지 않아서 게임 매니저에 MonoBehaviour를 상속받게 해봤습니다. 그런데 테스트를 해보니 다음과 같은 에러가 나네요. 아마도 인스펙터에 객체를 생성하지 않아서인듯 합니다. NullReferenceException UnityEngine.MonoBehaviour.StartCoroutine (System.Collections.IEnumerator routine) (at <9899854e5b05425ab27d31f737cde095>:0) 이 문제를 어떻게 해결하면 좋을까요? 코루틴용 스크립트를 따로 만드는 게 해결책일까요?

안녕하세요 기선님   아래와 같이 퀴즈를 풀었었는데 기선님은 Comparator를 정의(구현)하여 푸셨더라고요 저와 같이 Collections.reverseOrder() 를 사용한건 문제의 의도와 달랐던걸까요?   public static void main(String[] args) { ArrayList<Integer> arrayList = new ArrayList<>(); arrayList.add(10); arrayList.add(100); arrayList.sort(Collections.reverseOrder()); System.out.println(arrayList);}

  제가 pycharm으로 장고를 공부하는 중인데 DB를 만들려고 python manage.py migrate를 입력했습니다 위와 같이 출력값이 나와야지 정상인데       python 이렇게만 출력이 되고 더 이상 진행이 안 됩니다. 뭐가 문제인지 모르겠습니다.

[질문 내용]안녕하세요 영한님 JPA 를 공부하다가 LazyLoading 관련해서 의문점이 생겨 질문남깁니다. 연관관계에서의 LazyLoading 은 실제 entity를 가져오는것이 아닌 프록시객체의 target이 entity와 연결되어있는것으로 알고있습니다. 그래서 Team(1) <-> Member(n) 의 관계라고 가정했을때 Member 에서의 @ManyToOne 관계에서의 LazyLoading 으로 객체를 가져오게 되면 Team은 `Team$HibernateProxy$95RMKfgq@13875` 이런 형식으로 프록시 객체를 갖고있는것을 확인했습니다. 다만 Team에서 @OneToMany 관계의 Member를 LazyLoading 호출하게되면 List<Member> 의 형식이 PersistentBag 의 객체형식을 가지고있는것까지는 이해했는데 컬렉션 내의 객체는 제가 생각했던 `Member$HibernateProxy$95RMKfgq@13875` 와 같은 프록시 객체의 형태가 아닌 `Member@13867` 과 같은 실제 객체를 가지고 있는것으로 확인했습니다. 이와 관련해서 PersistenceCollection 이나 StatefulPersistenceContext 클래스의 관련된 문서를 찾아봤지만 답을 찾지못해 여쭤봅니다ㅠㅜ   추가로 entityManagerFactory getPersistenceUnitUtil().isLoaded 메소드를 이용해서 List 객체를 조회했을땐 false 로 확인했습니다. 다만 디버그모드로 봤을때는 ManyToOne 과 다르게 실제객체형태로 보이네요ㅠㅜ 디버그모드로 확인시 값을조회해야해서 의도치않게 추가쿼리가 발생되는것은 인지하고있지만 이 케이스는 이해가 되질 않네요 ㅎㅎ  

안녕하세요~ 혹시 강의 중 띄워주시는 ppt? 강의자료를 따로 다운받는 곳이 있을까요? 복습할때 활용하고 싶어서 질문 드립니다~

안녕하세요 아래 train 파라미터에서 rect가 있는데, 이는 letterbox와 상반된 개념인건가요? rect 시 mosaic 적용은 하지 않는데, 왜 letterbox로 입력을 넣는지도 궁금하네요 어떤 의미인지 궁금합니다 감사합니다 https://github.com/ultralytics/yolov5/blob/aa542ce6a65658ff931fee9bbab77c0145c152f0/train.py#L483

캐릭터 회전할 때 Yaw 회전과 마찬가지로 Pitch 회전(마우스 Y축)도 한번 적용시켜봤는데요 Yaw와 마찬가지로 AddControllerPitchInput 함수를 사용하였습니다. Yaw와는 다르게 회전이 안되었습니다..(로그도 찍어보고 구글링도 해봤는데.. ㅜ) 그래서 Use Controller Rotation Pitch가 false로 되어있는거 확인하고 생성자에서 bUseControllerRotationPitch를 true로 코딩해줬습니다. 이러니까 캐릭터 자체가 회전하더라구요.... 제가 원하는건 마우스 Y축을 따라서 카메라만 위아래로 회전하는 식으로 코딩해보고 싶은데 혹시 어느 함수를 사용해야할까요?

정밀도와 재현율 의미는 공식적으로는 알겠지만 실제 어떤 의미를 가지는지 이해하기 어렵습니다.   무엇에 대한 정밀함인지 어떤 현상이 재현이 잘 된다는 의미인지 잘 모르겠습니다.  

함수를 호출하면 값을 얻을수 있다고 하셨는데 별다른 설명없이 그냥 값을 구할수 있다고만 설명하셔서 무엇인지 궁금합니다.

안녕하세요. bean 등록 후 테스트 할 때 url 에 아래처럼 입력하는데요. /v1/request?itemId=hello 문득 생각해보니 OrderControllerInterfaceProxy 에는 @GetMapping 이 없는데 동작하는 것을 보니 인터페이스의 구현체에는 @GetMapping 을 명시하지 않아도 되는건가요?

추론하자면 아래와 같을 것 같은데요. FPRS : False Positive Rate S?  TPRS: True Positive Rate S?   FP, TP는 이전에 정수형으로 표현되었던것 같은데, 갑자기 확률로 나와서 어떤 의미인지 모르겠습니다. precision_recall_curve리턴 값처럼 정밀도, 재현율 일까요?

흔히 보던 빌더 패턴이나 롬복의 @Builder 애노테이션에서는 빌더 클래스를 inner static class로 만드는 방식을 사용했던 것 같은데 디렉터를 따로 두신 이유가 빌더의 구현체를 여러개를 사용한다면 클라이언트 측에서 디렉터에 어떤 빌더를 넣어 사용할 지 결정할 수 있도록 한거라고 이해하면 될까요?

코드를 변경하면 next 에서 자동적으로 hot loader 실행돼서 웹 사이트에서 변경이 되어야 하는데 웹 사이트에서 변경이 되지 않습니다.   그래서 현재 수동으로 새로고침으로 하고 있는데요 왜 안되는걸까요?

부모 컴포넌트<templete>   <router-view/></templete>    하위 컴포넌트 <templete>  <sub-content :props="props"/>  <router-view :props="props"/></templete>하위 컴포넌트에서 <sub-content/> 컴포넌트를 제외한 부분은라우팅에 따라 다르게 보여져야 할 것 같아서, 부모에도 <router-view/> 태그를 사용했고 하위 컴포넌트에도 <router-view/> 태그를 사용했는데요, 이렇게 구조를 짜니까 sub-content에는 props가 넘어가는데 하위 컴포넌트의 <router-view/>로 보내는props가 증발해버리더군요.  이럴 경우에는 아무리 <sub-content/>가 하위 페이지마다 반복해서 들어간다 할지라도 하위에서 <router-view>를 쓰지 않고,하위 컴포넌트에 일일이 <sub-content/>가 들어있는 컴포넌트를 따로 만들어야 되는건지... 궁금합니다. 아무래도 부모에 정의된 router-view 와하위에 정의된 router-view를 구분하지 못하고 props가 무시되는 거 아닐까 싶은데... 맞나요?

mongodb 연결은 잘 되있습니다...
