안녕하세요 강의 수강중 python을 설치하여 git bash에서 $ pip를 입력하는 과정에서 bash: pip: command not found가 출력될 경우에는 어떤 조치를 취할 수 있을까요? 완전 처음이라 문의 남깁니다.

안녕하세요. 9장강의를 듣고 추가 과제를 시도해보던 중 궁금증이 생겨 질문드립니다. 스스로 해보기 -> 팔로잉 끊기 에서 destory와 라우터를 사용하라고 안내해주셨는데 user자체를 삭제하는 것이 아닌 중간테이블(follow)에서 해당 로우만 삭제하는 방법이 따로 있나요? if (user) { const a = await user.destroy({ where: { Followings: { followerId: req.params.id } }, }); 위와 같이 방법을 여러가지로 시도해보았지만 계속해서 유저 삭제(탈퇴)가 되는 상황이라 도움주시면 감사하겠습니다..!

스프링부트 시큐리티 & JWT 강의
안녕하세요. 강사님! 수업 정말 잘 들었습니다! 비전공자로써 3개월째인데 JWT 강의 중에 정말 이해가 잘 되었습니다!!! 진심으로 감사합니다~~ 다름이 아니라 더 나아가서, JWT와 Oauth2를 붙이려고 하는데 JWT 강의 초반에 기존의 Oauth2 방식을 사용하지 않고 다른 방식을 써야 된다고 하셔서 질문합니다. 어떤 부분이 달라져야할지 전혀 감이 안 오는데, 제가 조금 참고할만한 자료가 있을까요? 혹시 JWT+Oauth를 붙이려고 할 때 코드가 많이 변경될까요? (혹시 강의 제작하실 생각 없으신가요...ㅎㅎ)

스프링부트 시큐리티 & JWT 강의
PrincipalDetails 시큐리티가 /login을 낚아채서 로그인을 진행시킨다. PrincipalDetailsService 시큐리티 설정에서 loginProcessingUrl("/login") 처리 이게 view를 리턴하는 방식에서는 formLogin을 처리해줘서 이렇게 여기서 작성하면 controller에서 기능을 구현하지 않아도 login을 시큐리티가 알아서 해주는 걸로 알고 있는데요. 그러면 REST API 방식일때는 SecurityConfig에 formLogin.disable()로 처리하는 걸로 알고 있는데 그러면 PrincipalDetails, PrincipalDetailsService은 REST 방식에서는 작성하지 않는건가요? 근데 그러면 의문이 저 2개의 클래스를 생성하지 않으면 @Data public class PrincipalDetails implements UserDetails, OAuth2User { private User user; private Map<String, Object> attributes; // 일반 로그인 public PrincipalDetails(User user) { this.user = user; } // Oauth 로그인 public PrincipalDetails(User user, Map<String, Object> attributes) { this.user = user; this.attributes = attributes; } // 해당 User의 권한을 리턴하는 곳 @Override public Collection<? extends GrantedAuthority> getAuthorities() { Collection<GrantedAuthority> collection = new ArrayList<>(); collection.add(new GrantedAuthority() { @Override public String getAuthority() { return user.getRole(); } }); return collection; } // 사용자의 패스워드를 반환 @Override public String getPassword() { return user.getPassword(); } @Override public String getUsername() { return user.getEmail(); } // 계정 만료 여부 반환 @Override public boolean isAccountNonExpired() { // 만료되었는지 확인하는 로직 // true = 만료되지 않음 return true; } // 계정 잠금 여부 반환 @Override public boolean isAccountNonLocked() { // true = 잠금되지 않음 return true; } // 패스워드의 만료 여부 반환 @Override public boolean isCredentialsNonExpired() { // 패스워드가 만료되었는지 확인하는 로직 // true = 만료되지 않음 return true; } // 계정 사용 가능 여부 반환 @Override public boolean isEnabled() { // 계정이 사용 가능한지 확인하는 로직 // true = 사용 가능 return true; } @Override public Map<String, Object> getAttributes() { return attributes; } @Override public String getName() { return null; } } 여기서 UserDtails, OAuth2User을 상속받아서 Override하는 부분은 어떻게 구현하나요?

authorities가 들어갔다고 나옵니다 하지만 getUserName을 통해 확인해보면 안들어간게 맞습니다... 회원가입후 반환하는 값이 authorities안에 authority가 한겹 더있는 상태라 권한정보를 인식을 못하는 것 아닌가라는 생각을 했는데 admin 같은경우에는 잘 됩니다. 며칠째 붙잡고있는데 해결을 못하고 물어볼만한 곳이 없어 여기에 남겨봅니다...

[퇴근후딴짓] 빅데이터 분석기사 실기 (작업형1,2,3)
안녕하세요 선생님 현재 모델링 및 평가(회귀)부분을 학습하고 있습니다. 코드를 따라가면서 실습을 진행하고 있는데, rmse 값이 선생님과 달라 질문 드립니다. 제가 알기로는 모델링을 하는 과정에서 예측한 값이 달라질 수 있고, 이에 따라 평가지표인 rmse 값이 다를 수 있다...라고 알고 있습니다. 그런데 값의 차이 뿐만이 아니라 baseline과 scaler 적용 결과가 좋은지 나쁜지가 달라 질문드립니다. 예를 들어, 선생님께서 하셨을때는 RandomForestRegressor의 baseline이 rmse값이 가장 좋았고(작았고), scaler를 적용했을 때 rmse가 커져서 scaler 적용은 하지 않는게 좋다~라는 내용의 실습이었는데 제가 했을 때는 baseline의 rmse보다 scaler를 적용했을 때의 rmse가 작아 scaler를 적용하는 것이 좋다..는 결론이 나옵니다. 질문을 정리하자면, 모델링을 하는 과정에서 선생님과 제가 실습한 예측값과 rmse가 다른게 맞는지 다른게 맞다 해도 scaler 적용여부 등을 바꿀 수 있을 정도로 예측값과 rmse가 달라질 수 있는지 (추가질문)달라지더라도 선생님 실습값 : 4728.xx 제 실습값 6025.174022213681 이정도로 달라질 수 있는지... (추가질문) 모델링 및 평가(회귀) 24:56에서 수험자는 알 수 없는 영역>y_test로 rmse로 구하시고 결과값이 17909.xx로 나왔는데 여기에서도 charges에 로그변환 한 이후기 떄문에 원래는 np.exp(pred)로 rmse를 구했어야 하는지 일 것 같습니다. 감사합니다.

컨트롤러와 서비스에 NotFoundException을 둘다 작성하셨는데 혹시 필요없는 로직이 아닌지 생각됩니다. 컨트롤러에서 데이터를 받았는데 서비스로 데이터가 안넘어 갈일은 없다고 생각되서요 꼭 필요한 코드인지 의문입니다.
