강의를 듣고 직접 RNN을 구현하는 것을 시도했습니다.   하나의 물체를 다른 위치에서 촬영하고 각 사진마다 물체 좌표값(x,y)을 추출했습니다. 얻은 좌표값을 이용해서 실제 3D 좌표(x,y,z)로 예측하는 것을 만들려고 합니다.   제가 생각한 모델구성은 아래와 같습니다. 하지만, 모델을 구현해보니 좌표값이 1개만 출력되고 출력된 값이 무엇을 예측하고 나왔는지 모르겠습니다.   어디를 수정해야 x,y,z값이  출력되나요?   아래는 사용된 소스 및 데이터 일부입니다. import numpy as np import pandas as pd import torch from sklearn.model_selection import train_test_split import torch.nn as nn import

이렇게 오류가 뜨는데 실행은 됩니다 이건 어떠한 경우인가요?

코드를 동일하게 한 것 같은데, 드래그 기능 작동이 안됩니다. 이유가 궁금합니다. import React from "react"; import { DragDropContext, Draggable, Droppable } from "react-beautiful-dnd"; export default function List({ todoData, setTodoData }) { const handleClick = (id) => { let newTodoData = todoData.filter((data) => data.id !== id); console.log("newTodoData", newTodoData); //this.setState({ todoData: newTodoData }); setTodoData(newTodoData); }; const handleCompleteChange = (id) => { let newTodoData = todoData.map((data) => { if (data.id === id) { data.complited = !data.complited; } return data; }); //this.setState({ todoData: newTodoData }); setTodoData(newTodoData); }; return ( <div> <DragDropContext> <Droppable droppableId="todo"> {(provided) => ( <div {...provided.droppableProps} ref={provided.innerRef}> {todoData.map((data, index) => ( <Draggable key={data.id} draggableId={data.id.toString()} index={index} > {(provided, snapshot) => ( <div key={data.id} {...provided.draggableProps} ref={provided.innerRef} {...provided.dragHandleProps} className={`${ snapshot.isDragging ?

강사님 안녕하세요.   지난 번 TDD 오류가 났고 문제 해결했는데   그 이후로 계속해서 오류가 나지 않고 ok만 뜨고 있네요.   이럴 땐 어떻게 문제를 해결하면 좋을까요? 깃허브에 커밋해주신 코드를 살펴보면서 수정하면 좋을까요..?   접근 방법을 잘 몰라서 문의 드립니다.

안녕하세요 학습중에 질문드립니다. 다름이 아니라 궁금증이 있습니다. localstorage에 있는key값을 받아와 List에 뿌려주는 방식인데 TodoList.vue내에서 키값 중복에 대한 유효성검사를 따로 하지 않았는데 중복값이 들어가지 않습니다. localStorage내부에서 자체적으로 중복값 유효성검사를 하는건가요? 알고싶습니다.

df = pd.read.csv('/kaggle/input/london-bike-sharing-dataset/london_merged.csv',arse_dates * ['timestamp'])df.head()   이거 맞나요?

Category 컴포넌트가 아래 그림과  같이 아래로 생성됩니다. 의미적으로는 div 태그가 추가되는 것이어서 아래 출력이 맞는 것 같긴 한대요. 강사님 수업에서는 옆으로 Category가 붙더라구요. (아래 코드는 Github 강사님 수업 소스에서 API로 읽어와 상태변경하는 부분만 변경하였음)      

앞서 @Component나 @Autowired를 배우기 이전에는 코드를 아래처럼 작성했었습니다. public class MemberServiceImpl implements MemberService{ private final MemberRepository memberRepository; public MemberServiceImpl(MemberRepository memberRepository) { this.memberRepository = memberRepository; } @Component, @Autowired와 같은 Annotation을 사용하지는 않았지만 AppConfig를 통해 직접 스프링빈으로 등록해두었다고 이해하고 있는데,   그렇다면 저 생성자 주입이 이루어지는 부분은 스프링에 의한 '의존관계 자동주입'이 맞을까요?   @Autowired는 생성자가 하나일 때 생략이 가능하다고 했으니, 위의 예제는 스프링빈을 직접 등록한 뒤 @Autowired가 생략된 형태로 생성자 주입을 했다고 볼 수 있는건지요?   추가로, @Autowired를 사용하기 위해서는 DI의 대상이 되는 memberService, memberRepository 모두 스프링빈이어야 하는지, 주입되는 memberRepository만 스프링빈이어도 가능한 것인지 궁금합니다.

안녕하세요 김영한 강사님,   OSIV를 false로 하면 트랜잭션 라이프사이클이랑 영속성 라이프 사이클이이 같이 끝맺음을 가지는거로 이해했습니다.   그렇다면 트랜잭션 안에서 엔티티를 save메소드로 저장 한다면 트랜잭션이 끝나고난뒤에 DB에 저장하기위해 인서트문이 날라가는게 아닌가요?   트랜잭션 메소드를 끝낸뒤 로그로 엔티티는 찍히는데 디비에는 저장이안되어있어서   findBy등으로 찾아오지못해 제가 정확히 이해를 못하는것인지, 아니면 잘못 사용하고있는것인지 궁금합니다.   트랜잭션안에서 save를 한뒤 정상적으로 끝난뒤에도 디비에는 존재하지 않는 이유는 무엇인가요?  

step1의 batchstatus가 왜 complete가 아닌 abandoned인지 잘 모르겠습니다. 

안녕하세요 🙋‍♂️한 입 크기로 잘라먹는 리액트 강사 이정환 winterlood입니다!물론 질문은 수강생 여러분들 편하게 해 주시면 되지만!아래의 몇 가지 규칙만 지켜주시면 더 빠르고 정확한 답변을 드릴 수 있습니다!- 개인적인 고민 상담도 받아드립니다 :)- 강의의 몇 분 몇 초 관련 질문인지 알려주세요!- 서로 예의를 지키며 존중하는 문화를 만들어가요. - 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.   안녕하세요! 최종 프로젝트 edit 페이지 구현하다가 감정 이미지가 제대로 나타나지 않아서 질문드립니다! 강사님처럼 DiaryEditor 컴포넌트를 만들어서 new 페이지랑 edit 페이지에 공통으로 사용하였는데, new 페이지에서는 잘 나오는 이미지가 edit 페이지에서는 제대로 안 나오더라구요. 그리고 diary 컴포넌트에서도 이미지가 나오지 않습니다.. emotionList의 img 경로에 문제가 있는 걸까요? 저와 비슷한 질문을 남기신 분께 process.env 를 수정하셔야 할 거 같다고 강사님이 답변을 남기셨던던데, 제가 그것만 보고는 어떻게 수정을 해야할지 잘 감이 오지 않아 코드 샌드박스로 코드 남깁니다!   codesandbox-url   감사합니다!

강의대로 똑같이 따라했는데, 테이블이 사진처럼 item, orderitem 두가지 밖에 생기지 않습니다. 혹시 제가 어디 잘못 작성한 것이 있는지 알 수 있을까요?

안녕하세요 저같은 초보자분들이 계실까봐 여기 적어놓습니다ㅎㅎ 강의에서 나온 WebSecurityConfigurerAdapter가 현재 2022년에는 deprecated되었네요...ㅜ 그래서 저도 약간 해매었는데요.. 처음 공부할 때는 그래도 데이터쌓는개념이고, 각자의 인내심을 해당 프레임워크에 익숙하게 하는데도 바쁠 것같아 코드 올려 놓습니다ㅎㅎ 참고하세요!   @Configuration @EnableWebSecurity //스프링 시큐리티 필터가 스프링 필터체인에 등록 (스프링 필터 사용해봣쥬?) public class SecurityConfig{ @Bean public SecurityFilterChain filterChain(HttpSecurity http) throws Exception { http.csrf().disable(); http.authorizeRequests() .antMatchers("/user/**").authenticated() .antMatchers("/manager/**").access("hasAnyRole('ROLE_MANAGER','ROLE_ADMIN')") .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')") .anyRequest().permitAll(); return http.build(); } /* 기존: WebSecurityConfigurerAdapter를 상속하고 configure매소드를 오버라이딩하여 설정하는 방법 => 현재: SecurityFilterChain을 리턴하는 메소드를 빈에 등록하는 방식(컴포넌트 방식으로 컨테이너가 관리) //https://spring.io/blog/2022/02/21/spring-security-without-the-websecurityconfigureradapter @Override protected void configure(HttpSecurity http) throws Exception{ http.csrf().disable(); http.authorizeRequests() .antMatchers("/user/**").authenticated() .antMatchers("/manager/**").access("hasRole('ROLE_ADMIN') or hasRole('ROLE_MANAGER')") .antMatchers("/admin").access("\"hasRole('ROLE_ADMIN')") .anyRequest().permitAll(); } */ }

@Component public class CustomBCryptPasswordEncoder extends BCryptPasswordEncoder { } 위 처럼 따로 BcryptPasswordEncoder를 만들어주고 컨테이너에  등록합니다! //해당 메서드의 리턴되는 오브젝트를 IoC로 등록해준다. /* @Bean() public BCryptPasswordEncoder encoder(){ return new BCryptPasswordEncoder(); } */ 그리고 위의 코드(SecurityConfig)를 저처럼 주석으로 처리해주세요! 순환 참조가 나는 이유: 1. SpringContainer에서 처음 빈으로 등록하기 위해 객체를 생성 하여 줍니다(싱클톤) 2. 그래서 SecurityConfig 객체를 생성하던 중  PrincipalOauth2UserService객체를 의존하고있네요?그래서 PrincipalOauth2UserService를 만들어 주는데.. 3. 어라? PrincipalOauth2UserService에서도 SecurityConfig에서빈으로 등록한 BCryptPasswordEncoder를 참조하고있네?? 4. 오잉? 스프링:참조가 순환되넹?아아아아아악! => 오류 즉, SecurityConfig -> PrincipalOauth2UserService, 다시 PrincipalOauth2UserService->SecurityConfig   그래서 저는 SecuritiConfig -> PrincipalOauth2UserService-> CustomBCryptPasswordEncoder 로 구조를 변경하였습니다.

edit에서 작성되어있는 방식이   useEffect 에서 postNum을 가지고 /api/post/detail 에서 글을 찾아와서 setPostInfo 를 넣어주고 title과 content를 set해주는건데   DB를 한번 읽어서 가져오면 비효율적이지않나요?   detail 페이지에서 넘어올때 값을 넘겨주는 방식은 어떤가요? 그리고 setTitle과 setContent를 detail에서 글정보를 들고올때 한번에 설정해주면 useEffect를 한번이라도 줄일수 있을까요?  

안녕하세요, 04:22에서 밑줄 쳐 주신 구문과 똑같이 작성하였는데아래와 같은 에러가 발생합니다.해당 구문에 대해서 첨언을 해 주실 수 있을까요?
