전에 알려주셨던 대로 해서 초기 실행 과정은 성공했습니다! 그런데 여기서 깃에 있는 로그인 관련 앱 코드 올려주신 것을 통해 구동을 해보려고 하는데 첫 번째 사진과 같이 버젼 오류가 떠서 이것을 해결하려고 아래 사진과 같은 시도를 해보았는데 결과가 저런 에러가 떴어서 어떻게 해야할 지 모르겠습니다. 구글링 해보면서 찾아보고 있지만 마땅히 해결이 되지 않아서 도움 요청합니다! 

=================현업자인지라 업무때문에 답변이 늦을 수 있습니다. (길어도 만 3일 안에는 꼭 답변드리려고 노력중입니다 ㅠㅠ)강의에서 다룬 내용들의 질문들을 부탁드립니다!! (설치과정, 강의내용을 듣고 이해가 안되었던 부분들, 강의의 오류 등등)이런 질문은 부담스러워요.. (답변거부해도 양해 부탁드려요)개인 과제, 강의에서 다루지 않은 내용들의 궁금증 해소, 영상과 다른 접근방법 후 디버깅 요청, 고민 상담 등..글쓰기 에티튜드를 지켜주세요 (저 포함, 다른 수강생 분들이 함께보는 공간입니다.)서로 예의를 지키며 존중하는 문화를 만들어가요.질문글을 보고 내용을 이해할 수 있도록 남겨주시면 답변에 큰 도움이 될 것 같아요. (상세히 작성하면 더 좋아요! )먼저 유사한 질문이 있었는지 검색해보세요.잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.==================안녕하세요 너무나 강의를 잘 듣고있고 도움을 많이 받고있습니다. 제가 강의이후에 강의 내용에 대해서 복습을 하려고 할때 강의자료가PPT나 PDF와 같은 자료가 없어서... 따로 적으면서 공부하고 있는데 이부분을 혹시 제공 받을 방법이 있을까하여 문의드립니다! (부담드리는건 아닙니다!)

만약 이 네이버 로그인까지 진행하고 로그인을 완료하면 index 페이지로 이동을 하는데,jwt토큰을 생성하려면 어떻게 해야 되나요?Service 에서 생성하고 적용하면 되는 건가요?

 css코드 작성하실 때 wrapper left랑 wrapper right 나누시고 난 후에wrapper left 바로 밑에 left header랑 left body로 세분화 하시던데 코드를 짤 때 알아보기 쉽게 하기 위해서 left 하위에 두신건가요? 아니면 저렇게 나눠야만 코드가 작동이 되는건가요?

java 버전을 확인해보니 1.7 이더라고요그래서 1.8 버전을 설치 하려고 yum unstall oracle-j2sdk1.8 했는데 다음과 같은 에러가 납니다. [root@server01 yum.repos.d]# yum install oracle-j2sdk1.8Loaded plugins: fastestmirror, refresh-packagekit, securitySetting up Install ProcessDetermining fastest mirrorsYumRepo Error: All mirror URLs are not using ftp, http[s] or file.

안녕하세요.강의를 듣던 중 궁금한 점이 생겨서 질문 드립니다.색상이나 스페이싱 등 다양한 스타일을 미리 지정해 두는데, 피그마 토큰에 등록 해두었으나, 디자인 작업이 끝날때까지 단 한번도 사용하지 않는 스타일값도 있더라구요.예를 들어 blue색상을 등록할 경우 총 9가지의 단계로 (blue 100 - blue 900) 지정하는데, blue 400은 사용되지 않는 그런 상황이 발생하더라구요. 물론 9단계든 5단계든 정해진 법칙이 있는건 아니지만, 이렇게 다양한 색상을 미리 지정해 두는 이유가 궁금합니다. 답변 부탁드립니다 !ㅎㅎ (강의 너무 유익하게 잘 듣고 있어용!!)

VC에서는 Pyside6를 설치해서 사용하고 있는데, Pycharm에서는 설치가 안되는 걸까요?

안녕하십니까. 궁금한 사항이 있어서 이렇게 질문 남기게 되었습니다. 14장에 waveform 그림 관련 질문 사항입니다. ff 이 3개 쓰였고, latency가 3cycle로 이해했는데, 그림은 2cycle만에 출력이 발생하는 것처럼 느껴져서 혼란이 조금 생겨서 죄송하지만 이렇게 질문을 남기게 되었습니다. 감사합니다.

일반적으로 train_test_split() 함수에 random_state를 지정하는 이유는 학습 데이터셋과 테스트 데이터셋을 분리할 때 매 수행마다 동일한 데이터셋으로 분리하기 위함이라고 알고 있습니다. 그런데 DecisionTreeClassifier()객체를 생성할 때 안에 random_state를 넣어주는 이유는 무엇인가요? DeicisonTreeClassifier과 train_test_split() 둘다 random_state를 넣어줘야 하나요? 만약 그렇다면 radom_state가 각각 사용되는 의미가 다른가요? 다르다면 어떻게 다른지 여쭙고 싶습니다. 선생님, 날씨도 더운데 답변해주시느라 너무 감사합니다ㅜㅜ

강의를 듣다 보면, 컨트롤러, 어댑터 서비스 리포지토리 등 인터페이스로 정의한 뒤에 실제 구현객체를 따로 두는 형태로 개발을 하고 있는데 MVC 강의를 들어보면 어댑터의 경우 createParamMap 이라는 공통으로 사용되는 메서드가 있는데, 어댑터 들은 어댑터 끼리 "의미있는 연관 관계"가 아니라 같은 기능을 하기 때문에 interface로 정의하는 걸까요? createParamMap같이 똑같이 사용되는 건 interface에 default 메서드나, 추상 클래스에 메서드로 사용하면 좋을 것 같은데, 이렇게 default 메서드로 구현하거나 추상클래스의 메서드로 구현하는 부분에서도 차이가 있을까요? 둘의 차이가 없다면, 왜 추상 클래스가 아닌 인터페이스로 정의하고 구현객체를 두는지 궁금합니다.

도메인 서비스와 응용서비스를 구분할 수 있는 조건이 무엇일까요?사내 프로젝트 마다 달랐고, 항상 경계가 모호해서 해당 프로젝트의 정책에 맞추어 개발했는데 이 부분에 대해 의견을 듣고 싶습니다.- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.

안녕하세요 강사님!필기와 복습을 위해 블로그에 강의 내용을 포스팅해도 될까요? 그리고 혹시 강의 중간 중간 나오는 사진들 (ex)defer, async 비교 막대 사진자료 등)도 함께 올려도 되는지 궁금합니다.강의가 정말 유익합니다. 감사드립니다.
