데이터 값을 넣어주지 못해서 movietitle 부분이 오류가 나는것 같은데 , MovieDetail 에 Favorite 부분 에서 넣어주지 못한거 같다고 생각이 듭니다. 어떤식으로 데이터를 넣어야 하는지 여쭤봅니다.    

알려주신대로 helm 으로 mysql을 설치 중인데  3 pod has unbound immediate PersistentVolumeClaims.    오류가 발생하면서 더 진행 되지 않습니다. 확인 부탁 드립니다.

지금에서야 듣는데 설치 에러가 자꾸 떠서 고민중에 버전을 최신버전으로 자동 설치한다면 어떨까라는 의문에 구글링하고 뒤에 버전 정보를 지우면 최신 버전으로 자동으로 찾아준다고 합니다 아래와 같이 requirements.txt를 변경했습니다 pandas numpy seaborn matplotlib finance-datareader ipython 완강까지 쉴새없이 달려보겠습니다!  

09:14초에 똑같이 코드 필사하면서 공부중인데 타입에러가 나오는데 무엇이 잘못된 것인가요??

  아래 같은 오류가 떠요... 오토컴플릿-파이썬 디스에이블 하면 아나뜨구요..왜이런걸까요..?     - 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.

강의 기한이 무제한이라고 되어있는데 완강을 했습니다 하지만 반복해서 듣고싶어서 듣고있었는데 갑자기 존재하지 않는 페이지입니다 이런식으로 나오면서 안들어가지네요.. 이러시는분 혹시 계신지, 아니면 원인이 뭔지 알고싶습니다

실행 시 메인페이지에서 오류납니다 ㅠ 

안녕하세요 열심히 수강하고 있는 수강생입니다. Local 환경에서 설치 하고 테스트 하다보니 회사 내 보안적인 이슈 때문에 테스트가 쉽지 않아 구글 클라우드 플랫폼 환경에서 VM을 이용하여 마스터 서버와 work 노드를 구성하려고 합니다. 알려주신 절차대로 수행 중에 kubeadm init를 수행하면 아래와 같은 오류가 발생합니다. 여러번 반복해 보았는데도 오류가 계속 발생되는데 도움이 될 만한 사항이 있으면 알려주세요.. ps) 내부적인 보안 때문에 네트워크 문제가 아닌가 의심은 가는데 어떻게 조치를 해야 되는지 알 수가 없네요. 감사합니다. ======================================================================== Hit:2 http://asia-northeast3.gce.archive.ubuntu.com/ubuntu bionic InRelease Hit:3 http://asia-northeast3.gce.archive.ubuntu.com/ubuntu bionic-updates InRelease Hit:4 http://asia-northeast3.gce.archive.ubuntu.com/ubuntu bionic-backports InRelease Hit:1 https://packages.cloud.google.com/apt kubernetes-xenial InRelease Get:5 http://security.ubuntu.com/ubuntu bionic-security InRelease [88.7 kB] Fetched 88.7 kB in 1s (72.9 kB/s) Reading package lists...

코드는 강의 따라 잘입력한거 같은데 getchar()  함수 이후 아무값이나 입력하고 나면 무조건 2번 반복되서 실행됩니다.. 대체 왜이런 현상이 일어나는건가요?? ㅠ

while 문에서 반복이 두번씩 나타납니다.. getchar()함수에서  아무키나 입력해서 넘어갈때마다 두번씩 반복되는데.. 왜그러는걸까요ㅠ

유니티도 다시 설치하고 , 업데이트 확인 , 외부환경에서 devenv.exe 연결도 해보고 , 선생님읰 코드를 다운받아도 안된디고 합니다. 혹시 제가 밑줄친 부분떄문인지....

좋은 수업 감사합니다. 패스파인더 관련 질문이 있습니다. melt 글씨에 녹는 표현을 하고 패스파인더로 합치니까 e와 l의 빈 공간이 글씨 색으로 채워지는데 이건 왜 이런 걸까요..?

Failed to read target status Debugger connection lost. Shutting down... 이라는 오류를 만나고 정상적으로 디버깅이 되지 않는 문제를 만났습니다. 해당 오류에 대해 구글링을 해봤지만, 마땅한 해결책이 나오지 않아 실습에 어려움을 겪고 있습니다. ST-LINK를 지웠다가 다시 설치해도 동일한 문제가 반복됩니다. CubeIDE의 'Build Analyzer'를 보니 빌드된 프로그램이 RAM을 18.35KB, flash는 17.3KB를 사용하는 것 같습니다. F103RB는 20KB SRAM과 128KB flash를 가지고 있고, L053R8은 8KB SRAM과 64KB flash를 가지고 있는데, 메모리 부족 때문에 디버깅 문제가 생기는 것일까요? Debug console 전문을 올립니다! 감사합니다! STMicroelectronics ST-LINK GDB server.

. 강의를 보면서 UL/UI_Button.cs를 지우고 수업자료를 다운 받아서 원래 있던자리에 UI_Button 스크립트를 넣었더니 이런 오류가 나옵니다. 어떻게 해야 하나요??

무엇이 오류인지 모르겠습니다 ㅠㅠ
