- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 #include 쪽에서 오류가 있는 것 같아요. 선생님께서 입력하신 것과 똑같이 입력했는데 왜 오류가 발생할까요? 제가 2017버전이 아니라 2019버전을 다운받아서 그런걸까요? 2017버전을 다운받으려고 찾아봤는데 위와 같이 너무 다양한 버전들이 있어서 뭘 다운받아야 할지 모르겠어요. 그래서 일단 2019로 다운받았는데 문제가 될까요? 그리고 어떤 버전을 다운받아야 하는지 알려주시면 감사하겠습니다.

안녕하세요. 하나씩 해결하면서 재밌게 하고 있습니다. 질문이 server03 이 아래와 같이 잘 인식이 안됩니다. 혹시 다른것을 해줘야 할까요. 가상서버 01부처 03까지 모두 설정하고 잘 돌아가는 상황입니다. 가이드 부탁해요. 알수가 없네요.

안녕하세요 인피니트 스크롤 적용 중 이상한 점이 하나 있어서 질문드립니다. f12누르고 개발자 모드 킨 상태로 redux 툴로 action을 체크하는 상태에서 스크롤을 맨 밑으로 내리면 제로초님처럼 LOAD_POSTS_REQUEST를 보내고 SUCCESS까지 동작하는데 문제는 스크롤이 계속 맨 밑에 머물러서 REQUEST SUCCESS를 계속 반복합니다. 즉 한번 맨 밑으로가면 스크롤이 다시 올라오지 않고 그 상태에서 REQUEST, SUCCESS를 5번 반복합니다. 그런데 개발자모드를 키지않고 테스트하면 제로초님처럼 정상작동합니다. 이거는 별 문제가 아닌건가요? (코드도 깃허브참고해서 똑같이 했습니다.)

CVAT툴을 활용해서 Custom 데이터를 학습시키려고 합니다. 울트라욜로를 통해 detect.py를 통해 검출된 이미지가 결과물로 나오는데,  결과내용을 소스, 또는 txt(검출클래스,박스위치) 등으로 볼수있는 방법이 있을까요? (검출할 객체가 1개여서 이미지내에 해당 객체가 있는지 O/X로만 받으면 되는데, 이미지로 결과가 나와 당황스럽네요) opencv같은경우 결과를 소스에서 확인가능하지만, 커스텀 데이터학습 모델을 쓰려면 weight에 pt파일을 넣고, cfg는 기존 yolo v3것을 쓰면 되는것인지 모르겠습니다.

테이블에 추가 삭제기능을 넣어 추가 버튼을 클릭하면 자동으로 테이블 맨아래에 컬럼이 늘어나게 만드는 방법이 있을까요? 반대로 삭제도 가능한 방법이 있나요? + 추가적으로 텍스트 필드에 예를 들면 1이라는 글을 작성했을때 단위 도씨(℃)가 뒤에 고정적으로 작성될 수 있는 방법이 있을까요?

안녕하세요. 강의 잘 듣고 있습니다. 다름이 아니라, 상품을 등록하고 상품 목록에서 새로운 상품을 등록한 것을 새롭게 갱신 해야되는데 갱신이 안돼서 질문드립니다. log를 통해서 form을 찍었는데도 데이터가 저장되지 않습니다. 굉장히 기본적인거에서 틀린거 같은데 잘 안보이네요.. 일단 첫번째 사진은 갱신이 되지 않고 계속 저렇게 목록이 뜹니다.

안녕하세요 제로초님! 서버의 크롤러가 크롤링을 진행하는 과정이 주어진 url에 먼저 request를 보내서 html문서를 내려받고 그 다음에 meta 태그를 분석하는 것이 맞나요?? 아니면 다른 방법이 있는건지 궁금합니다.

- 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. 저는 macOs에서 vm을 실행시켜서 사용하고 있는데요 mac에 있는 host-file.txt에 server01,02,03의 ip도 추가해주었고 강의에 나와있는 대로 NAT주소와 호스트 네트워크 관리자 주소도 설정해주었습니다. 하지만 server01, server02를 vm에서 가동한 후, 크롬에서 server01.hadoop.com:7180에 접속해도 계속 접속이 되지 않습니다. mac 같은 경우에는 설정이 다른 부분이 있나요? 아니면 제가 어떤 과정을 추가적으로 더 해야되는 부분이 있나요? +) server01, server02에 로그인은 잘 됩니다.

안녕하세요 지방대 게임공학과 4학년에 재학중인 학생입니다.  클라프로그래머를 희망하고 있는데 서버 쪽에도 관심이 있어 현재 클라를 중점으로 하고 서버 공부도 같이 병행하고 있습니다.  그런데 한 가지 걱정인것이 그래픽스 지식 관련인데요. 학부 2학년에 그래픽스 수업에서 OpenGL 수업을 들었습니다.  그때까지만 그래픽스 지식이 왜 필요할까 라는 안일한 생각을 했던 터라 간단한 도형만 그려보고 수업을 대충 들었습니다.  핑계이지만 그 뒤로 그래픽스 지식을 공부하지 않았습니다. Rookiss 님이 생각하시기에 그래픽스 지식을 쌓으려면  어떤 방식으로 공부하는 것이 좋은지 궁금합니다. 추천할 만한 책이 있는지, 추천할 만한 강의가 있는지 알려주시면 정말 감사하겠습니다. 

안녕하세요 수업 너무 잘 듣고 있습니다 마지막 git에 파일 올리는데 문제가 있어 문의드립니다  .gitignore 파일에 dev.js 입력하고 파일을 올렸는데 Git에서 config파일에 dev.js 파일이 숨겨져 있지 않고 그대로 나와있어서 어떻게 하면 좋을까요?

- 저 부분이 에러가 나는데요. 모든 임포트는 정상적으로 했고 경로도 제대로 잡혀있어요 .. .

카메라가 플레이어를 계속 조준할때 두 스크립트의 Update가 겹쳐서 플레이어가 버벅거리듯 출력되기에 카메라 스크립트의 update를 LateUpdate로 변경해서 제일 마지막에 update 시키는건 강사님 덕분에 명확히 이해됐습니다. 한가지 궁금한건, 유니티 문서에서 이벤트 순서를 보여주셨을 때, update()와 lateupdate()의 훨씬 이전에 fixedUpdate()가 제일 먼저 작동하는것으로 나와있던데, 만약 카메라를 일반 Update()로 사용하고 카메라의 타겟인 플레이어의 움직임을 FixedUpdate()로 사용할 경우 어떤 문제가 발생할 수 있나요? FixedUpdate()가 물리연산에 사용된다는 설명은 들었지만, 아직 물리적인 부분을 안 만져봐서 그런지 정확히 어떤 문제가 생길지 잘 와닿지 않아서 질문을 남겨봅니다.

안녕하세요. 너무나 잘듣고 있습니다. 해당문제를 다익스트라 알고리즘을 활용해서 풀었습니다. 다익스트라의 for-loop안에서 이런 조건을 넣었습니다. if (갱신할값 (dist[next])< min(지금까지의 최솟값, 현재 간선의 값)) {             dist[next] =  min(지금까지의 최솟값, 현재 간선의 값)             ..... } 우선순위 큐는 맥스힙으로 현재까지의 최솟값의 최댓값을 항상 맨위로 보냈습니다. 혹시 다익스트라를 사용하면 안되는 이유가 있나요? (코드가 조금 더 간편해보여서 질문드립니다. 그 전 강의에서 다익스트라를 강의 해주셔서 알고 사용했습니다. )통과를 받기는 했습니다. 감사합니다.

회사에서 ubuntu 를 사용하다보니  ubuntu로 실습을 따라 하려고 하는데 두 os 간에 차이가 클까요?

안녕하십니까. 해당문제의 조건에 양방통행 도로라는 조건을 추가해주시면 좋겠습니다. 감사합니다.

안녕하세요. 송아지가 웅덩이에 있는것이 테스트케이스에 있는거 같습니다. 해당내용을 문제의 조건에 추가해주십시오. 감사합니다.
