안녕하세요, 제가 다운로드 후 실행한 온라인 인스톨러는 qt-unified-linux-x64-4.5.2-online.run인데 다음과 같은 문의사항이 있습니다. 우분투에서 qt-unified-linux-x64-4.5.2-online.run을 실행했을 때 Latest supported releases로 필터링한 Qt 버전 목록 중 강의 슬라이드에 나온 6.0.1이 없습니다.6.5.0, 6.4.3, 6.3.2, 6.2.4, 5.15.2가 있는데 어떤 버전을 선택하면 될까요? 카테고리에서 Additional libraries가 Qt 버전별로 하위항목으로 들어가있고Qt 3D, Qt Image Formats, Qt Network Authorization뿐만 아니라 다른 여러 항목들도 있는데 모두 체크하면 되나요?Developer and Designer Tools 카테고리도 있는데 여기선 어떤 걸 선택하면 되나요?

안녕하세요 윈도우 OS 사용자입니다. 제가 VMware 가상머신을 이용해서 우분투를 설치했는데요 강의에서 진행하는 것들은 윈도우 환경이 아닌 가상머신 안에 있는 우분투에서 진행해야 되는 것인가요? 예를들어 강의를 따라가면서 코딩을 하거나, 코딩을 하고 깃허브에 올리는 작업들 모두 가상머신 안인 우분투 환경에서 진행해야 되는 것인지, 윈도우 환경에서 개발을 진행하다가 우분투 환경이 필요할 때 우분투를 이용하면 되는 건지 궁금합니다!

기존 우분투에 cuda 잡혀있습니다. 아나콘다 설치 후 가상환경 만들어 주고 가상환경쪽에도 cuda 잡아준 후 MMDetection 설치해야하는건가요?

안녕하세요 남박사님..   ubuntu 에서 docker설치 까지 진행한후 ... 강좌중   프로젝트를 docker 이미지로 만들어서 배포 내용중 10:11초까지 진행했는데요   강의 듣고있다가 컴퓨터 문제상 잠시 멈추고.. 재부팅을 하니까 portainer 웹사이트가 열리지 않은데.. 연결 시킬려고 하면 어떻게 해야할까요?   해당 아이피에 9000을넣고 실행해도 연결이 안됩니다. ..           docker의 볼륨을 만들어서 portainer를 실행시킬려고 해도.. 이미 있다고 나오는데.. 검색을 해도 잘안나오는거 같아서 여쭤봅니다..!

안녕하세요. 우분투 활용중에  fatal: destination path 'ardupilot' already exists and is not an empty directory. 라고 떠서 도저히 무슨말인지 서치해도 모르겠습니다 .ㅠㅠ 알려주세요ㅠㅠㅠㅠㅠㅠㅠㅠㅠ

아래와 같은 리눅스 쉘 스크립트구문을 파이썬으로 실행하고싶습니다.   #!/bin/bash   corpId="000466" time=`date +%Y%m%d%H%M%S` ct=$corpId$time   ## 평문 파일 생성 echo $ct > text_$ct.txt   ## 전자 서명 openssl dgst -sha256 -sign private.key -out text_$ct.sign text_$ct.txt   ## 전자 서명 -> base64 변환 openssl base64 -in text_$ct.sign -out text_$ct.sign.base64   파이썬으로 코드를 어떻게 적용 해야 할지 알고 싶습니다. 위와 같이 openssl 을 이용하여 전자서명 파일을 생성하고 생성한 전자서명 파일을 base64로 인코딩하는 파이썬 코드를 알려주시면 너무나도 감사하겠습니다.

- 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. 해당 강좌 환경 설정을 우분투로도 할 수 있을까요? (윈도우 환경만 가능한가요?)   우분투20.04 64비트 입니다.

독립적인 컴퓨터에 우분투가 설치되어 있는데, 독립적 pc의 우분투 환경에서 해당 온라인 수업을 진행하려고 하는데, 그럼 아마존ec2 에서 안해도 되는지 문의드립니다. (도커수업에 지장이 없는지 하여 의문/궁금사항이 있어서 문의합니다.)
