안녕하세요 선생님, 좋은 강의 감사합니다!!! 제가 직접 custom data를 활용해서 yolo v5를 직접 학습해보려고 합니다. cvc-14라는 적외선데이터셋으로 학습하려고 하는데 이 데이터셋은 annotation 모양이 사진처럼 되어있습니다. yolo v5를 사용해 bccd데이터 디텍션하는 예제보면 bccd데이터의 voc포멧을 coco로 변환하는건 이해했습니다. 근데 위의 annotation양식을 어떻게 coco로 바꿀 수 있을까요...? 검색해도 참고할만한 답이 나오지않아서.... 선생님께 한번 여쭤보고싶습니다. 감사합니다!!
cmd창에서 I love apple. 출력해보는 실습을 진행하였는데 강의에서 해주신 방식과 똑같이 실습을 진행하였는데 exe 실행파일을 cmd창에서 입력하고 enter를 눌러서 출력을 기다리니 줄바꿈 후에 깜빡이기만 하고 출력이 되지 않고 a를 입력해보니 ascii 코드값(?)인지는 모르겠지만 97과 10이 출력이 됩니다. 어떻게 해야하나요??

안녕하세요. vs code로 python 공부하다가 파란줄이 생겨서 없애고 싶은데 아무리 구글링에서 찾은 방법을 적용해도 없어지지가 않아요. 구글링 방법 python pylint 적용하기, python 버전을 내가 쓰고 있을 걸로 맞추기 이렇게 해봤는데도 안 되네요.. 어떻게 없애나요?
1번 5번 제가 이해한게 맞나요? 스토리지 게이트웨이는 마이그레이션이 맞긴한데 첫 마이그레이션 이후 온프레미스와 aws 스토리지를 연결해 줘서 데이터 저장 용량을 늘리고 자주 쓰는 데이터를 캐싱해서 빠른 엑세스를 제공하는 연결의 느낌이 크고 datasync는 온프레미스와 aws 스토리지 간에 direct connect 로 연결하여 온프레미스에서 파일을 업로드 하면 자동으로 aws 스토리지에 업로드 되는 규칙인가요?
쓰러트릴때 사용했던 1번 for (const item of intersects) { if (item.object.cannonBody) { item.object.cannonBody.applyForce( new CANNON.Vec3(0,0,-100), new CANNON.Vec3(0,0,0) )}; // } 2번 if (intersects[0].object.cannonBody) { intersects[0].object.cannonBody.applyForce( new CANNON.Vec3(0,0,-100), new CANNON.Vec3(0,0,0) )}; 이 두 가지 코드를 직접 동작시에 위의 for문 코드가 클릭을 여러번 했을시에 더 빠르게 움직이는 것은 1번 코드가 조금더 성능이 좋다고 봐도 되는걸까요 ? 추가적으로 1분코딩님의 홈페이지의 축구공처럼 화면을 회전함에 따라서 주는 힘의 방향을 다르게 하고 싶을때 applyForce 부분의 기준점을 변경하면 될 것 같아서 시도해보았는데 잘 모르겠어서 이렇게 질문드립니다..
Bright and energetic, Her Blossom is a love letter to London in bloom. A walk through sunshine-soaked parks and down blossom-covered paths, it's the embodiment of the Londoners attitude in those first few days of spring - high-spirited, spontaneous and full of anticipation for the season ahead.

하이퍼 파라미터 튜닝 기법 적용하기 (SVC 실습) 강의 12분 19초 해당 부분에서 SVC( random_state = 1 ) 와 같이 random_state 를 지정해주는 부분이 있는데요. 기존에 제가 가지고 있던 생각은 SVC 모델의 경우 학습데이터에서 랜덤하게 샘플링해서 학습하는 게 아니라 학습데이터를 통째로 활용하는줄 알았거든요.. 혹시 SVC 모델이 decision boundary 를 결정할 때 학습데이터를 통으로 사용하는 것이 아니라 bootstrap 방식처럼 전체 학습데이터에서 랜덤하게 샘플링한 데이터를 활용하기에 random_state 옵션이 따로 있는 것인가요? 답변 부탁드립니다. 감사합니다. :)
