안녕하세요, 기상청 기온정보 크롤링 관련 질문이 있습니다. 현재 기상청 접속 URL 이 아래와 같이 변경된 것으로 보입니다. https://www.weather.go.kr/w/obs-climate/land/past-obs/obs-by-day.do?stn=108&yy=2021&mm=12&obs=1 또한 태그 구조나 명칭도 변경된 것 같은데 weather_info로 클래스 가져오는 부분에 넣어야 할 클래스명은 아래와 같이 over-scroll 이라는 이름으로 변경하는 것으로 생각했습니다. weather_infor = soup.select(".over-scroll") 위와 같이 변경해봤습니다. 위 조건에서 weather info를 확인해보니 다음과 같았습니다. 강의에서 나온 태그 구조나 클래스 이름이 모두 변경된 것 같아서 예를 들어 기상청 사이트에서 21년 12월 1일의 태그 형식이 아래와 같습니다. 위의 조건에서 아래 코드를 실행하면 강사님 결과와 같은 결과가 나오지 않습니다. 아래 코드는 진행에 문제가 있었습니다. # 기온정보 list_climate_info = list () # 일자정보 list_day_info = list () for day_weather in weather_info : # 작업 1. 공백문자 제거 if ( day_weather.get_text () .isspace () != True ): # 작업 1-1. 기온정보 if ( day_weather.get_text () .find ( "평균기온" ) == 0 ): list_climate_info.append ( day_weather.get_text ()) # 작업 1-2. 일자정보 else : list_day_info.append ( day_weather.get_text ()) 제가 변경한 조건에서 위 코드를 실행하면.... 아래와 같이 동일한 결과가 아닌데 어떻게 변경해야할지 모르겠습니다. 도움을 부탁드립니다.
강의내용에서 커밋된 읽기 방식을 많이 들 사용한다고 하시는데 정작 제가 재직중의 회사의 경우 커밋되지 않은 읽기 방식을 채택중에 있습니다. 지금까지 아는 봐로는 커밋되지 않은 읽기 방식을 채택할경우 SEELCT면에서 데이터를 빨리 읽을 수 있기 때문에 사용하는 것으로 인지하고 있습니다. 대용량 데이터를 다루는 케이스에서는 커밋되지 않은 읽기 방식은 적당하지 않은 방식일지 궁금합니다.
안녕하세요 선생님! 그동안 그냥 강의 설렁설렁 듣다가 한 번 시험을 보고자 해서 SA 시험을 등록했습니다. 쭉 공부하고자 하여서 그런데 혹시 강의교안 전체 합친 pdf가 있다면 받을 수 있을까요? 그리고 이 강의랑 중상급자 강의 모두 가지고 있는데, 두 강의를 열심히 학습하면 SA시험 합격할 수 있는 정도는 될까요? (물론 기출문제를 열심히 풀기+알파 가 필요하겠지만요...)
안녕하세요. 강의의 yolo 파트를 혼자 수강하고, 스스로 추가 실습으로 현재 real time detection의 sota인 YOLOR을 혼자 독학하고 있습니다. 5일 간 train evaluation에서 에러를 수정하지 못해서, 혹시나 하는 마음에 이렇게 도움을 요청해봅니다. https://drive.google.com/file/d/1mNBu7aLV61pdet9X2dE2uGiacxFbKpAo/view?usp=sharing 현재 제가 작업하고 있는 colab파일인데, train까지는 문제 없이 잘 진행 됩니다. 근데 test.py를 통해서 mAP 값을 구하려고 하는데, 자꾸 에러가 뜨고, 아무리 구글링하고 찾아봐도 방법을 모르겠습니다. ! python test . py --data . /test . yaml --weights /content/drive/MyDrive/best . pt --img 416 --device 0 으로 실행시키면 Namespace(augment=False, batch_size=32, cfg='cfg/yolor_p6.cfg', conf_thres=0.001, data='./test.yaml', device='0', exist_ok=False, img_size=416, iou_thres=0.65, name='exp', names='data/coco.names', project='runs/test', save_conf=False, save_json=False, save_txt=False, single_cls=False, task='val', verbose=False, weights=['/content/drive/MyDrive/best.pt']) Using torch 1.7.0 CUDA:0 (Tesla T4, 15109MB) Model Summary: 665 layers, 36843816 parameters, 36843816 gradients, 80.379953800 GFLOPS WARNING: --img-size 416 must be multiple of max stride 64, updating to 448 Scanning labels valid/labels.cache3 (202 found, 0 missing, 70 empty, 0 duplicate, for 272 images): 272it [00:00, 21758.26it/s] Class Images Targets P R mAP@.5 mAP@.5:.95: 0% 0/9 [00:01<?, ?it/s] Traceback (most recent call last): File "test.py", line 330, in <module> save_conf=opt.save_conf, File "test.py", line 226, in test plot_images(img, output_to_target(output, width, height), paths, f, names) # predictions File "/content/yolor/utils/plots.py", line 108, in output_to_target return np.array(targets) File "/usr/local/lib/python3.7/dist-packages/torch/tensor.py", line 630, in __array__ return self.numpy() TypeError: can't convert cuda:0 device type tensor to numpy.

현재 그룹 조회 API를 구현하고 있습니다. 메신저 앱 처럼 그룹 조회시 그룹 아이디, 그룹 이름, 그룹 이미지, 그룹에 속해있는 멤버들 (컬렉션)을 조회해 와야합니다. 여기서 강의의 V3 내용처럼 1 + N 문제를 해결하기 위해서 다음과 같이 페치 조인을 사용하여 쿼리문을 작성하였습니다. TeamRepository.java @Transactional(readOnly = true) public interface TeamRepository extends JpaRepository<Team, Long> { @Query("select distinct t from Team t" + " join fetch t.id id" + " join fetch t.groupName gn" + " join fetch t.imageUrl iu" + " join fetch t.teamMembers tm" + " join fetch tm.member m" + " where tm.id = :id") List<SearchGroupResponse> findGroupInfoWithMembers(@Param("id") Long id); } `Team.java` @Entity @Getter @NoArgsConstructor(access = AccessLevel.PROTECTED) public class Team extends BaseEntity { @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "member_id") private Member member; @Column(length = 30) private String groupName; @Lob private String imageUrl; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "place_id") private Place place; @OneToMany(mappedBy = "team", cascade = CascadeType.ALL) private final List<TeamMember> teamMembers = new ArrayList<>(); private LocalDateTime date; } TeamMember.java @Entity @Getter @Table(name = "GroupMember") @NoArgsConstructor(access = AccessLevel.PROTECTED) public class TeamMember extends BaseEntity { @ManyToOne(fetch = LAZY) @JoinColumn(name = "member_id") private Member member; @ManyToOne(fetch = LAZY) @JoinColumn(name = "team_id") private Team team; @Column(length = 100) private String curLocate; private char arrived; public TeamMember(Member member, Team team) { this.member = member; this.team = team; } } 강의 V3-1 과 같이 컬랙션 데이터는 지연 로딩과 BatchSize를 적용하여 성능 최적화를 해줘야 된다고 배웠지만 일단은 V3를 적용해 보고 개선해 보고자 이렇게 코드를 작성해 보았습니다. 하지만 다음과 같은 에러가 발생하였고 이를 해결하고자 여러 구글링을 해보았지만 해답을 찾지 못하여 질문 남겨봅니다. org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'promiseController' defined in file [/Users/sanha/SpringStudy/promisor/out/production/classes/promisor/promisor/domain/promise/api/PromiseController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'promiseService' defined in file [/Users/sanha/SpringStudy/promisor/out/production/classes/promisor/promisor/domain/promise/service/PromiseService.class]: Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'teamRepository' defined in promisor.promisor.domain.team.dao.TeamRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Invocation of init method failed; nested exception is org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract java.util.List promisor.promisor.domain.team.dao.TeamRepository.findGroupInfoWithMembers(java.lang.Long)!

강사님 안녕하세요, #메인 시작 영역에 관해 질문드립니다. main( ) 함수 실행시 if __name__ == "__main__" 영역 밖에서 실행했을 때 Runtime Error가 발생하던데, 왜 그런지 알고 싶습니다. (Threading에서는 if __name__=="main" 영역 밖에서 실행했을 때 정상적으로 작동하는 것 같은데 말입니다) 아래 전체 코드 드립니다. 감사합니다. from multiprocessing import Process import time import logging def process_func(name): print(f"subprocess {name} stated") time.sleep(3) print(f"subprocess {name} stated") def main(): format = "%(asctime)s: %(message)s" logging.basicConfig(format=format, level=logging.INFO, datefmt="%H:%M:%S") # 함수 인자 확인 p = Process(target=process_func, args=('First',)) logging.info('Main_process : before Creating') p.start() logging.info('Main_process : Sub Process stated') logging.info(f'Main_prcess : Status: {p.is_alive()}') p.join() logging.info(f'Main_prcess : Status: {p.is_alive()}') logging.info('Main_process : Sub Process finished') # if __name__=="__main__": main()
안녕하세요 질문이 하나있습니다. 1:40 부터 잠깐 보시면 new AnnotationConfigApplicationContext(AppConfig.class); AnnotationConfigApplicationContext에 파라미터로 넘긴 값은 스프링 빈으로 등록된다고 하셨는데(AppConfig.class ) AppConfig 이 class는 이미 @Configuration 이 붙어있어서 스프링 빈으로 등록 되어 있는 상태 아닌가요 ?? @Configuration public class AppConfig {..}
[질문 템플릿] 1. 강의 내용과 관련된 질문인가요? (예) 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예) [질문 내용] 여기에 질문 내용을 남겨주세요. 강의내용대로 @Transactional 넣고 스프링부트띄워서 테스트를 돌리면 rollback이 바로되는게 아니라 좀 지나서 되는것 같더라구요 회원가입 테스트 돌리고 디비에서 member조회 해보면 인서트가 되어있고 한번더 조회하면 그때 사라지더라구요 그것 때문에 회원가입과 중복회원 따로 돌리면 되긴하는데 전체 테스트를 돌리면 중복회원예외에서 실패가 납니다. 어떻게 해야될까요..?
이런식으로 Order 가지고 있는 count가 5보다 작은것만 조인 필터링을 하고싶은데 실제로 쿼리를 실행해보면 count가 5이상인 Order를 가지는 Delivery도 같이 조인되서 List에 반영됩니다. 쟤가 외부조인이랑 조인필터링이라는 걸 잘못 이해하고 있는지가 궁금합니다. 아니면 오더랑 딜리버리가 일대일관계에서 생기는 문제인지가 궁금합니다!
Delivery 와 Order 를 일대일관계로 매핑하고 둘다 지연로딩을설정했습니다 "select d from Delivery d left join d.order" 해당쿼리를 쏠때 조인쿼리를 날린후 추가로 오더 select 쿼리를 날리는데 이게 일대일 관계에서 정상적인지 궁금합니다!
안녕하세요! 강의에서 설정 정보를 사용하면 "스프링 빈이 스프링 코드에 의존하지 않는다"라고 말씀해주셨는데요. @Bean이 있어 스프링 코드를 사용해야 하는 환경인데, 스프링에 의존하지 않는다는 게 어떤 의미인지 한 번에 잘 이해가 가지 않습니다. import org.springframework.beans.factory.annotation.Autowire ; @Bean에 들어가보면 위와 같이 springframework를 임포트하는데, 이래도 스프링 코드가 아닐 수 있나요? 아니면 이 정도 코드는 스프링이 없어도 작동하는 건가요? 추가 설명 부탁드립니다! 감사합니다.
안녕하세요. 강사님. 저는 iOS 개발자로 일하다가 지금은 웹개발자로 일하면서 MS SQL을 사용하게 된지 얼마 안된 개발자입니다. 먼저 유용한 강의 진심으로 감사드립니다! 강의를 듣다가 문의사항이 있어서 남겨드립니다. 현재 2강의 "테이블 값 생성자 VALUES, DML + TOP" 강의를 듣고 있는데, MERGE 예제에서 AdventureWorks라는 DB를 사용하는데, 수업자료에는 AdventureWorks에 대한 DB를 찾아볼 수 없어서요. 혹시, 어딘가 있는데 잘 못찾고 있는 것인지, 아니면, 제가 잘 몰라서 그러는 것인지 답변 부탁드리겠습니다!
강의를 보며 개발자님과 똑같이 하지 않고 저에게 필요한 부분들을 제 스타일대로 바꾸면서 듣고 있습니다. 잘 되다 이번에 문제가 생겼습니다. 현재 레이아웃이 겹칩니다.. 어느 부분의 코드를 보여드리야할까요.. 추가적으로 어떤 걸 말씀드려야하는지 알려주시면 더 자세하게 질문하겠습니다. 도와주세요

안녕하세요 현영님. 에러는 해결을 한 상태인데 궁금한 점이 생겨 질문드립니다. const fs = require ( ' fs ' ); 백쪽에 fs모듈을 쓰면서 부터 시작됐는데, 강의 마지막 부분에 와서 프론트 서버를 새로고침하니 저런 에러가 발생했습니다. 스택오버플로우를 찾아보니, https://github.com/vercel/next.js/issues/7755 프론트쪽에 next.config.js라는 폴더를 생성한 후 module . exports = { webpack : ( config , { isServer } ) => { // Fixes npm packages that depend on `fs` module if ( ! isServer ) { config . node = { fs : 'empty' } } return config } } 이런식으로 넣어주라는데, 프론트 서버에서는 fs모듈에 관련된 작업을 한 게 없어 여러가지 테스트를 하다가, 프론트 폴더의 .eslintrc파일에 extends를 airbnb가 아닌 주석처리된 부분으로 바꾸니 또 해결이 되었습니다. (다른 프론트나 백쪽의 코드는 수정이 없었습니다) 1. 혹시 extends랑 상관이 있는건지? 아니면 그냥 일시적인 에러라고 생각을 하면 될까요? 2. 관련이 없다고 하면 혹시나 알 수 없는 에러가 나올 경우 현영님의 경우 어떻게 대처를 하시나요? (에러가 생길 때마다 기록을 해두는 편인데 생각보다 찾기가 힘든? 에러들이 종종 나오더라고요.. 짬의 차인지..?) ++ 어제 업데이트 하신 정보들 확인했습니다. 바로바로 업데이트 해주셔서 불편함이 없네요 감사합니다
