안녕하세요. 제목대로 intellij 터미널이 현재는 zsh 로 되어 있는데 외부 어플인 warp 로 변경하는 방법 좀 알려주시면 감사하겠습니다. 꾸우벅~~

안녕하세요 강사님 항상 수업 잘 듣고 있습니다! 10강 DataSource 자동구성클래스 수업 실습을 따라하면서 오류가 발생했는데 원인을 못찾아서 질문드립니다! Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.NullPointerException

실리콘밸리 엔지니어가 가르치는 파이썬 장고 웹프로그래밍
sqliteBrowser 사용하는 수업에서 db.sqlite3를 열려고 하니, database is locked 라는 메시지가 뜹니다. 그래서 ChatGPT나 Bard... Googling을 이용해봤지만, 저에게 해당될만한 내용이 없네요. 혹시 몰라 재부팅도 해봤습니다. 이거 DB부분만 지웠다가 다시 까는 방법이 있을까요? (makemigrations, migrate 부분)

[퇴근후딴짓] 빅데이터 분석기사 실기 (작업형1,2,3)
안녕하세요 선생님 현재 모델링 및 평가(회귀)부분을 학습하고 있습니다. 코드를 따라가면서 실습을 진행하고 있는데, rmse 값이 선생님과 달라 질문 드립니다. 제가 알기로는 모델링을 하는 과정에서 예측한 값이 달라질 수 있고, 이에 따라 평가지표인 rmse 값이 다를 수 있다...라고 알고 있습니다. 그런데 값의 차이 뿐만이 아니라 baseline과 scaler 적용 결과가 좋은지 나쁜지가 달라 질문드립니다. 예를 들어, 선생님께서 하셨을때는 RandomForestRegressor의 baseline이 rmse값이 가장 좋았고(작았고), scaler를 적용했을 때 rmse가 커져서 scaler 적용은 하지 않는게 좋다~라는 내용의 실습이었는데 제가 했을 때는 baseline의 rmse보다 scaler를 적용했을 때의 rmse가 작아 scaler를 적용하는 것이 좋다..는 결론이 나옵니다. 질문을 정리하자면, 모델링을 하는 과정에서 선생님과 제가 실습한 예측값과 rmse가 다른게 맞는지 다른게 맞다 해도 scaler 적용여부 등을 바꿀 수 있을 정도로 예측값과 rmse가 달라질 수 있는지 (추가질문)달라지더라도 선생님 실습값 : 4728.xx 제 실습값 6025.174022213681 이정도로 달라질 수 있는지... (추가질문) 모델링 및 평가(회귀) 24:56에서 수험자는 알 수 없는 영역>y_test로 rmse로 구하시고 결과값이 17909.xx로 나왔는데 여기에서도 charges에 로그변환 한 이후기 떄문에 원래는 np.exp(pred)로 rmse를 구했어야 하는지 일 것 같습니다. 감사합니다.

spring 명령어를 쳐서 확인하려는데 오류가 발생했습니다. 이 버전의 Java Runtime은 최대 55.0까지의 클래스 파일 버전만 인식한다고 합니다. Java SE 11 = 55이란거 까진 알았는데 그 다음에 어떻게 해야 될까요? 고민과 검색 많이하다가 답이 안나와 여쭤봅니다.

토비의 스프링 부트 - 이해와 원리
안녕하세요. 단위 테스트를 작성하여 확인한 후, 통합 테스트를 진행해보고 있습니다. 궁금한 점은 통합테스트 실행시 단위 테스트들이 실행되지 않는 다는 것인데 별도의 설정이나 콜이 필요한가요? 제가 이해한 바로는 @SpringBootTest 가 붙은 통합테스트 진행시 @Test가 붙은 단위 테스트들을 contextload()에서 자동으로 실행 되는 것으로 알고 있습니다. 현재 SpringBootTest쪽에는 별도의 코드가 있진 않고 빈 contextload()만 존재합니다. 조언 부탁드리겠습니다. 감사합니다.

[리뉴얼] 처음하는 파이썬 백엔드와 웹기술 입문 (파이썬 중급, flask[플라스크] 로 이해하는 백엔드 및 웹기술 기본) [풀스택 Part1-1]
위에 코드와 같이 웹서버를 열 때 처음 실행만 정상적으로 뜨고 두 번째부터는 로드중으로 계속 화면에 아무것도 안 뜹니다. 주피터 노트북과 아나콘다 프로그램을 완전히 종료하고 다시 접속해 위에 코드를 입력하면 다시 처음만 정상실행되고 두번째부터는 무한로드중으로 뜹니다. 다른 컴퓨터로 실행해봤을 때는 정상적으로 화면에 출력되는 것을 확인했고 제 노트북만 이러네요. 이거 때문에 아나콘다도 다시 설치해보고 윈도우에 내장되어 로컬호스트 주소도 확인하고 윈도우도 재설치해보고 컴퓨터 자체를 포맷해봤는데도 계속 같은 증상이네요. 혹시 문제가 무엇일까요? 이거 때문에 수업 진도를 못 나가고 있어요. 도와주세요ㅠㅠ

안녕하세요 colab을 이용하던 도중에 갑자기 이상한 현상이 생겨서 질문 남깁니다! 영어를 사용하면 별 문제가 없는데 이상하게 한글만 사용하면 글씨색도 변하고 위의 사진 처럼 셀의 화면이 내려가거나 확대 됩니다. 주석뿐만 아니라 코드에도 한글을 넣으면 똑같은 현상이 발생합니다. 작성시에는 화면이 보이지 않지만 작성후 방향키나 공백을 넣으면 다시 원래 화면으로 돌아옵니다. ㅠㅠㅠㅠ 너무 거슬려서 주석을 작성 할 수 가 없습니다ㅠㅠㅠ 해결책이 있을까요 이것저것 옵션 다 만져봤지만 해결이 안돼서 여쭙니다.

토비의 스프링 부트 - 이해와 원리
안녕하세요 토비님. 우선, 감동으로 청강을 이어갈 기회를 얻게되어 참 감사드립니다. 아래는 섹션8 - DataSource 자동 구성 클래스 파트의 @Bean 메서드 등록과정에 생긴 문제입니다. 의문점은 메서드 선언 순서에 영향을 받는다는것을 알게되서 다음처럼 2번의 테스트를 진행했습니다. @Bean 메서드 선언순서 에 따른 등록 테스트 simple , hikari hikari, simple 1 결과: simple 이 등록됨 /* DataSourceConfig.java */ @Bean @ConditionalOnMissingBean public DataSource simpleDriverDataSource() { ... } @Bean @ConditionalOnMissingBean @ConditionalMyOnClass("com.zaxxer.hikari.HikariDataSource") public DataSource hikariDataSource() { ... } hikari 에 `@ConditionalMyOnClass` 가 있기때문에 등록될 것으로 예상했지만, simple 이 등록되었습니다. 2 결과: hikari 가 등록됨 @Bean @... public DataSource hikariDataSource() { ... } @Bean @... public DataSource simpleDriverDataSource() { ... } 기묘하게도 @Bean 메서드 선언순서를 바꾸니 Hikari 빈이 등록되었습니다. 이상하다 싶어, @Primary 와 @Order(n) 을 주고 다시 테스트 해봤지만, 영향을 주지 않았습니다. 질문: 위와 같이 @Bean 메서드 순서에 영향을 받는 이유가 궁금합니다. 이 결과로 @ConditionalOnClass 의 인식되는 FQCN 의 조건을 바꿔보기도 하고, 위치도 바꿔봤는데, 이렇다할 동작방식을 파악하기 힘들었습니다. 그리고 @Primay 나 @Order 를 붙여가며 추가적인 등록순서에 대해 테스트를 진행했으나, 이것들 역시 영향을 주지 않았습니다. 여러 곳에서 알아본 바, @Bean 메서드는 등록순서에 영향을 주지 않는것으로 알고있었는데, 이런 경우에는 어떤 매커니즘이 동작하는지가 궁금합니다. 이 결과를 보고 생각에 혼란이 와서 질문을 드리게 되었어요. 혹시 제가 놓친것이 있다면 조언을 부탁드려도 되겠습니까? 읽어주셔서 감사합니다☺️
