안녕하세요, 강의 잘 듣고 있습니다. 다름이 아니라 Seaborn으로 barplot을 그리는 와중에 문제가 생겼습니다. 평당분양가격도 float64가 맞는데 무엇이 문제일까요? 각 패키지 버전은 아래와 같습니다. Seaborn => 0.10.0 matplotlib => 3.1.3 Python => 3.7 pandas => 1.0.1 Anaconda => 32bit 감사합니다!

미해결it 취업을 위한 알고리즘 문제풀이 입문 (with C/C++) : 코딩테스트 대비
벨만포드 알고리즘
안녕하십니까 좋은 강의 감사드립니다. 벨만포드 알고리즘코드 관련하여 질문이있습니다. for(i=1; i<n; i++){ for(j=0; j<Ed.size(); j++){ int s=Ed[j].s; int e=Ed[j].e; int w=Ed[j].val; if(dist[s]!=2147000000 && dist[s]+w<dist[e]){ dist[e]=dist[s]+w; } } } 여기서 바깥 for문이 i에 따라 1일때는 한번만에 가는 경우, 2일 때는 두번만의 가는 경우 ..... n-1번만에 가는경우 라고 설명 해 주셨는데 바깥 for문이 없더라도 안 쪽 for문 만으로 n-1번만에 가는 경우를 다 따지는 거 같은데 혹시 제가 잘못 이해한 것 인지... 입력이 vertex number 순으로 순차적으로 받게 되는데 예를들어 i가 1이고 안쪽 for 문을 j가 1일때 돌며 1->2 가는 것을 추가하여서 dist[2]=x를 넣게되면 그다음 j가 2가 될때는 dist[2]!=2147000000 조건에 걸리지 않게 되고 2에서 가는 경우의 수를 검토하게 되는데 그렇게 되면 이것은 두번만에 가는 경우가 되는것이 아닙니까??

User.js 에서 this
userSchema.pre("save", function (next) { var user = this; if (user.isModified("password")) { bcrypt.genSalt(saltRounds, function (err, salt) { ... var user = this 를 하면 user 에는 뭐가 담기게 되는거죠?ㅠㅠ 또 여기서 var user = this 를 선언을 했는데 userSchema.methods.generateToken = function (callback) { var user = this; var token = jwt.sign(user._id.toHexString(), "secretToken"); ... 왜 여기서 또 선언을 하는 거에요? User.js 에서 user 이라는 변수가 뭔지 정확히 모르겠습니다ㅠㅠ

미해결자바 ORM 표준 JPA 프로그래밍 - 기본편
Transactional 문의 드립니다.
안녕하세요 테스트 돌릴때는 정상적으로 인서트 및 @Transactional를 활용한 롤백 등 의도 동작이 되는데 API의 JSON 형태로 던지면 javax.persistence.TransactionRequiredException: No EntityManager with actual transaction available for current thread - cannot reliably process 'persist' call 의 경우가 발생 하는데 어떤 문제인지 힌트좀 주실 수 있을까요.. EntityManagerFactory emf = Persistence.createEntityManagerFactory("unitname");// EntityManager em = emf.createEntityManager();// EntityTransaction tx = em.getTransaction();// System.out.println("event Insert Start"); EntityTransaction tx = em.getTransaction(); tx.begin(); em.persist(event); tx.commit(); em.close(); 위 처럼 해당 Dao에서 엔티티매니저를 생성 해서 사용하면 커밋이 작동 하긴 합니다..
