안녕하세요!
혹시 finance-datareader==0.9.1 로 같은 버전의 라이브러리를 설치를 하셨을까요?
jupyter노트북을 완전히 종료하고, anaconda prompt에서 pip install finance-datareader==0.9.1 실행 후 jupyter 재실행해서 확인해보시겠어요?

교수님께서 앞 강의에서 !pip install -r requirements.txt를 통해 모든 library를 한꺼번에 설치하는 방법을 가르쳐주셔서 여기를 통해 다시 해봤는데, 아래와 같이 뜹니다. 판다스를 다시 깔아야 하는 건가요?

교수님 신속한 답변 감사드립니다. 말씀대로 anaconda prompt에서 pip install finance-datareader==0.9.1 실행 후 jupyter 재실행해 봤는데, 아래와 같이 됩니다. 무엇이 문제일까요..ㅠ
