jupyter notebook ImportError: cannot import name 'Type'

 

 

 

안녕하세요 봉자씨입니다.

 

파이썬3에서 주피터 노트북을 설치하면서 에러가 발생하는 부분이 있어서 혹시나 해서 공유드립니다.

아래와 같이 설치를 시도 했습니다.

bongjacy:~ bongdary$ pip3 install jupyter

 

문제 없이 설치 되는 듯합니다.

그런데 실행을 하니 실행이 안되고 아래와 같은 에러가 표시가 됩니다.

 

명령어를 실행합니다.

bongjacy:~ bongdary$ jupyter notebook

 

에러가 발생했습니다.

Traceback (most recent call last):

ImportError: cannot import name 'Type'

 

무슨 에러인지 확인을 이것 저것해봤습니다.

 

it's because of the version of tornado and python 3.

 

결국 tornado 이것을 어떻게 하면 해결이 난다는 것입니다.

그래서 아래와 같이 처리를 하니 잘 실행이됩니다.

 

pip install tornado==5.1.1

 

위와 같이 실행 후의 결과입니다.

bongjacy:~ bongdary$ jupyter notebook
