Pyenv 가상 환경에서 Jupyter 노트북 서버에 연결할 수 없습니다(오류 404).

운영 체제: 5.14.14-arch1-1 GNU/Linux x86_64
패키징 : jupyter4.6.3, 6.4.4, jupyter-notebook2.2.0]pyenv

내 설정은 필요한 모든 패키지와 Python 모듈이 사전 설치된 pyenv디렉터리의 가상 환경에서 jupyter를 시작하고 /path/to/my_directory해당 특정 환경에 대한 사용자 정의 iPython 커널을 구축하는 것으로 구성됩니다. 노트북 세션에서 사용자 정의 iPython 커널을 사용할 수 있게 만드는 것은 다음과 같습니다.

$ cd /path/to/my_directory
$ pyenv local 3.7.0
$ python -m pip install -r <requirements_file>
$ ipython kernel install --user --name <my_kernel> --display-name "Python3.7.0 (<my_kernel>)"
$ jupyter notebook

...그런 다음 Jupyter 콘솔 메뉴에서 "파일 > 새 노트북"을 선택한 다음 새 노트북 브라우저 창에서 "my_kernel"을 선택합니다. 이 방법은 오늘날까지 완벽하게 작동했습니다.

어제 모든 것이 잘 작동하여 사용자 정의 커널을 부팅했습니다. 오늘은 다른 날입니다. 변경 사항은 기본적으로 빌드와 관련된 몇 가지 사소한 업데이트를 포함하는 일부 패키지 업그레이드입니다.

연결 실패
노트북 서버에 연결할 수 없습니다. 노트북은 계속해서 다시 연결을 시도합니다. 네트워크 연결이나 노트북 서버 구성을 확인하세요.

  • Python 3.7.0 심을 다시 설치하세요.
    $ pyenv rehash

  • 3.7.0 virt-env에서 필요한 3GB 패키지를 다시 설치하기 시작했습니다 ipykernel. 결과는 Segmentation fault (core dumped).

    $ cd /path/to/my_directory

아직 이 문제를 해결하기 위해 노력하고 있습니다. 어떤 제안이라도 환영합니다.
