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

운영체제: 5.14.14-arch1-1 GNU/Linux x86_64
패키지: jupyter4.6.3, jupyter-notebook6.4.4, pyenv2.2.0]

내 설정은 필요한 모든 패키지와 Python 모듈이 사전 설치된 pyenv디렉토리의 가상 환경 에서 jupyter를 시작하고 해당 특정 환경에 대한 사용자 정의 iPython 커널을 구축하는 것으로 구성됩니다 . /path/to/my_directory노트북 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 선택하고 새 노트북 브라우저 창에서 "my_kernel"을 선택합니다. 이 방법은 오늘날까지 완벽하게 작동했습니다.

어제 모든 것이 제대로 작동하여 포함된 사용자 정의 커널을 시작했습니다. 오늘은 다른 날입니다. 변경 사항은 기본적으로 몇 가지 패키지 업그레이드였으며 그 중에는 빌드와 관련된 여러 가지 사소한 업데이트도 있었습니다.

  • pyenv, jupyter및 jupyter-nbconvert, 하나씩 순서대로 롤백되었습니다 . 예를 들어:
    $ sudo pacman -U jupyter-nbconvert-6.1.0-1-any.pkg.tar.zst

  • 매번 재부팅 -> 변경 없음

  • 3.7.0용 Python 가상 환경 바이너리를 다시 설치했습니다.
    $ pyenv uninstall 3.7.0
    $ pyenv install 3.7.0

  • Python 3.7.0 shim을 다시 설치했습니다.
    $ pyenv rehash

  • 3.7.0 virt-env에 3GB의 필수 패키지를 다시 설치하기 시작했습니다 ipykernel. 결과는 입니다 Segmentation fault (core dumped).

    $ cd /path/to/my_directory
$ pyenv local 3.7.0
$ python -m pip install ipykernel
Segmentation fault (core dumped)
$ python -m pip install -U pip
Segmentation fault (core dumped)
$ ... etc...

아직 문제를 해결하고 있습니다. 어떤 제안이라도 환영합니다.
