尝试启动 Jupyter 服务器时出现 sys.excepthook AssertionError

Question

在虚拟机（Linux Ubuntu 22.10、Python 3.10.7）上安装 pip 后，运行

jupyter

会出现错误jupyter notebook

我已经尝试过做

  File "/home/username/.local/bin/jupyter-notebook", line 5, in <module>
    from notebook.app import main
  File "/home/username/.local/lib/python3.10/site-packages/notebook/app.py", line 17, in <module>
    from jupyter_server.serverapp import flags
  File "/home/username/.local/lib/python3.10/site-packages/jupyter_server/serverapp.py", line 114, in <module>
    from jupyter_server.services.contents.filemanager import (
  File "/home/username/.local/lib/python3.10/site-packages/jupyter_server/services/contents/filemanager.py", line 23, in <module>
    from anyio.to_thread import run_sync
  File "/home/username/.local/lib/python3.10/site-packages/anyio/__init__.py", line 27, in <module>
    from ._core._sockets import connect_tcp as connect_tcp
  File "/home/username/.local/lib/python3.10/site-packages/anyio/_core/_sockets.py", line 35, in <module>
    from exceptiongroup import ExceptionGroup
  File "/home/username/.local/lib/python3.10/site-packages/exceptiongroup/__init__.py", line 20, in <module>
    from ._formatting import (
  File "/home/username/.local/lib/python3.10/site-packages/exceptiongroup/_formatting.py", line 394, in <module>
    assert sys.excepthook is apport_python_hook.apport_excepthook
AssertionError

如

here

所述，但这不会改变输出。我该如何解决这个问题？

Answer 1

我怀疑这与 Jupyter 对 IPython 的依赖有关，因为当我尝试运行“ipython --pylab”时，我得到了完全相同的错误。

我找到的唯一“解决方案”是进入“_formatting.py”文件并注释掉第 394 行的“assert sys.excepthook is apport_python_hook.apport_excepthook”。保存后，我可以启动交互式 shell在 IPython 中，我可以运行 Jupyter。

我想强调，这不太理想，我强烈建议不要这样做，但它可能会帮助您/其他人排除故障。
