python - 带有 docker : __init__() got an unexpected keyword argument 'column' 的 Jupyter

Question

我最近使用 docker 安装了支持 GPU 的 TensorFlow:

docker pull tensorflow/tensorflow:latest-gpu-jupyter

但有时当我使用以下命令启动 jupyter notebook 服务器时:

docker run --gpus all -it -p 8888:8888 tensorflow/tensorflow:latest-gpu-jupyter jupyter notebook --notebook-dir=/tf --ip 0.0.0.0 --allow-root --NotebookApp.allow_origin='https://colab.research.google.com'

我在终端上看到以下异常:

[IPKernelApp] ERROR | Exception in message handler:

  File "/usr/local/lib/python3.6/dist-packages/ipykernel/kernelbase.py", line 272, in dispatch_shell

    project=Project(Path.cwd()), **kwds)
TypeError: __init__() got an unexpected keyword argument 'column'

之后，我必须重新启动服务器或从 google colab 重新连接。
错误可能来自哪里以及如何修复它的任何想法？

Answer 1

这个好像是jedi和ipython不兼容，见this issue .
修复方法是将 jedi 固定到 0.17.2，所以要么运行:

pip install jedi==0.17.2

或者，如果您使用的是诗歌，请将其添加到您的 pyproject.toml 中:

jedi = "<=0.17.2"

但是由于您使用的是 docker 镜像，因此需要更新该镜像。好像是gpu-jupyter.Dockerfile .
我会在那个项目上提出一个问题，看看他们是否可以固定 jedi就像他们对 nbformat 所做的那样，或者你可以 fork 它。他们也应该升级 python，3.6 有点长了。
