docker 的 Jupyter：init() 得到了一个意外的关键字参数 'column'

Question

我最近安装了支持 GPU 的 TensorFlow docker:

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。

知道错误的来源以及如何解决吗？

Answer 1

这似乎是 jedi 和 ipython 之间的不兼容，参见 this issue。

修复方法是将 jedi 固定到 0.17.2，因此运行:

pip install jedi==0.17.2

或者，如果您使用的是诗歌，请将此添加到您的 pyproject.toml:

jedi = "<=0.17.2"

但是由于您使用的是 docker 图片，因此需要更新该图片。好像是gpu-jupyter.Dockerfile.

我会针对该项目提出一个问题，看看他们是否可以像 nbformat 那样固定 jedi，或者您可以将其分叉。他们也应该升级 python，3.6 有点老了。

我会在@daphtdazz 的回答中添加更多细节。我必须执行以下步骤来解决此问题：

1。从 github:

下载 TensorFlow

git clone https://github.com/tensorflow/tensorflow.git

2。编辑文件 gpu-jupyter.Dockerfile，在第 104 行末尾添加 jedi==0.17.2：

vim tensorflow/tensorflow/tools/dockerfiles/dockerfiles/gpu-jupyter.Dockerfile

3。将自己放在 dockerfiles 文件夹中：

cd tensorflow/tensorflow/tools/dockerfiles/

4。构建图像：

docker build -f ./dockerfiles/gpu-jupyter.Dockerfile -t tf .
