无法解决“错误：Git 服务器扩展不可用”。用于 Pytorch jupyter 笔记本

Question

创建新的笔记本实例（VM 类型：Pytorch 1.4）后，打开时出现与 Git 服务器扩展相关的内部错误：

Internal Error:

Fail to get the server root path. Error: Git server extension is unavailable. Please ensure you have installed the JupyterLab Git server extension by running: pip install --upgrade jupyterlab-git. To confirm that the server extension is installed, run: jupyter serverextension list.

这意味着我不能使用返回的 Git 克隆按钮：

Clone failed:

JSON.parse: unexpected character at line 1 column 1 of the JSON data

当我尝试命令时，jupyter serverextension list，我发现 git 扩展被禁用了。

 jupyterlab_git disabled
    - Validating...
      jupyterlab_git 0.10.1 OK

我按照建议尝试了“jupyter serverextension enable --py jupyterlab_git --sys-prefix”和“pip install --upgrade jupyterlab-git”，但这似乎没有解决任何问题。以下是我的笔记本实例设置（如果未指定，则为默认设置）：

Region: us-west1 (Oregon)

Zone: us-west1-a

Environment: PyTorch 1.4 (with Intel® MKL-DNN/MKL and CUDA 10.1)

Machine type: n1-standard-4 (4vCPUs, 15 GB RAM)

GPU type: NVIDIA Tesla T4

Number of GPUs: 1

✓ Install NVIDA GPU driver automatically for me

这是否发生在其他人身上？我看到了一篇关于 TensorFlow VM(Unable to resolve "Error: Git server extension is unavailable." (Google Notebooks)) 的类似帖子，想知道是不是同样的场景？

作为链接[1]，这是一个已知问题，并在新发布的图像（m47）[2]中得到解决：
