请通过卸载和重新安装帮助尝试了很多，但这不起作用。

解决方案

  1. 你应该找到文件jupyter_config.json，它的路径可能像这样 'C:\Users\mi.conda\envs\pytorch_1.7_cpu\etc\jupyter' 然后，删除

     "kernel_spec_manager_class": "nb_conda_kernels.CondaKernelSpecManager"

    remove 删除它，包括上面存在的逗号。

  2. 删除了以下三个文件夹（尽管您可能需要进行一些备份...）

    ~/.jupyter

    ~/.ipython

    ~/.local/share/jupyter

（这里我删除了除“kernels”子文件夹之外的所有内容）

  1. 我运行了以下 4 条指令：

    jupyter nbextension install --user --py widgetsnbextension

    jupyter nbextension install --user --py bqplot

    jupyter nbextension 启用 --user --py widgetsnbextension

    jupyter nbextension 启用 --user --py bqplot
