'nb_conda_kernels.CondaKernelSpe

[C 13:39:16.979 NotebookApp] Bad config encountered during initialization:

[C 13:39:16.979 NotebookApp] The 'kernel_spec_manager_class' trait of <notebook.notebookapp.NotebookApp object at 0x0000016189936748> instance must be a type, but 'nb_conda_kernels.CondaKernelSpecManager' could not be imported

报错图片

因为之前一直使用jupyter（python3）作为算法模型开发的ide，最近在使用pycharm调试项目代码，项目代码python2的开发环境，所以想尝试使用anaconda同步项目代码的开发环境。

................忘了采取了什么操作导致上图报错内容出现，花费了大半天时间，才找到解决该问题的方法，做个记录。

1.-----------------------------------------------

In terminal, find the configurations directories withjupyter --paths.

In one of the directories there I found jupyter_notebook_config.json

Save a back up copy ;)

From the file delete the following line:

"kernel_spec_manager_class": "nb_conda_kernels.CondaKernelSpecManager"

5.Delete the comma preceding it. (Then...it may really works!)

找到你本地的anaconda安装路径:

./etc/jupyter/jupyter_notebook_config.json

删除：

"kernel_spec_manager_class": "nb_conda_kernels.CondaKernelSpecManager"

再次启动：jupyter notebook

over

2.----------------------------------------------------

经过1操作后，有可能你通过jupyter打开项目代码出现下图：

采用如下方法：

使用conda/pip将tornado版本降为  4.5.3
