如何在IPython / Jupyter笔记本中自动加载配置文件？

Question

In earlier versions of IPython it was possible to load a specific profile by

ipython notebook --profile=my_profile

so that I can include things like autoreload in my_profile.

Since using IPython 4.0.1 (Jupyter actually) I'm getting the

[W 09:21:32.868 NotebookApp] Unrecognized alias: '--profile=my_profile', it will probably have no effect.

warning, and the profile is not loaded. Have you come across a workaround?

Answer 1

In Jupyter create a kernel for each profile.

Find the kernels directory under the jupyter configuration directory {jupyter configuration}/kernels (on my Mac this is $HOME/Library/Jupyter/kernels ):

$ mkdir profile-x-kernel
$ cat << EOF > profile-x-kernel/kernel.json
{                                
    "display_name": "Profile X (Python 3)",
    "language": "python3",          
    "env": { },                              
    "argv": [ "python3", "-m", "ipykernel", "--profile", "profile_x", "-f", "{connection_file}" ]
}
EOF                          

Then you can select the kernel from the kernel menu in Jupyter, without having to restart the whole notebook server.
