我有一个自定义的Jupyter内核。它使用kernel.json kernelspec。
指定kernel.json的摘录显示了如何启动自定义内核：
source /opt/conda/bin/activate gdb_ipykernel && exec /opt/conda/envs/gdb_ipykernel/bin/python -m gdb_test.do_tests gdb_test._ipykernel -f {connection_file}
我想将此内核与IPython并行使用。例如，使用其中几个自定义内核运行ipcluster。
我创建了一个新的IPython配置文件
（ipython版本5.1.0）
ipython profile create --parallel --profile=gdb_gcc_par
这将创建一个包含各种配置（.py）文件的配置文件文件夹。
db ipcluster_config.py ipengine_config.py ipython_config.py log security
history.sqlite ipcontroller_config.py ipython_config_old.py ipython_kernel_config.py pid startup
我可以使用个人资料运行ipython
ipython --profile gdb_gcc_par --debug
输出：
(root) dinne@654f3bb1ef03:~/.ipython/profile_gdb_gcc_par$ ipython --profile gdb_gcc_par --debug

如果我在ipython_config.py中引入错误，我会看到一条错误消息，因此我认为此配置文件已被考虑在内。
如果我在ipython_kernel_config.py中引入错误，我没有看到任何更改，所以我得出结论，此配置文件不被考虑在内？
如何指定要使用的内核？
我找到了这个网站：
http://andrew.gibiansky.com/blog/ipython/ipython-kernels/
包含此代码段：
c = get_config()
c.KernelManager.kernel_cmd = ["/path/to/executable/kernel_exe",
"{connection_file}"]
我将代码段添加到ipython_config.py。但是这没有效果。
此外，我发现不推荐使用kernel_cmd
我尝试过的一些事情：
尝试1（无效）
ipcluster start --n=4 --KernelManager.kernel_cmd="['python', 'simple_kernel.py', '{con
nection_file}']"
尝试2（无效果）：
添加到〜/ .ipython / profile_gdb_gcc_par / ipython_config.py
c.KernelManager.kernel_cmd=['python', 'simple_kernel.py', '{connection_file}']
运行
ipython --profile gdb_gcc_par
没效果。
