Kernel 使用ipcluster时指定自定义内核

我有一个定制的Jupyter内核。它是使用kernel.json kernelspec指定的

从kernel.json提取的内容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}

我想将这个内核与IPython并行使用。例如，使用其中几个自定义内核运行ipcluster

我已经创建了一个新的IPython配置文件

（ipython 5.1.0版）

这将创建一个包含各种配置（.py）文件的概要文件文件夹

我可以用个人资料运行ipython

ipython --profile gdb_gcc_par --debug

输出：

如果我在ipython_config.py中引入了一个错误，我会看到一条错误消息，因此我得出结论，该配置文件已被考虑在内

如果我在ipython_kernel_config.py中引入一个错误，我看不到任何更改，因此我得出结论，这个配置文件没有被考虑进去

如何指定要使用的内核

我发现这个网站：

其中包括以下代码段：

c = get_config()
c.KernelManager.kernel_cmd = ["/path/to/executable/kernel_exe",
                              "{connection_file}"]  

我将该代码段添加到ipython_config.py中。然而，这没有效果

此外，我发现kernel_cmd已被弃用

我试过一些东西：

尝试1（无效）

尝试2（无效）：

添加到~/.ipython/profile\u gdb\u gcc\u par/ipython\u config.py

c.KernelManager.kernel_cmd=['python', 'simple_kernel.py', '{connection_file}']

跑

没有效果

c = get_config()
c.KernelManager.kernel_cmd = ["/path/to/executable/kernel_exe",
                              "{connection_file}"]  

ipcluster start --n=4 --KernelManager.kernel_cmd="['python', 'simple_kernel.py', '{con
nection_file}']"

c.KernelManager.kernel_cmd=['python', 'simple_kernel.py', '{connection_file}']

ipython --profile gdb_gcc_par
