If you don't want the kernel to initialize the namespace
from the scope of the surrounding function,
and/or you want to load full IPython configuration,
you probably want `IPython.start_kernel()` instead.
Parameters
----------
module : types.ModuleType, optional
The module to load into IPython globals (default: caller)
local_ns : dict, optional
The namespace to load into IPython user namespace (default: caller)
kwargs : various, optional
Further keyword args are relayed to the IPKernelApp constructor,
allowing configuration of the Kernel. Will only have an effect
on the first embed_kernel call for a given process.

including loading startup files, configuration, etc.
much of which is skipped by `embed()`.
This is a public API method, and will survive implementation changes.
Parameters
----------
argv : list or None, optional
If unspecified or None, IPython will parse command-line options from sys.argv.
To prevent any command-line parsing, pass an empty list: `argv=[]`.
user_ns : dict, optional
specify this dictionary to initialize the IPython user namespace with particular values.
kwargs : various, optional
Any other kwargs will be passed to the Application constructor,
