get_ipython returns None when called from startup file

See original GitHub issue

I’m following the instructions given here. Nevertheless, and despite https://github.com/ipython/ipython/issues/9791 and https://github.com/ipython/ipython/pull/9818:

i. get_ipython is not exposed as a builtin. ii. Even when imported as described in the documentation, get_ipython() returns None.

The startup file is just profile_default/ipython_config.py.

I’m testing this agaist the latest revision:

ipython --version
6.2.0.dev

The startup file is just profile_default/ipython_config.py.

That’s not a startup file! See the section Startup files here:

@memeplex do you have any sample code. I am facing the same problem, but couldn’t able to get your conversation about reading the config file @takluyver

def initialize(self):
    if ipy.get_ipython() is None:
        self._create_profile() #  passing command to subprocess to create a profile
    print(f'ipython profile: {ipy.get_ipython()}') # still I am getting None

⋊> ~/c/i/i/ipycli on master ⨯ ipython profile create
[ProfileCreate] Generating default config file: '/Users/xyz/.ipython/profile_default/ipython_config.py'
[ProfileCreate] Generating default config file: '/Users/xyz/.ipython/profile_default/ipython_kernel_config.py'

do I need to change any config under ipython_config.py, my objective is to define_macro in ipython
