vim-ipython in cygwin

[lucasfariaslf]

I'm trying to use vim-ipython under cygwin, IPython works outside vim, and I believe I have all necessary libs. I wonder if the error message could help you guys help me.

I first create and example .py: vim test.py. Once inside vim I call :IPython, which yields:

/usr/lib/python2.7/site-packages/IPython/config.py:13: ShimWarning: The `IPython.config` package has been deprecated since IPython 4.0. You should impo
rt from traitlets.config instead.

Sorry you're having trouble with vim-ipython. This sounds like a duplicate of #113.

Do you have an ipython kernel running? vim-ipython does not currently start a new kernel, it can only connect to kernels that have already been started via either ipython kernel or ipython console or by opening up a notebook file in jupyter.

Yeah, opening a jupiter console solved it. Thanks.
