I wrote a custom completer for h5py some years ago, and discovered a
problem after updating ipython to the latest version:

[TerminalIPythonApp] WARNING | Error in loading extension:
h5py.ipy_completer Check your config files in
/home/darren/.ipython/profile_default Traceback (most recent call last):
File "/opt/conda/lib/python2.7/site-packages/IPython/core/shellapp.py",
line 267, in init_extensions

"/opt/conda/lib/python2.7/site-packages/h5py/ipy_completer.py", line 59, in
<module> from IPython import generics ImportError: cannot import name

I'm sorry if this has an obvious solution that has been announced
somewhere, maybe I don't know where to look anymore. Is there a list of
changes that has been made to the API? What happened to generics?
