Error executing Jupyter command                                                                  
 '/Users/charlesthomas/.emacs.d/elpa/ob-ipython-20180224.953/client.py': [Errno 2] No such file or directory                                                                                     

The version of emacs and ipython and ob-ipython is the newest on my mbp.
I install ob-ipython by MEPLA.
and the document of client.py just where it should be.

look at issue #162 .
I met the same problem, and solved it by using (setq python-shell-interpreter "ipython")
Maybe it can help.
