     `start_ipython()` does full, regular IPython initialization,

     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
