Solution: The jedi-vim pop-up display is broken

phenomenon

With jedi-vim inserted in NeoBundle, the pop-up display that suggests the arguments of the python function etc. is not displayed normally as shown in the image below.

It is displayed as `` = = jedi = 0, = = (* _ * seconds * _ *) = = jedi = appropriately, but please display it correctly as follows.
