I was getting a value error from GridSpec when the data had no planets, saying that ncols could not be 0. Fix that I used:
plot_multipanel in orbit_plots.py
Line 454 gs_phase = gridspec.GridSpec(self.phase_nrows, self.phase_ncols)
change to
Line 454 gs_phase = gridspec.GridSpec(max([1,self.phase_nrows]), max([1,self.phase_ncols]))
