plotting phase tensor residuals

[fsevim]

Dear all;

I get an error like below when i try to plot phase tensor residuals both as pseudo section and map.

TypeError: _read_ellipse_dict() missing 1 required positional argument: 'ellipse_dict'
I posted my script below.

import mtpy.imaging.mtplot as mtplot
import os
edipath1 = r"/home/user/mtpy/data/edifiles1"
edilist1 = [os.path.join(edipath1,edi) for edi in os.listdir(edipath1)
if edi.find('.edi')>0]
edipath2 = r"/home/user/mtpy/data/edifiles2"
edilist2 = [os.path.join(edipath2,edi) for edi in os.listdir(edipath2)
if edi.find('.edi')>0]
ptmap = mtplot.plot_residual_pt_maps(edilist1, edilist2,ellipse_dict={'size':1, 'cmap': 'mt_yl2rd',
'colorby': 'geometric_mean','range':(0,5)})
