if min_range <= disparity[row, column] <= max_range: IndexError: index 230 is out of bounds for axis 0 with size 230

[Rishi5583]

When running the master.py , I am getting errors :
rd.convert_to_ply(disparity=disparity,model_3d=model3D_matrix ,name=name, image_path=path_r, cmp_range=70,percent=15, downsample_n=0)
File "C:\src\RealDepth.py", line 136, in convert_to_ply
if min_range <= disparity[row, column] <= max_range:
IndexError: index 230 is out of bounds for axis 0 with size 230
I have changed index value , nothing working fine . Please help & guide me , it will be very helpful for me .
Regards.
Btw , I am using Python 3.7.
