raise TypeError("Invalid comparison of non-real %s" % me) in sympy

I am getting this sympy related comparison error. Do you know how I can fix it? It doesn't seem that authors in the original repo are facing it. I see that for one of the pkl files, namely 001.pkl, the y2d is imaginary (not sure why), and is equal to 1.05147176800692e-6 + 3.72470439655723*I.

I am running this code: https://github.com/DirtyHarryLYL/DJ-RN/blob/master/script/generate_3D_obj_GT.py
