v, vt, vn, f, ft, fn, mtl_path, landm, segm = loadobj(filename) ValueError: Could not load file

Successful installation，but show Could not load file, loadobj() function don't exist

(My opinion) I think the error says the mesh file was not found. I saw this when I tried it the first time. I had a typo in the file name. Check if that is the same for you.
