Describe the issue

I am using open3d to show car 3d model in my code, when i use the python script to load .obj file, hubs for the car is missing, other car parts is ok; but when i open the obj file using open3d.exe, the hubs is ok, and the whole car shows perfect, what is the difference between python script and open3d.exe obj display window for exe and python script: obj_load_error my model data: obj_data.zip

Steps to reproduce the bug

import open3d as o3d

def visualize(mesh):
    vis = o3d.visualization.Visualizer()
    vis.create_window()
    vis.add_geometry(mesh)
    vis.run()
    vis.destroy_window()

mesh = o3d.io.read_triangle_mesh('./material.obj',True)
mesh.compute_vertex_normals()
visualize(mesh) # or o3d.visualization.draw([mesh])

Error message

[Open3D WARNING] [ViewControl] SetViewPoint() failed because window height and width are not set.

Expected behavior

hubs should show normally as exe when load obj file using python script
