Segmentation fault (core dumped)

Any clue that I got Segmentation fault (coredumped) when excuting
python vectorize_u3d.py logs/pretrained-wireframe/npz/003576000 --vpdir logs/pretrained-vanishing-points/npz/000096000 57
output:

Without extra information, it is hard to determine the cause. I suspect the problem is on the OpenGL/vispy side. If you are able to do some debugging, you can try to find the line number of the crash point.

vps = vanish_point_refine(np.array(junctions), np.array(lines), 
# vps = vanish_point_clustering2(np.array(junctions), lines)
K = estimate_intrinsic_from_vp(vps[0][0], vps[1][0], vps[2][0])[0]
invK = LA.inv(K)
print("K:", 1 / invK[0, 0])
depth = lifting_from_vp(vps, invK, junctions, -juncdepth, junctypes, lines)
vertices, projection_matrix = to_world(junctions, depth, lines, K)
#show_wireframe(
#    f"{npzdir}/wireframe/{index:06}", vertices, lines, projection_matrix
#)

I saw the picture after I comment the last 3 lines in vectorize_u3d.py. 13 pictures show up one after I close another.
I will try to debug deeper

It stoped here
85 def __init__(self, prefix, vertices, lines, proj_matrix, view_matrix): ->86 app.Canvas.__init__(self, config=dict(samples=8), size=(1024, 1024))

in wireframe>viewer.py>Cavas>init

and no more message

Ok, my fault.OpenGL is not installed well.
