Segmentation fault (core dumped) when I am using clump in Tiaxial test

Hello,

I use Yadedaily on ubuntu 18 and 20. I want to simulate a triaxial test. When I use clump instead of spherical particles, I received this error:
Segmentation fault (core dumped)
I don't know how to fix it. I was wondering if you could help me. An example of my script is:

from yade import pack, qt

import sys
from numpy import *

qtr.bgColor=(1,1,1)
