Segfault in p.calculateJacobian()

Post by DanielSJohnson »

Hi everyone,

I'm having issues where my calls to p.calculateJacobian() result in a segmentation fault. The code to recreate this is:

Code: Select all

import pybullet as p
import numpy as np


robotId = p.loadURDF(robot_path, flags=p.URDF_USE_SELF_COLLISION, physicsClientId=phyID)

jacobian=p.calculateJacobian(robotId, 7, [0, 0, 0], np.zeros(18) ,np.zeros(18),np.zeros(18), physicsClientId=phyID)
This results in the terminal output:

Code: Select all

pybullet build time: May 20 2022 19:41:54
Segmentation fault (core dumped)
with no further information.

I am using pybullet version 3.17, python version 3.6.9 and im running the whole thing via a WSL install of Ubuntu 18.04.5 LTS.

Any assistance would be greatly appreciated!
