Errors when running the scripts

[yangshuo11]

Many thanks! According to your suggestion, I try it and find it works out. Here is what I do to solve this problem:
Open the shell commend, and input:
git clone https://github.com/mveres01/multi-contact-grasping
cd multi-contact-grasping
git checkout dev

Then I run the script src/collect_grasps.py. it works out correctly.

Thanks a lot. I will do grasp research based on it and make some progression in the future.

Hello, I am using Ubuntu 16.04 + ROS kinetic, V-REP-3.6.1.
After installing trimesh-2.29.10, and cope relevant files from V-REP/programming to /lib. I encountered the following errors when running "python collect_grasps.py":
Traceback (most recent call last):
File "collect_grasps.py", line 6, in
import trimesh
File "/usr/local/lib/python2.7/dist-packages/trimesh/init.py", line 20, in

and get the errors when running "python collect_images.py":

I have tried both the master and dev branches, but the errors remain the same. Could anyone give a clue? Many thanks!
