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 from .io.load import load_mesh, load_path, load, available_formats File "/usr/local/lib/python2.7/dist-packages/trimesh/io/load.py", line 14, in from .assimp import _assimp_loaders File "/usr/local/lib/python2.7/dist-packages/trimesh/io/assimp.py", line 130, in import pyassimp File "/usr/lib/python2.7/dist-packages/pyassimp/init.py", line 1, in from .core import * File "/usr/lib/python2.7/dist-packages/pyassimp/core.py", line 29, in class AssimpLib(object): File "/usr/lib/python2.7/dist-packages/pyassimp/core.py", line 33, in AssimpLib load, load_mem, release, dll = helper.search_library() ValueError: need more than 3 values to unpack

and get the errors when running "python collect_images.py": Traceback (most recent call last): File "collect_images.py", line 15, in from postprocess import postprocess File "/home/ys/multi-contact-grasping/src/postprocess.py", line 9, in from lib.utils import (format_htmatrix, invert_htmatrix, File "../lib/utils.py", line 5, in import trimesh File "/usr/local/lib/python2.7/dist-packages/trimesh/init.py", line 20, in from .io.load import load_mesh, load_path, load, available_formats File "/usr/local/lib/python2.7/dist-packages/trimesh/io/load.py", line 14, in from .assimp import _assimp_loaders File "/usr/local/lib/python2.7/dist-packages/trimesh/io/assimp.py", line 130, in import pyassimp File "/usr/lib/python2.7/dist-packages/pyassimp/init.py", line 1, in from .core import * File "/usr/lib/python2.7/dist-packages/pyassimp/core.py", line 29, in class AssimpLib(object): File "/usr/lib/python2.7/dist-packages/pyassimp/core.py", line 33, in AssimpLib load, load_mem, release, dll = helper.search_library() ValueError: need more than 3 values to unpack

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