I want to know where can I find "Download object meshes as either the Wavefront .obj file format, or .stl file format, and place them in data/meshes/object_files"

In your prepare_mesh code, you use density 1000 instead of inbuilt value 1. Was wondering how do you determine the density value for the mesh?

Hi, I got this error when doing the first step (python prepare_mesh.py):

Error:

Traceback (most recent call last):
File "prepare_mesh.py", line 104, in
main(config_object_dir, config_mesh_dir)
File "prepare_mesh.py", line 87, in main
processed = process_mesh(mesh_path, mesh_output_dir)
File "prepare_mesh.py", line 46, in process_mesh
mesh_properties = mesh.mass_properties()
TypeError: 'dict' object is not callable

I'm not sure what wrong here. Any suggestion?
Thanks!

Dear mveres01,
I have some questions when reading and executing your code.
during step1, you said

$: cd initialize
$: python prepare_meshes.py

Maybe it's mean

$: cd initialize
$: python prepare_mesh.py

because there is no prepare_meshes.py in your repository but prepare_mesh.py.

And another question: I don't understand the meaning of follow sentence:

Run initialize/prepare_candidates.py. This will read the pose information collected by V-REP, and generate a list of candidates for each object that will be tested in the simulator. Note that these candidates will be saved under collect/candidates

$: cd initialize
$: cat ../data/initial_poses.txt | parallel python prepare_meshes.py

Does it's meaning we should run the following code

$: cd initialize 
$: python prepare_candidates.py
$: cat ../data/initial_poses.txt | parallel python prepare_meshes.py

Can you give me some tips? Thanks a lot!

Dear mveres01, when I run

cat commands/main1.txt |parallel -j 16

get the error message as following:

/bin/bash: vrep.sh: command not found

And if I replace the code in main0.txt:

ulimit -n 4096; export DISPLAY=:1; vrep.sh -h -q -s -g40_carafe_final-11-Mar-2016-17-09-17.txt -g1 -g1501 /home/forrest/robo/grasping/collect/scene_collect_grasps.ttt 

with

ulimit -n 4096; export DISPLAY=:1; /home/forrest/robo/V-REP_PRO_EDU_V3_4_0_Linux/vrep.sh -q -s -g40_carafe_final-11-Mar-2016-17-09-17.txt -g1 -g1501 /home/forrest/robo/grasping/collect/scene_collect_grasps.ttt

i.e.,I set the absolute path of vrep. But I just get another error:

QXcbConnection: Could not connect to display :1
/home/forrest/robo/V-REP_PRO_EDU_V3_4_0_Linux/vrep.sh: line 33: 15247 Aborted                 (core dumped) "$dirname/$appname" "${PARAMETERS[@]}"

And I have read the Trouble running V-REP headless in V-REP forum, but don't know how to deal with it.
Could you give me some suggestion about this problem? thanks!
