Process sim_grasp.py terminates after loading all the scene

[MarioCavero]

I am have been trying to fix this issue where I run sim_grasp.py:
python3 scripts/sim_grasp.py --model data/runs/22-08-10-08-09_dataset\=foo\,augment\=False\,net\=conv\,batch_size\=32\,lr\=3e-04/vgn_conv_7.pt --sim-gui --rviz

Before, I run roscore in another console. All the previous instructions for the rest of the parts have been made. Also trained a model.

With the following output:

I have been trying to see if there was anything wrong with my ros installation. My system is Ubuntu 20.04 (Ubuntu 20.04.5 LTS). I am trying the simulation in VirtualBox, having done the previous parts on a real Ubuntu machine. Might it be something related to the VM?

Where is the error ? It is completed 100 % successfully

[MarioCavero]

I have followed all the steps, data generation and training. What appears as the simulation is I think the default, a box with objects dropping on it, on each "epoch" until 100%. No grasping nor my objects spawning. - 30 Sept 2022

EDIT 25 January 2023: Any insight on this @aniketghodake10

Hi, I also try to synthetic grasping trials in pile scene by using python scripts/generate_data_parallel.py --scene pile --object-set pile/train --num-grasps 400 --num-proc 2 --save-scene ./data/pile/data_pile_train_random_raw_4M, but the terminal show nothing but "pybullet build time: May 28 2020 16:37:34", the file in the data generation is nothing.
I want to ask , is there a problem? How to locate the bug and debug? @MarioCavero @aniketghodake10
Thanks!

[MarioCavero]

It's been 2 years almost so I cannot really say anything right now. I will re-check this repository in the following weeks so hopefully I'll be able to help out @Andyyoung0507

Thanks for your help!
