helloworld_panda.py is not working - robot model is not loading

[janisa9]

I followed the provided installation instructions, but helloworld_panda.py is not working

It seems that it cannot load the robot model and crashes after ~30sec,

(ve_pybullet) janis@janis-MS-7B86:~/pybullet-robot-envs$ python3 pybullet_robot_envs/examples/helloworlds/helloworld_panda.py /home/janis/pybullet-robot-envs/pybullet_robot_envs/examples/helloworlds pybullet build time: Apr 21 2020 23:16:24 current_dir=/home/janis/pybullet-robot-envs/pybullet_robot_envs/envs/panda_envs startThreads creating 1 threads. starting thread 0 started thread 0 argc=2 argv[0] = --unused argv[1] = --start_demo_name=Physics Server ExampleBrowserThreadFunc started X11 functions dynamically loaded using dlopen/dlsym OK!

Thus the test_panda_push_gym_env.py also doesn't load the model of the robot etc.

I suppose there is something wrong with my installation, but I cannot figure out what exactly.

I am sorry for the issue, I believe the problem is related to git-lfs that needs to be installed before cloning the repository, otherwise it mess-up the mesh files. Basically, the git lfs pull is not working properly in this case. I will try to figure out the problem. So, please try to:

• First check your installation of git-lfs by following the instruction here. You need to download and install the package, then run git lsf install.
  • Then, clone again the pybullet-robot-envs repository. The meshes are automatically downloaded.

Thank you, I will take a look on that, I suppose I missed something with git lsf

That was the case, thank you!
