Trouble Shooting#

GPU memory problems with IsaacLab#

If you interrupt the process, the GPU memory may not be released because the forked process is not killed. You need to manually kill it by running:

pkill -9 pt_main_thread

No Space XXX#

  • If you meet Failed to create change watch for ... No space left on device, it doesn’t really matter. You can simply ignore it, or change your system setting by running echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf or just simply restart the system.

libGLU problem#

  • If you are running on a server in headless mode, and meet Failed to open /.../iray/libneuray.so: libGLU.so.1: cannot open shared object file: No such file or directory, try:

    sudo apt-get update
sudo apt-get install libglu1-mesa

USD Missing#

  • If you load a USD to the scene but is invisible, It might be that the USD path is not correctly set. The safest way is to use absolute path, and to make the code clean, please use the os.path.abspath to convert the relative path to absolute path. For example:

usd_path=os.path.abspath(f"data_isaaclab/robots/FrankaEmika/panda_instanceable.usd"),
