We are trying to build and execute some custom scripts in Isaac Sim. The environment is running on Ubuntu 20.04 in headless mode with --no-window and --allow-root options.
Executing the scripts in the integrated GUI editor works fine, but running them as suggested in the docs via the python.sh file does not. We are getting linker errors such as this one (absolute home path replaced by ~):
Traceback (most recent call last): File "~/test.py", line 2, in <module> from omni.usd.libs.pxr import Gf, Sdf, UsdPhysics File "~/.local/share/ov/pkg/isaac_sim-2021.1.1/kit/extscore/omni.usd/omni/usd/__init__.py", line 1, in <module> from ._impl import * File "~/.local/share/ov/pkg/isaac_sim-2021.1.1/kit/extscore/omni.usd/omni/usd/_impl/__init__.py", line 1, in <module> from .._usd import * ImportError: ~/.local/share/ov/pkg/isaac_sim-2021.1.1/kit/extscore/omni.usd.libs/bin/libgf.so: undefined symbol: _ZN32pxrInternal_v0_20__pxrReserved__11TfMallocTag10_doTaggingE There was an error running python
- Importing from pxr and omni.usd instead. The error message changes to another function, but persists in the same way.
- Adding all possible directories to LD_LIBRARY_PATH, such as the ones in
kit/extscore/omni.usd.libs/pxr, which contain compiled libraries. Does not resolve the issue.
- Executing and fidgeting with other scripts like the
python.shin the kit directory. Does not help either, and runs into additional errors.
- Sourcing the paths in the terminal and executing the regular python3 to run the script. Same issue persists.
Any ideas on what the problem is and why it works in the internal script editor?
