USD Installation in Ubuntu

Hi NVIDIA,

I’m having issue with omni.isaac.DrSchema, which invokes an error as importing Usd module from pxr

I asked them here in this issue, however, the guy posting it built USD by CMake, but I installed it using the default script: sudo python3 build_scripts/build_usd.py /usr/local/USD

### Description of Issue Python cannot import any of the USD packages includi…ng `pxr.Usd`,` pxr.Tf`, etc. Here is what happens when I try.

Download and build glew, opensubdiv, ptex, and tbb from source, install to custom directories. 2. Install other dependencies using yum. 3. Configure and build USD using cmake, install to a custom directory. 4. Set PYTHONPATH and LD_LIBRARY_PATH to include ./install/USD/lib/python and ./install/USD/lib respectively. 5. Open a python2.7 interpreter 7. Type `import pxr.Usd` ### System Information (OS, Hardware) - centos7 - devtoolset-6 for compilers ### Package Versions - v19.11 - v19.07 - dev branch on Jan 15 2020 ### Build Flags BOOST_USE_STATIC_LIBS=true OpenGL_GL_PREFERENCE=GLVND PYSIDE_USE_PYSIDE2 = TRUE CMAKE_C_FLAGS and CMAKE_CXX_FLAGS = -fPIC Others setting the locations of all of the libraries built from source PYTHON_EXECUTABLE=/usr/bin/python2.7 PYTHON_INCLUDE_DIR=/usr/include/python2.7 PYTHON_LIBRARY = /usr/lib64/libpython2.7.so

So do you build USD using a specific installation CMake script or if you also installed using the default one, did you have issue with from pxr import Usd like this?

So I just found this link providing USD prebuilt version, let me try it then:
https://developer.nvidia.com/usd

Hi Tadinu,

Please keep in mind the USD in Isaac Sim (Omniverse) is a modified version of Pixar USD, many schemas have been added to it.

Kindly,
Liila

Hi @ltorabi Liila,

So I tried NVIDIA’s USD prebuilt one and it showed seemingly no difference or just similar import errors. But if I type the import directly into the Script Editor inside IsaacSim, it works.
Then I figured out that by running:

export ISAAC_SIM_PATH=~/ISAAC/ISAAC_SIM_2020_1/_build/linux-x86_64/release
source ${ISAAC_SIM_PATH}/setup_python_env.sh

I should not add the external USD python lib to PYTHONPATH anymore.

Thanks.

Great.
Thanks Tadinu.
