ModuleNotFoundError: No module named 'pxr'

Hello, when I run this command as described in the documentation (with a space between “kaolin/” and “tests”):

pytest --cov=kaolin/ tests I get the attached output. Any hints on what I am missing? other than: Hint: make sure your test modules/packages have valid Python names.

Thanks

Pablo

Prior to running the tests, please run the command source setenv.sh, which will point Python to the necessary libraries. This needs to be better documented, so thank you for bringing it up!

@vmlaker, we use a version of USD that has been adapted to Python 3.6+. You can check it out here https://developer.nvidia.com/usd#binaries. Note, USDView remains only compatible with Python 2.

Hi did you find a solution to it? In my case, after installing usd-core (latest version:22.3) through pip install, the error message does not appear .
