Hi @MotivaCG !

Did you previously get this warning? https://github.com/NVIDIAGameWorks/kaolin/blob/master/kaolin/io/usd.py#L32

[MotivaCG]

Nope it didn't trigger that warning you can check it on your own https://colab.research.google.com/drive/1m4jRzuQY2sSpjaS2i-pUgKuMsCf16vRU?usp=sharing

Can you try from pxr import Usd? This is weird because I do see that usd-core is getting installed during kaolin installation.
