Undefined symbol: _ZTV22OdAbstractDeserializer in isaac sim 4.2

Omniverse Isaac Sim

Hi all, I just got ISAAC sim 4.2.
When I try to import from a CAD file, I bump into this error :

“/media/*/12dae5b9-af3b-42e8-8d60-dae2b57f4a49/isaac/Kit/Isaac-Sim/4.2/exts/3/omni.kit.converter.hoops_core-500.0.21+106.0.1.lx64.r.cp310/bin/libOdConstraints.so: undefined symbol: _ZTV22OdAbstractDeserializer”

Thanks

Is this error reproducible only with specific CAD files, or does it occur with all CAD imports? If possible, try importing different CAD files to see if the issue persists.

Have you attempted to restart your computer and try the import again? Or reinstall Isaac Sim?

Hi @stefano.mutti

Isaac Sim 4.2 is implemented on top of Kit 106.1.0 so the correct extension version should be omni.kit.converter.hoops_core-500.0.17+106.1.0.lx64.r.cp310

“/media/*/12dae5b9-af3b-42e8-8d60-dae2b57f4a49/isaac/Kit/Isaac-Sim/4.2/exts/3/omni.kit.converter.hoops_core-500.0.21+106.0.1.lx64.r.cp310/bin/libOdConstraints.so: undefined symbol: _ZTV22OdAbstractDeserializer”

Try deleting the chache folder Kit in the path you have it

Hi @stefano.mutti

Try running Isaac Sim form terminal with the next CLI arguments: --clear-cache --clear-data --reset-user

I still have the same error with the additional args, even after I completely cleared the issac folders and installed it anew.
Thanks
