Hi,

I run a jetpack container on Jetson AGX Xavier as link bellow.

When I import vpi in python 3.8 console I get the following error:
ImportError: libnvsocsys.so: cannot open shared object file: No such file or directory

What should I do to make vpi work in python?

Thank you in advance…

Hi,

Did you set up your environment with JetPack 5.0.2?
Since VPI 2.1 cannot work on the r34 BSP (DP).

Thanks.

Hi,

We don’t meet the same error on l4t-jetpack:r35.1.0 container.
Could you check it again?

Hi,

Based on your log, the device is set up with JetPack 4.6.3 which includes VPI 1.x.

VPI starts python support from VPI 2.x.
Please upgrade your device to JetPack 5.0.2 first.

Thanks.
