VSS on DGX Spark - ImportError: libnvrm_mem.so

Hi everyone,

I’m trying to deploy VSS on my DGX Spark, following the guide available here: NVIDIA DGX Spark — Video Search and Summarization Agent

After running all commands in the Fully local Single GPU docker deployment guide, the docker compose up never reaches the final stage of “VIA Server loaded”: a couple seconds after “Starting VIA server in release mode”, I see the “ImportError: libnvrm_mem.so: cannot open shared object file: No such file or directory”, and shortly after, the last via-server log entry: “ProcessGroupNCCL.cpp:1538] Warning: WARNING: destroy_process_group() was not called before program exit, which can leak resources”

How can I install the set of libnvrm libraries?

This issue got resolved by adding

export IS_SBSA=1

to the .env file.

Subsequently, I receive the following exception:
