When I run ‘nvidia-smi’ in terminal, it returns the error message as below:
-bash: nvidia-smi: command not found
However, when I run ./deviceQuery in /usr/local/cuda/samples/1_Utilities/deviceQuery , it can display my GPUs, as below:

When I run sample applications in Driveworks, there are no error messages as well and it seems the GPUs are working normally.
So, the question is： Why nvidia-smi is not avaiable on DrivePX2?, if it is a driver problem, why cuda can be running without issuing error messages?
Thanks very much and looking forward to any suggestions.
Best regards,
