Hi,
‘GR3D_PCI’ is always ‘% 0%’ no matter which sample I run when I use tegrastatus command to monitor dGPU usage even I use ‘export CUDA_VISIBLE_DEVICES=0’. Is something wrong?
Information when I run sample_drivenet_multigpu is as follows.
nvidia@nvidia:/usr/local/driveworks/bin$ ./sample_drivenet_multigpu
