nvidia-smi command not found... I'm obviously missing something

Fresh user of the Jetson TX1 and I’ve been learning and working through examples, but I am obviously missing something basic that I haven’t found. How could my TX1 with the Jetpack installation not have the Nvidia drivers and the smi command?
‘nvidia@tegra-ubuntu:~$ nvidia-smi
nvidia-smi: command not found’

Hi,

  1. You don’t need to install driver separately. Flash image also install the driver.

  2. Nvidia-smi doesn’t support Tegra.

If you want to check GPU utilization, please use tegrastats

sudo ./tegrastats

If you want to check GPU memory, please use cudaMemGetInfo() function
