Is ${HOME}/NVIDIA-INSTALLER Not In L4T R19.3? Or Is It Deprecated?

Just did my flash of L4T R19.3 on Jetson. Did the script prior to this. The README.txt still refers to ${HOME}/NVIDIA-INSTALLER:

Need to know if this is an error that this one-time installer is not present, or if this is correct. I had expected it to be in the L4T so I did not back this up prior to flashing. Do we need this?

I just (re)flashed L4T R19.3. It did not include the NVIDIA_INSTALLER afterwards.

However, I was able to get up and running by installing CUDA and building the samples as documented here:

Now, I can run the samples and they all work.

linuxdev, NVIDIA-INSTALLER is not needed anymore. is enough.
I think NVIDIA-INSTALLER was for the factory build that comes with a new kit.
I guess, when you use one of the releases, it is not required anymore.

OK, but why does it not detect the 192 cuda cores?
