Install cuDNN etc. on Jetson TX2 flashed with SDK Manager in Docker

[pyotr777]

After a few tries and errors, I could install Jetpack 4.5.1 on TX2 using the SDK Manager Docker image (Docker Images :: NVIDIA SDK Manager Documentation).
I have Ubuntu 20.04 installed on my PC, thus I had to use Docker.

However, I found that CUDA, cuDNN, OpenCV etc. were not installed.
Here is the output of the jetsonInfo script (GitHub - jetsonhacks/jetsonUtilities: Get information about the NVIDIA Jetson OS environment. Lists L4T and JetPack versions, along with major libraries.)

NVIDIA Jetson TX2
 L4T 32.5.1 [ JetPack 4.5.1 ]
   Ubuntu 18.04.5 LTS
   Kernel Version: 4.9.201-tegra
 CUDA NOT_INSTALLED
   CUDA Architecture: 6.2
 OpenCV version: NOT_INSTALLED
   OpenCV Cuda: NO
 CUDNN: NOT_INSTALLED
 TensorRT: NOT_INSTALLED
 Vision Works: NOT_INSTALLED
 VPI: NOT_INSTALLED
 Vulcan: 1.2.70

I could install CUDA with $ apt install cuda-tools-10-2.

However, OpenCV build fails.
How do I install OpenCV, cuDNN, TensorRT etc?

Hi,

When flashing TX2 with SDKManger, you can also install the components at the same time.
Or you can try the below command afterward:

$ sudo apt update
$ sudo apt install nvidia-jetpack

Thanks.

@AastaLLL That worked. Thank you!
