Cuda is not installed on jetson nano tx2 kit

I have purchased TX2 development kit few days back. The pre-default Linux is already installed on the system.

I am not able to find the cuda cudnn path and opencv path in the library. could you please help me on this?

As it is a fresh one. I would suggest you use nvidia sdk manager to upgrade your devkit first to 4.4.

Since jetpack 4.3 you may also do it via apt directly. (See Docs)

Inside those apt repos (or via sdkmanager) you may then install cuda or any other utils you desire.
You can also just install cuda and opencv to your target by just copying the jetpack 4.3 debs to your system. (Choose 4.3 in sdkmanager and skip flash or select download only).

See the above docs how to proceed.

Check if you have the nvidia repos enabled in your apt sources. Then after checking or enabling call sudo apt-get update to fetch the current package lists.

With apt-cache madison nvidia-jetpack you’ll get an nice overview of which versions are available and from where they will get pulled. As a cli-ui version for apt I can recommend `aptitude if you want to peek into the package structures a little bit. It most often gives you also good recommendations how to solve conflicts or insights why somethings fails in a quite readable manner.

If you are stuck and want a fresh start, just use the sdkmanager on your host computer to build a new fs image and flash it to the target.
