Inconsistent CUDA installation instructions

I have come across at least three sets of CUDA toolkit installation instructions for WSL2 on various NVIDIA websites.

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=WSLUbuntu&target_version=20&target_type=runfilelocal

which one should be followed for correct installation? Assuming WSL2 and NVIDIA drivers are already set up correctly.

I have worked through all of these instructions. All of them were failed to enable GPU acceleration in Tensorflow 2

I can confirm that the user guide works

tested by running sudo make in /usr/local/cuda/samples/1_Utilities/deviceQuery, followed by ./deviceQuery

I have not tried the instructions in the other two links I posted originally. Not tried tensorflow or any docker containers.
