I installed CUDA 11.2 and realised that's not the version I wanted... Then I uninstall it via Control Panel "Uninstall a Program" and uninstall all CUDA 11.2 stuff(but I didn't uninstall those Nvidia Nsight stuff)
After that I install CUDA 10.2, but as I key in below 2 commans, both showed me different CUDA verisons. I'm using Windows 10, with GeForce GTX 1650.

10.2 and 11.2... Any idea on this?
Thank you!!
nvidia-smi shows the highest version of CUDA supported by your driver. nvcc shows the version of the current CUDA installation. As long as your driver-supported version is higher than your installed version, it's fine. You can even have several versions of CUDA installed at the same time.
