CUDA not enable

[yunea01]

Hello. Yesterday, I downloaded the clone file and successfully installed it on the SD card. I checked that the opencv, pytorch, and torchvision files are installed using the import and print functions. However, when I import and check for CUDA enable with print output, it does not appear to be enabled. Is it like this in the clone file, or do I need to follow the steps mentioned in this link: https://github.com/Qengineering/Install-OpenCV-Jetson-Nano and reinstall? I'm new to Jetson Nano, can you help me with this?
