How to develop yolov7 with Jetson AGX ORIN?

How to develop yolov7 with Jetson AGX ORIN?
I installed via SDK Manager, but when i call the command python3 --weights --source 0 --device 0, error is - AssertionError: CUDA unaviable, invalid device 0 requested. Why doesn’t it show CUDA? How to solve the problem?

I call : show me.
nvcc --version:
Cuda compilation tools, release 11.4, V11.4.315
Build cuda_11.4.r11.4/compiler.31964100_0


When I do:
$ cd /usr/local/cuda/samples/1_Utilities/deviceQuery
$ sudo make
$ ./deviceQuery
./deviceQuery Starting…

i get following:
