hi, I downloaded and installed SDKmanager, but when I ran./sample_drivenet, an error occurred:

DW_CUDA_ERROR: Platform: cannot acquire cuda context: no CUDA-capable device is detected
terminate called after throwing an instance of ‘std::runtime_error’
what(): DW Error DW_CUDA_ERROR executing DW function:
dwInitialize(&m_sdk, DW_VERSION, &SDKParams)
at /dvs/git/dirty/gitlab-master_av/dw/sdk/samples/ drivenet /sample_drivenet/main.cpp:52
Aborted (core dumped)

So I reinstalled the graphics driver(430), but another error occurred:

Hi yu.zhang01,

We have DRIVE Software 10.0 release announced. Could you follow this page to upgrade to it first? Then try with its sample_drivenet.

Please note that there are some system requirements on the host machine.
