"$ dpkg -l deepstream-5.0" no packages found matching deepstream-5.0

Hi @dusty-nv, I am learing how to use deepstream. Someone said if my jetpack version is over 4.5 then the deepstream 5.0 or above should be installed. But when I ran dpkg -l deepstream-5.0 on my terminal it showed no packages found matching deepstream-5.0. How do I know if deepstream sdk has been installed or not for sure?

@mmhzlrj DeepStream isn't installed by default - if you do apt-cache search deepstream, can you find it?

$ apt-cache search deepstream
deepstream-6.0 - Nvidia DeepStreamSDK runtime libraries, development files and samples

(this was on JetPack 4.6.1 / L4T R32.7.1)

[mmhzlrj]

@dusty-nv I ranapt-cache search deepstream and the result just like you said

jet@jet-nano:~$ apt-cache search deepstream
deepstream-6.0 - Nvidia DeepStreamSDK runtime libraries, development files and samples

Does it mean the DeepStream has been installed? Someone said I can located it from /opt/nvidia/deepstream and there are some samples I can try. But the deepstream folder doesn't exist. Would you mind to tell me where the installation path is? Or any recommendation for learning DeepStream?

[dusty-nv]

@mmhzlrj try sudo apt-get install deepstream-6.0

I'm not an expert on DeepStream, so I would post your questions to https://forums.developer.nvidia.com/c/accelerated-computing/intelligent-video-analytics/deepstream-sdk/15

If you prefer writing Python, I would check out these: https://github.com/NVIDIA-AI-IOT/deepstream_python_apps

Thank you @dusty-nv . After I running sudo apt-get install deepstream-6.0 to install DeepStream-6.0, I can see the deepstream folder under /opt/nvidia/. And I can run dpkg -l deepstream-6.0 to see more details:

Thanks for your recommendation, I will look it up.
