[anurag.k]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Jetson Xavier
• DeepStream Version 6.1
• JetPack Version (valid for Jetson only) 35.1.0
• TensorRT Version 8.4.1.5
• Issue Type( questions, new requirements, bugs) Question

I am trying to run my python based Deepstream application on Jetson Xavier. I have followed the steps for Deepstream installation and the application is working fine on the host.

Now, when i try to dockerize and run the application using the below Dockerfile, I am getting errors. Details are below:

Please let me know how do I resolve this issue.

Can you confirm the same version and same installation steps can work on your Xavier?
Please be noted that BSP 35.1.0 comes together with JP5.0.2, and the corresponding DeepStream version is 6.1.1. But in your case it is 6.1, the versions seem to be a mismatch.

The same version is working on my Xavier. I have Deepstream6.1 with python bindings working on my machine.

If I upgrade to 6.1.1, do i need to change anything in the scripts?

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Could you try to use our docker directly to run the python demo? You can try to run it step by step in the demo docker and check whether there are still problems.
