When cuda 11.6.1 is installed, tensorRT can only be installed in the tar method due to the dependency problem of installation. Isn’t this documentation incorrect?

Which TensorRT version is correct for Deepstream 6.1?
Or CUDA 11.6.1 version is wrong?
Please answer about my question.

Hi, @pngstar777 . So after cuda 11.6.1 is installed, what error was encountered with which installation command? Thanks

Hi, @yuweiw . There’s no error msg.

The guide document’s TensorRT version is
I have two questions.
Do you recommend TensorRT version? And can it be installed?
If version is recommended, is there a problem with the version of the guide document?

We suggest TensorRT as our guide says. You can find the version in our guide. We develop and debug the DeepStream 6.1 code in this env, so it could have better compatibility when you use the version we recommended. Thanks

  • Ubuntu 20.04
  • GStreamer 1.16.2
  • NVIDIA driver 510.47.03

Is there TensorRT for cuda11.6?
I can’t install TensorRT on my Ubuntu OS.

You can download the tensorrt and install it by dpkg command.
This combination for deepstream in our guide is QA verified. So we sugget you install it by referring our guide. Thanks

I tried this command. but tensorrt is installed on my Ubuntu OS.
How can I fix this Issue?

How do you intall tensorrt and cuda before? If you use apt-get install command, you can just use the apt-get pure command to remove the app.
