Cannot open libcudla.so.1 when running deepstream-app

• Hardware Platform Jetson Orin
• DeepStream Version 6.3
• JetPack Version 5.1
• TensorRT Version 5.1

I’m configuring Jetson and although installation of TensorRT and DeepStream show no errors I get this error when trying to run test example:

deepstream-app: error while loading shared libraries: libcudla.so.1: cannot open shared object file: No such file or directory

Same error occurs when I try running trtexec. libcuda is installed, but not libcudla, output of ls -ll /usr/local/cuda/lib64/libcudla* command:

ls: cannot access ‘/usr/local/cuda/lib64/libcudla*’: No such file or directory

Is there some prerequisite I didn’t install?

I think this is because jetpack is not installed correctly, cuda is part of jetpack.

You can try to re-burn using nvsdkmanger.

You can try to re-burn using nvsdkmanger.

If I understood you correctly, you are suggesting that I reinstall entire OS on Jetson?

The problem is, I remotely access Jetson through TeamViewer, is there any other way to install missing libraries?

I am not sure your version of l4t, you can try the following command line.if it does not work, reinstall entire OS is necessary.

sudo apt update
sudo apt install nvidia-jetpack

Installing nvidia-jetpack installed libcudla.so.1, thanks.

However, when I try running examples, I get this:

It seems that nvosd, nvdsosd and nvinfer are not installed at all:

gst-inspect-1.0 nvosd
No such element or plugin ‘nvosd’

gst-inspect-1.0 nvdsosd
No such element or plugin ‘nvdsosd’

gst-inspect-1.0 nvinfer
No such element or plugin ‘nvinfer’

deepstream-app --version
deepstream-app version 6.3.0
DeepStreamSDK 6.3.0

jtop output:

jtop

It may be that the older jetpack version installed previously caused some plugins to not run properly.

gst-inspect-1.0 -b can see whether they are in the blacklist.

Run the install.sh script in the /opt/nvidia/deepstream/deepstream directory, clearing the cache should solve this problem.

After running install.sh script, examples work fine now, thanks.
