how can I solove this**

Can you describe how you installed DeepStream 6.1.1 on your Orin?
Here is the installation guide on Jetson for your reference ( Quickstart Guide — DeepStream 6.1.1 Release documentation (nvidia.com))

[lokinfey]

yes i follow install guidline ， but can not run

[yingliu]

Seems CUDNN is not installed correctly in your setup, how did you install deepstream on your Orin setup? use SDKManager, tar package or deb package?
Not sure if your cudnn and tensorrt installed correctly, please check version on your system:
dpkg -l |grep -i tensorrt
dpkg -l |grep -i cudnn

Suggest using SDKManager to reinstall CUDA-X and DeepStream.

[lokinfey]

I check this , is it okay ?

[lokinfey]

it can not run … coz I confirm all settings

[yingliu]

The packeges seem to be OK, what’s the output of “deepstream-app --version-all”?

[lokinfey]

[lokinfey]

I set all ， but the errors 。。。。。。

[fanzh]

is there still “Error Code 1: Cudnn (Could not initialize cudnn, please check cudnn installation.)”? if yes, it should be driver version is not compatible with cudnn. could you share the output of nvidia-smi?

[lokinfey]

I think jetson nx can not install nvidia-smi

[fanzh]

ok, is there libcudnn.so.8 on the jetson? you can get the path after do ldd /usr/src/tensorrt/bin/trtexec, or Have you tried reinstalling?

[lokinfey]

@fanzh

/usr/src/tensorrt/bin/trtexec

yes confirm all is here , I have try to reinstall, but can not run

[fanzh]

@lokinfey

yes i follow install guidline ， but can not run

how did you install on you jetson nx? here is the recommendation docs: https://developer.nvidia.com/embedded/jetpack#collapseJetsonXavierNX

JETSON XAVIER NX DEVELOPER KIT >

after installing , what is the output of “ldd /usr/src/tensorrt/bin/trtexec” and " /usr/src/tensorrt/bin/trtexec" ?

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