Deepstream-app: error while loading shared libraries: libyaml-cpp.so.0.6: cannot open shared object file: No such file or directory

I’m using the jetson Nano

Jetpack: 4.6
Tesorrt: 8.2.1.8-1+cuda10.2

After downloading DS 6.0.1 (.tbz file) (Which meets the requirements)
I try to run deepstream-app using the following command :

deepstream-app -c source12_1080p_dec_infer-resnet_tracker_tiled_display_fp16_tx2.txt

i get the following error :
deepstream-app: error while loading shared libraries: libyaml-cpp.so.0.6: cannot open shared object file: No such file or directory

Anyone has an idea how to solve this ?

Did you follow the installation guide? Quickstart Guide — DeepStream 6.0 Release documentation

Yes i have followed the guide, and made sure that DS 6.0.1 is the one that suits my setup, this might be related to the tensorrt and cuda version ?

Problem solved,
I made sure i have uninstalled the previous versions of deepstream (DS 6.1)
