• Hardware Platform (Jetson nano)
• DeepStream Version5.1
• JetPack Version (4.6)
• 8.0
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• Install deepstream to run the test statements inside:deepstream-app -c source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt
i saw thiserror:deepstream-app: error while loading shared libraries: libnvinfer.so.7: cannot open shared object file: No such file or directory,
and i run deepstream-app --version-all，the error is same.I’ve added tensorrt paths to the environment variables

Sorry for the late response, is this still an issue to support? Thanks

Jetpack 4.6 support Deepstream 6.0

thanks so much ， i have solved this problem.I ran into the following issues using my own model to deploy via deepstream：Failed to create NvDsInferContext instance .

• yolov5-5.0
• jetpack-4.4
• deepstream-5.0
• Tensorrt-7.1
• Cuda-10.2

Perform the last step:LD_PRELOAD=./libmyplugins.so deepstream-app -c deepstream_app_config_yoloV5.txt

I received the following error：
