This is the config file for tracker. You can refer to the config file starting with souce*.

You can try command below for test local file as input

deepstream-app -c source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.yml

You can got more information from here

Thanks

I am getting this error after running above command

Looks like there is a problem with your gpu driver.
Please reference this document to install dependencies

I strongly recommend you to use docker.
Here is the installation manual

Thanks

I will say by example:
deepstream-app -c source4_1080p_dec_preprocess_infer-resnet_preprocess_sgie_tiled_display_int8.txt
This works perfectly on my local machine setup but not on docker.
Similarly I was trying to run this
deepstream-app -c source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.yml
I am unable to run it either on my local machine setup or in Docker.

8

Did you run “xhost + ” before launching the docker?
This is required as mentioned in DeepStream | NVIDIA NGC

Can you provide log after export GST_DEBUG=3 ?

9

after doing xhost+
I ran docker
then deepstream-app -c source4_1080p_dec_preprocess_infer-resnet_preprocess_sgie_tiled_display_int8.txt
Getting error
** ERROR: main:733: Could not open X Display

10

How you ran docker ? can you provide the command line

Recommended:

docker run --gpus all -it --rm --net=host --privileged -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -w /opt/nvidia/deepstream/deepstream-6.2 nvcr.io/nvidia/deepstream:6.2-devel

what do you see from “echo $DISPLAY ”?
If there is no content
export DISPLAY=:0 or 1 // xrandr to check display environment exported or not.

If still not working, Please provide log after export GST_DEBUG=3.

I was running docker like this
docker run -it --gpus all nvcr.io/nvidia/deepstream:6.2-samples
so got error after running DeepStream sample inference

Then I ran docker like this
docker run --gpus all -it --rm --net=host --privileged -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -w /opt/nvidia/deepstream/deepstream-6.2 nvcr.io/nvidia/deepstream:6.2-samples
Then I ran these following sample inferences and they are running fine
deepstream-app -c source4_1080p_dec_preprocess_infer-resnet_preprocess_sgie_tiled_display_int8.txt

deepstream-app -c source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.yml

However this deepstream-app -c source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.yml is not running on my local setup

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

As mentioned above, please add GST_DEBUG=3 ahead of deepstream-app and test it again on your local host, the log will provide more information on why it fails.
