Hi,
Can you provide comlete log when error happened?

GalibaSashi · July 30, 2020, 2:48am

Any command to gove before running deepstream-app to get the log?

GalibaSashi · July 30, 2020, 4:21am

Kindly see the log here

Amycao · July 30, 2020, 7:43am

Did you use original model or customized model?

GalibaSashi · July 30, 2020, 7:48am

Hi @Amycao,
This is same as specified in README

Amycao · July 31, 2020, 6:36am

Can you provide below info:
• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)

GalibaSashi · July 31, 2020, 6:37am

dGPU t4
Deepstream 5.0
Tensorrt 7.0
440

Amycao · July 31, 2020, 7:17am

I see you using engine, can you run success with TensorRT sample trtexec?

GalibaSashi · July 31, 2020, 7:19am

yes I even get output video correctly in Deepstream but segmentation fault comes

Amycao · July 31, 2020, 7:25am

How you build the engine?
the segmentation should be caused by “Cannot find binding of given name: MarkOutput_0”

GalibaSashi · July 31, 2020, 7:28am

Using the readme in the object detector SSD folder. Actually before creating the model engine files i.e running for the first time segmentation fault doesnt appear. But after creating engine file and running again the error appears

Amycao · July 31, 2020, 7:31am

Can you remove the cache for gstreamer and try again?
rm ~/.cache/gstreamer-1.0/ -rf

Can you move to DS 5.0GA to see if the issue still there, if does, we will see you there.

GalibaSashi · August 7, 2020, 9:44am

I am using the same DS 5.0

Amycao · August 24, 2020, 10:04am

Please using 5.0 GA, the previous version is 5.0 DP
