Deepstream-test1-app terminates with YAML::Badfile

[steven.sparks]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson AGX Orin developer kit)
• DeepStream Version 6.3.0
• JetPack Version 5.1.2-b104
• TensorRT Version 8.5
• Issue Type( bugs)
• How to reproduce the issue ? (compiled deepstream_test1_app.c using Makefile, …/deepstream-test1$ ./deepstream-test-1app dtest1_config.yml)

ORIN just successfully flashed and included Deepstream 6.3 in flash.
Compiled deepstream_test1_app.c using Makefile with modified CUDA_VER=11.4.
Ran executable with dtest1_config.yml in deepstream_test1 directory.

Error message:
terminate called after throwing an instance of ‘YAML::Badfile’
what(): bad file
Aborted (core dump)

Any ideas.

Did you change something in dstest1_config.yml ? Looks like a yaml config file error.

You can check your yaml file with this

Have not made any changes on purpose to any of the code in test 1 except the one change to the Makefile for CUDA version. Its all pristine.

Checked dstest1_pgie_config.yml and dstest1_config.yml with YAML Lint and
it indicated both are “Valid YAML!”.

After adding print statements in code (in attempt to debug) and recompiling, I don’t get the error now. I don’t think adding the print statements had anything to do with fixing the issue. I’ll keep an eye on the sequence I use to modify, compile, and whatnot.
If I discover before issue is closed I’ll add my findings. So strange.

Thanks for you time. Did learn about YAML Lint tool. Thanks!
