Ds-tao-detection -c pgie_dssd_tao_config.txt ..... report "terminate called after throwing an instance of 'YAML::BadFile'"

[xutao3]

I am testing the Deepstream_Tao_apps (GitHub - NVIDIA-AI-IOT/deepstream_tao_apps: Sample apps to demonstrate how to deploy models trained with TAO on DeepStream), and as the guide, I ran the command:
./apps/tao_detection/ds-tao-detection -c configs/dssd_tao/pgie_dssd_tao_config.txt -i file:///$DS_SRC_PATH/samples/streams/sample_720p.mp4

and reported following error:
(tao) nvidia@ubuntu:~/WS/TAO/deepstream_tao_apps$ ./apps/tao_detection/ds-tao-detection -c configs/nvinfer/dssd_tao/pgie_dssd_tao_config.txt -i file:///$DS_SRC_PATH/samples/streams/sample_720p.mp4
Request sink_0 pad from streammux
terminate called after throwing an instance of ‘YAML::BadFile’
what(): bad file: -c
Aborted (core dumped)

And it is same using the
/apps/tao_detection/ds-tao-detection -c configs/nvinfer/dssd_tao/pgie_dssd_tao_config.yml -i file:///$DS_SRC_PATH/samples/streams/sample_720p.mp4

However, it runs successfully the following command:
./apps/tao_detection/ds-tao-detection configs/app/det_app_frcnn.yml (enable the config-file-path: …/nvinfer/dssd_tao/pgie_dssd_tao_config.yml)

What’s the problem? Bug in code?

Will move to Deepstream forum for tracking.

It’s a bug, will be fixed next version. It’s open source, you can fixed it or try this patch.
