PeopleNet not detecting bags

I tried to evaluate the trainable model directly using the Jupyter notebook for detectnet_v2. I used the command:

!tao detectnet_v2 inference -e $SPECS_DIR/my_inference.txt \
                            -o $USER_EXPERIMENT_DIR/my_data_testing \
                            -i $USER_EXPERIMENT_DIR/my_data \
                            -k $KEY

The folder my_data contains my testing photos. The variables are set in the section 0 in the Jupyter notebook. I ran whole this Jupyter notebook before and all seems to work there. The file my_inference.txt contains:

    }
  }
}

When I use this, all pictures are evaluated. Persons and faces are detected but no bags.


There are three thresholds. coverage_threshold, dbscan_min_samples and dbscan_confidence_threshold. If I set them all to 0, there are many detections. However, if I set any of those thresholds to 0.00000001, there are no bag detections at all. Persons and faces are detected normally.

I test it on 8 photos with 11 bags in total. None of them is detected, not even a single false-positive.

EDIT: I set the resolution to 940×544, still the same result
