Accelerated Computing Intelligent Video Analytics DeepStream SDK

I am testing tracking.
Set 1 to useHighPrecisionFeature.

  useColorNames: 0     # Use ColorNames feature
  useHog: 0            # Use Histogram-of-Oriented-Gradient (HOG) feature
  useHighPrecisionFeature: 1   # Use high-precision in feature extraction. Default is [true]

Then enable-past-frame=1 in dstest2_tracker_config.txt.

I have error as

gstnvtracker: Batch processing is ON
gstnvtracker: *Past frame output is OFF*

!![ERROR] No visual feature types specified
An exception occurred. No visual feature types specified
terminate called after throwing an instance of 'std::exception'
  what():  std::exception
Aborted (core dumped)

Why I still have Past frame output is OFF?
What is the cause of error No visual feature types specified?
