Hi All,

I am following the python example about using nvdsanalytics for line crossing. I am looking for a method to reset the counter, specifically user_meta_data.objLCCumCnt) in pyds.NvDsAnalyticsFrameMeta in the probe. Simply setting the metadata to 0 does not work.

# both lines do not work with any error message.
user_meta_data.objLCCumCnt['Enter'] = 0
user_meta_data.objLCCumCnt = {'Enter': 0}

I have searched the python api document and I am not able to find anything related to resetting the counter.
Please kindly advise.

Cheers,
Fei

currenty deepstream dose not support to count objLCCumCnt from zero again on the fly.
here is a solution:
you might save the start value A and end value B, then get new objLCCumCnt
by “A-B”.
