Problem with NvDCF tracker on deepstream 5.0 and jetson

Hello,

I’m trying to run NvDCF tracker on a deepstream app on jetson AGX, but the app suddenly stops in the beginning showing the below errors and warnings.

I’m using yolo3-tiny as a detector and this is the config file of the tracker :

[tracker]
tracker-width=960
tracker-height=544
gpu-id=0
ll-lib-file=/opt/nvidia/deepstream/deepstream-5.0/lib/libnvds_nvdcf.so
ll-config-file=tracker_config.yml
enable-batch-process=1

Also this is the app config file:

gie-unique-id=1
batch-size=1

I commented minMatchingScore4Motion and matchingScoreWeight4Motion in tracker_config.yml, the error has changed to:

However, I tried to run source12_1080p_dec_infer-resnet_tracker_tiled_display_fp16_tx2.txt example with NvDCF tracker and I worked. I’m not really sure what caused the problem. I also tried to run my app without tracker_config.yml and it worked. So, anyone know what is the reason behind it? Also is the tracker very slow or there is something wrong with it?

I’m using Python version of deepstream.

I manage to solve the problem by commenting endFrameNum: 200 line in tracker_config.yml.
