Met error when running the example yolo of Deepstream 4.0

I download weights file and cfg file follow the readme file, then build the nvdsinfer_custom_impl_Yolo folder, run “deepstream-app -c deepstream_app_config_yoloV3.txt” but got an error.

error like bellow:

** Error: <parse_config_file:305>: parse_config_file failed
** Error: <main: 623>: failed to parse config file ‘deepstream_app_config_yoloV3.txt’
App run failed


We try the YOLO sample today and it works correctly.

Have you modified the configure file?
If yes, could you share the file with us?
