NPU Demo detect_demo_picture error

Hey, I use VIM3 pro to run NPU Demo
But I have a few problems.
When i run Detect_demo_picture with detect_demo_fb, my output is noisy like bellow image and i run with detect_demo_x11 and i get an error like this:
"W Detect_api:[det_set_log_level:19]Set log level=1
W Detect_api:[det_set_log_level:21]output_format not support Imperfect, default to DET_LOG_TERMINAL
W Detect_api:[det_set_log_level:26]Not exist VSI_NN_LOG_LEVEL, Setenv set_vsi_log_error_level
det_set_log_config Debug
det_set_model success!!


terminate called after throwing an instance of ‘std::logic_error’
what(): basic_string::_M_construct null not valid
Please help me to solve this problems. Thank you!
