trt-yolo-app: /home/khlee/deepstream_reference_apps/yolo/lib/yolo.cpp:676: void Yolo::writePlanFileToDisk(): Assertion `!m_EnginePath.empty() && “Enginepath is empty”’ failed.
Aborted

I installed according to the instructions but encountered an error.

How to fix that?

Hi,

trt-yolo-app is integrated into our DeepstreamSDK here:
/opt/nvidia/deepstream/deepstream-4.0/sources/objectDetector_Yolo/

Would you mind to update to our new application instead.

Thanks.
