you can change readme from

export YOLO_ROOT=pwd/deepstream_reference_apps/yolo
to
export YOLO_ROOT=$PWD/deepstream_reference_apps/yolo

I think they updated the deepstream reference apps repo there is no directory called "yolo" in it.

hi mosh,

thanks for creating this awesome wrapper. i am having the following trouble running it though:

Traceback (most recent call last):
File "t.py", line 7, in
lib=CDLL('./libyolo.so')
File "/usr/lib/python3.6/ctypes/init.py", line 348, in init
self._handle = _dlopen(self._name, mode)
OSError: ./libyolo.so: undefined symbol: _ZN2cv7putTextERKNS_17_InputOutputArrayERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEENS_6Point_IiEEidNS_7Scalar_IdEEiib

do you have an idea of what could e the cause.

i am also wondering if it could run on a video?

thanks

Hi @mosheliv,

Look like the step no 6 for the link is wrong for deepstream_reference_apps/yolo/apps/trt-yolo/CMakeFiles/trt-yolo-app.dir/flags.make, should it deepstream_reference_apps/yolo/apps/trt-yolo/build/CMakeFiles/trt-yolo-app.dir/flags.make ?

Basically I am trying to load 2 different tiny-yolov3 models to memory and do inference depending on the situation. However, when I try to load 2 different yolo models in the same python script, library messes up the memory locations and fails.

Any help would be appreciated. I will post if I come up with a solution

I have compiled opencv from source and still it's not finding the path, anyone please ?

after running this: make && sudo make install

I've got this error :

jetson-nano@jetsonnano-desktop:~/deepstream_reference_apps/yolo/apps/trt-yolo/build$ cmake -D CMAKE_BUILD_TYPE=Release ..

Please help me figure this out.

How can I use cuda 10.2 instead of cuda 10.0 ?

Hi @mosheliv,

In step 9 cd apps/trt-yolo/lib. in my case, there is lib folder. It exist in apps/trt-yolo/build/lib or https://github.com/NVIDIA-AI-IOT/deepstream_reference_apps/tree/master/yolo/lib . so which lib did you mean?

Hi, I was wondering if there is an example on how to use it. I'd like to extract the data (class name,location) of each detection.

Thanks for your help.
