Hi finally managed to compile the hello world example. Now compiled object\_detection:object\_detection\_cpu. How do i run it?

I tried this:

```
C:\_Research\mediapipe-od-build\mediapipe\bazel-bin\mediapipe\examples\desktop\object_detection>object_detection_cpu.exe --calculator_graph_config_file=C:\_Research\mediapipe-od-build\mediapipe\mediapipe\modules\object_detection\object_detection_cpu.pbtxt

I am using pycharm with the official mediapipe package and all solutions work just fine. is there a way to add your object detection part manually to the package?

I am not giving up yet:) but its pretty frustrating.

Also i can not find the binarypb file for object detection created anywhere. When building other examples like pose or hand there are also binarypb files created in bazel-out modules folder.
