Error in building TensorFlow Object Detection Demo

[hramireddy1]

I was able to build and run the hello_world example on Desktop.

When i try to build the object detection demo using

$ bazel build -c opt
--define MEDIAPIPE_DISABLE_GPU=1
--define no_aws_support=true
mediapipe/examples/desktop/object_detection:object_detection_tensorflow

I receive the following errors:

The errors look like download issues with your network connection. Are you blocked by firewall? Are you in China? Pls retry this from another network condition.

Hi mgyong,
Thank you for your suggestion.

I tried from a different network and the build started and it went on until the end and at last this error showed up.

MediaPipe tries to use your local OpenCV libraries but gets undefined references. How do you install OpenCV? Via package manager or the script? You probably can find some useful instructions in install.md.

Hi,

My bad. I changed the WORKSPACE and opencv_linux.BUILD but it was not pointing to the correct location. It is working now.
Thank you.
