How to view output

[matsavage]

Setup: Coral Dev board, freshly flashed with enterprise-eagle-20200724205123

I can't seem to view the output of the pose_camera.py example, when I run this script on my dev board, with HDMI attached I only get text outputted to the console with no video window present.

mendel@red-kid:~/project-posenet$ python3 pose_camera.py 
/home/mendel/project-posenet/gstreamer.py:15: PyGIWarning: Gst was imported without specifying a version first. Use gi.require_version('Gst', '1.0') before import to ensure that the right version gets loaded.

                  ! video/x-raw,format=RGB,width=641,height=481 ! appsink name=appsink emit-signals=true max-buffers=1 drop=true

Also when I run the simple_pose.py script, I get the expected coordinates, so I am confident that the model etc is all working fine.

Am I intended to connect to the dev board with GStreamer? Is there a guide on how to do this anywhere?

Many thanks

The problem was that I had connected the ribbon cable for the camera upside down, connecting it the right way up fixed the issue
