Hi,

 

I can't get the Object detection with TensorFlow Lite demo running on the RB5.

I have downloaded everything and it seems to have compiled, however, the program does not run correctly. A window with a video feed is displayed without the object detection. The following error message is shown:

 

Loading model: mobilenet_quant_v1_224.tflite
 
(process:17830): GStreamer-CRITICAL **: 16:23:46.387: gst_element_get_state: assertion 'GST_IS_ELEMENT (element)' failed

ERROR: Subgraph is already in use.

I am using an RB5 board which has been updated using apt-get with a Microsoft webcam.
 
Thanks in advance for any help.

Please check whether you had multiple gstreamer processors: ps -A

Please upload your gstreamer command.
