Hi,

This looks cool. Though weirdly I can't see the view window open up. All I get is:

pi@kobukiMxnet:~/edgetpu/python-tflite-source/edgetpu $ python3 demo/detect_capture_crop.py --model test_data/detect.tflite --label test_data/imagenet_labels.txt

Any idea why the view window won't open?

Also am I using the correct model. I downloaded from

https://www.tensorflow.org/lite/models/object_detection/overview#starter_model

Thanks
