python3-edgetpuvision and edgetpu-demo are broken (zeus)

[mirzak]

Trying to launch edgetpu-demo --stream, gives the following error:

The same applies for running e.g

edgetpu_classify \
--source /dev/video1:YUY2:1920x1080:30/1 \
--model models/mobilenet_v2_1.0_224_quant_edgetpu.tflite \
--labels models/imagenet_labels.txt

edgetpu_classify_server \
--source /dev/video1:YUY2:1920x1080:30/1 \
--model models/mobilenet_v2_1.0_224_quant_edgetpu.tflite \
--labels models/imagenet_labels.txt

Removing the usage of baseFunction it proceeds but then hits a new error

Error: gst-library-error-quark: Subclass failed to initialize. (3): ../../../../git/gst-libs/g

NameError: name 'ArrayDatatype' is not defined  

This looks like there is something wrong with the PyOpengl-accelerate recipe, but can not see what right now. This exists,

/usr/lib/python3.7/site-packages/OpenGL/arrays/arraydatatype.py

Above defines the ArrayDatatype class. So paths?

Any progress on this ?

[mirzak]

Not much unfortunately.
