Blazeface back camera model (quantized)

[metanav]

I could not find any quantized version for face_detection_back.tflite model.

The model before quantization is not available in either the mediapipe or tfjs repositories, so it cannot be generated.

You can find FP32 model here: https://github.com/google/mediapipe/blob/master/mediapipe/models/face_detection_back.tflite

How did you generate for "front" one?

[PINTO0309]

This is a model quantized to Float16. The Back model is a new model that was added 21 days ago. The Float32 model was not committed from the beginning.

How did you generate for "front" one?

I took the Float32 model from a commit older than 22 days ago and quantized it.

[metanav]

I see! I have asked them to share the FP32 or saved model. It seems they are not willing to do so.

Can the edge tpu quantized model be run without the coral edge accelerator? I mean only on Raspberry Pi.

[PINTO0309]

It does not work because it contains a dedicated EdgeTPU custom OP.

[metanav]

That's what I thought.

The situation is closed as there is no room for improvement. Issue another issue if necessary.
