Is it possible to run DeepSpeech on a EdgeTPU board? I’ve been trying to compile the tflite model use
edgetpu_compile but encountered couple of errors.
I followed the instructions here to do a full integer quantization, but it gives the following error:
RuntimeError: Quantization not yet supported for op: CUSTOM
I suppose this is due to AudioSpectrogram and Mfcc ops.
The error is gone if I remove:
converter.target_spec.supported_ops = [tf.lite.OpsSet.TFLITE_BUILTINS_INT8]
But the output model is not recognized as quantized by
edgetpu_compile, it complains
Model not quantized when I tried to compile it. It makes sense since the model is full integer quantized.
