r“““Converts?a?trained?checkpoint?into?a?frozen?model?for?mobile?inference.

Once?you‘ve?trained?a?model?using?the?‘train.py‘?script?you?can?use?this?tool
to?convert?it?into?a?binary?GraphDef?file?that?can?be?loaded?into?the?Android

--window_stride_ms=10?--clip_duration_ms=1000?\
--model_architecture=conv?\
--start_checkpoint=/tmp/speech_commands_train/conv.ckpt-1300?\
--output_file=/tmp/my_frozen_graph.pb

One?thing?to?watch?out?for?is?that?you?need?to?pass?in?the?same?arguments?for
‘sample_rate‘?and?other?command?line?variables?here?as?you?did?for?the?training
script.

The?resulting?graph?has?an?input?for?WAV-encoded?data?named?‘wav_data‘?one?for
raw?PCM?data?（as?floats?in?the?range?-1.0?to?1.0）?called?‘decoded_sample_data‘
and?the?output?is?called?‘labels_softmax‘.
