Hello everyone! slash
I have a quite noob question. slash
I train deepspeech model on gpu, checkpoints are saved to the folder
'checkpoints'. slash
If I interrupt a training process, how can I use checkpoints of model to
make predictions? slash
For example, I want to see what model predicts to some wav-file. slash
I need to generate csv-file which describes this wav-file? And how to
check a model?

Thanks a lot for your attention, I will appreciate any help or link.

Haven't tried it myself but you can look inside
DeepSpeech.py, there's an option
'one_shot_infer' which should allow what you are looking for.

Alternatively, if you have specified the export_dir during your
training, the pb model that has been generated can be used with the
deepspeech-gpu command line utility that can be installed using pip.

pip install deepspeech-gpu
deepspeech-gpu models/output_graph.pb my_audio_file.wav models/alphabet.txt

That's correct, and if you keep the checkpoint dir, you should be able
to restart from the last epoch you stopped it.
