WebComputes CTC (Connectionist Temporal Classification) loss. Pre-trained models and datasets built by Google and the community WebIf you ran that script on a somewhat recent master, it could be a subtle problem: audiofile_to_input_vector no longer does the context windowing it used to do, it's now been moved to its callers. This means audiofile_to_input_vector(...).shape[0] is not the actual shape that gets fed to the acoustic model, you need to subtract the two empty context …
