I have successfully deployed and inference with Tacotron 2 and Waveglow in English, however when switching to Vietnamese model, I got an error when inference when client sent text with Vietnamese language characters. However the inference succeeded with English characters. I changed /models/tacotron2waveglow/config.pbtxt, /models/tacotron2waveglow/mapping.txt with Vietnamese characters, /engines and engines were converted from the Vietnamese Tacotron 2 model.
The error I got on the trtserver side: “Error Exception in CustomContext :: execute (): Could not find ‘(195)’ in the alphabet.”
Thanks for help!
basic_cleaners is just a “Basic pipeline that lowercases and collapses whitespace without transliteration” transliteration_cleaners is “Pipeline for non-English text that transliterates to ASCII.”
It’s recommended to use transliteration_cleaners for non-English text, but based on the use case you can experiment with basic_cleaners as well.
