GPU multiprocess error

[deryaguler95]

I got below error. raise ProcessRaisedException(msg, error_index, failed_process.pid) torch.multiprocessing.spawn.ProcessRaisedException: -- Process 1 terminated with the following error: raise exception KeyError: Caught KeyError in DataLoader worker process 0. Original Traceback (most recent call last): sequence = [_symbol_to_id[symbol] for symbol in cleaned_text] KeyError: '1'

O could not fix that. Are there any idea?

It seems that your training dataset includes digits, "1" specifically.

• The optimal way to solve it would be to convert all numbers in dataset from digit representation into letter representation (f.e. "1" -> "one"). This is tedious, but will give the optimal inference results.

• Alternatively, you can just add numbers to text/symbols.py file. Something like that:

""" from https://github.com/keithito/tacotron """

'''
Defines the set of symbols used in text input to the model.
'''
_pad        = '_'
_punctuation = ';:,.!?¡¿—…"«»“” '
_letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
_letters_ipa = "ɑɐɒæɓʙβɔɕçɗɖðʤəɘɚɛɜɝɞɟʄɡɠɢʛɦɧħɥʜɨɪʝɭɬɫɮʟɱɯɰŋɳɲɴøɵɸθœɶʘɹɺɾɻʀʁɽʂʃʈʧʉʊʋⱱʌɣɤʍχʎʏʑʐʒʔʡʕʢǀǁǂǃˈˌːˑʼʴʰʱʲʷˠˤ˞↓↑→↗↘'̩'ᵻ"
_numbers = "1234567890"

# Export all symbols:
symbols = [_pad] + list(_punctuation) + list(_letters) + list(_letters_ipa) + list(_numbers)

# Special symbol ids
SPACE_ID = symbols.index(" ")
