[Bug] Unable to initialize a LibriTTS Dataset with the Python Trainer API?

[stanleyshly]

When setting up LibriTTS with dataset_config = BaseDatasetConfig(name="libri_tts", path=os.path.join(output_path, "../LibriTTS/train-clean-100/")), I get this error:

Traceback (most recent call last):
File "train_fast_speech.py", line 78, in
train_samples, eval_samples = load_tts_samples(dataset_config, eval_split=True)
File "/home/workstation/.local/lib/python3.8/site-packages/TTS/tts/datasets/init.py", line 111, in load_tts_samples
meta_data_train = formatter(root_path, meta_file_train, ignored_speakers=ignored_speakers)
File "/home/workstation/.local/lib/python3.8/site-packages/TTS/tts/datasets/formatters.py", line 249, in libri_tts
assert os.path.exists(item[1]), f" [!] wav files don't exist - {item[1]}"
KeyError: 1
I placed the LibriTTS folder on branch up of the trainer script(exit one folder, and placed the LibriTTS dataset folder there), so I am not sure why it is not working.
