FileNotFoundError: [Errno 2] No such file or directory: 'samples/6829_00000.mp3'

Dear @padmalcom,

I am trying to set up and run the Real-Time Voice Cloning (German) project on my system, but I keep encountering a FileNotFoundError related to missing audio files in the samples directory. Here is the exact error message I am receiving:

Traceback (most recent call last):
  File "C:\Users\Utente\miniconda3\envs\rtvc\lib\site-packages\librosa\core\audio.py", line 149, in load
    with sf.SoundFile(path) as sf_desc:
  File "C:\Users\Utente\miniconda3\envs\rtvc\lib\site-packages\soundfile.py", line 629, in __init__
    self._file = self._open(file, mode_int, closefd)
  File "C:\Users\Utente\miniconda3\envs\rtvc\lib\site-packages\soundfile.py", line 1183, in _open

    raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace'))
RuntimeError: Error opening 'samples/6829_00000.mp3': System error.

During handling of the above exception, another exception occurred:

Steps to Reproduce:

1. I installed the project following the instructions and set up the Conda environment using environment.yml.
2. I downloaded the pre-trained models from this page and placed them in the appropriate subfolders as per the instructions:
   • encoder/saved_models/encoder.pt
   • synthesizer/saved_models/synthesizer.pt
   • vocoder/saved_models/vocoder.pt
3. I tried running demo_toolbox.py.
4. The script fails with the above error indicating a missing file (samples/6829_00000.mp3).

What I’ve Tried:

• I’ve checked the samples directory, but the file 6829_00000.mp3 doesn’t exist.
• I attempted using a different .mp3 file, but I am not sure what format or content is expected for this audio file.
• I have librosa, audioread, and soundfile installed correctly, as the script falls back to audioread without issues, but I believe it’s more of a file path issue.

Additionally, I ran the following command:

python mailab_normalize_text.py --datasets_root de_DE

And the output was:

Searching speakers...
[]
Checking subfolders...
Found 0 wav folders
[]
Wrote 0 files.

Environment:

• OS: Windows 10
• Python: 3.7 (via Miniconda)
• Librosa version: 0.8.0
• Soundfile version: 0.10.3
• Audioread version: 2.1.9
• Project branch: master

---

Could there be an issue with the way librosa or audioread is trying to handle .mp3 files?
For the mailab_normalize_text.py script, why is it not finding any .wav files or speakers? How should the dataset be organized for this script to work correctly?

Thank you for your help!
Any guidance on how to resolve these issues would be much appreciated.

Best regards,
