CUDA 11.8 버전 쓰고 있어서

    pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118 
    

설치했으나 C컴파일을 요구해서 Vistual Studio Community 설치.

아래보고 참조함

FAIRSEQ 관련 오류는

      note: This error originates from a subprocess, and is likely not a problem with pip.

이런 것이었는데 버전이 git+https 로 되어있던 requirements.txt 중 `fairseq @ git+https://github.com/One-sixth/fairseq.git` 이 부분을 그냥 `fairseq` 로 변경

일단 넘어는 갔다.

\`python infer.py

로 추론을 해보니

    converted_out\174-50561-0000.wav
    converted_out\652-129742-0000.wav
    converted_out\777-126732-0000.wav

    converted_out\7850-73752-0000.wav
    converted_out\8842-302196-0000.wav
    

파일이 잘 생성된다.

흠.. 실시간 생성은 어떻게 하는거지? -s 옵션 준다고 되진 않네.
