一 问题描述

 OSError: [Errno 117] Structure needs cleaning: '/tmp/pymp-wafeatri'

        我重新使用SSH登录也会提示这个类似问题

二 解决方法

2.1 尝试删除报错的文件 （想直接看最终解决方法的可忽略此处）

   sudo rm -rf /tmp/pymp-wafeatri

        此种方法只能保证当前epoch不报错，下一个epoch依然会报错。（不好用）

2.2 定位原始代码

        定位到使用系列临时文件夹的代码66行、67行；

#修改前源代码
def repitch(wav, pitch, tempo, voice=False, quick=False, samplerate=44100):
    """
    tempo is a relative delta in percentage, so tempo=10 means tempo at 110%!
    pitch is in semi tones.
    Requires `soundstretch` to be installed, see
    https://www.surina.net/soundtouch/soundstretch.html
    """
    infile = tempfile.NamedTemporaryFile(suffix=".wav")
    outfile = tempfile.NamedTemporaryFile(suffix=".wav")
    save_audio(wav, infile.name, samplerate, clip='clamp')
    command = [
        "soundstretch",
        infile.name,
        outfile.name,
        f"-pitch={pitch}",
        f"-tempo={tempo:.6f}",
    ]
    if quick:
        command += ["-quick"]
    if voice:
        command += ["-speech"]
    try:
        sp.run(command, capture_output=True, check=True)
    except sp.CalledProcessError as error:
        raise RuntimeError(f"Could not change bpm because {error.stderr.decode('utf-8')}")
    wav, sr = ta.load(outfile.name)
    assert sr == samplerate
    return wav

        解决方法：修改代码，设置delete=False，添加try-except-finally，在finally中手动关闭文件，删除文件。保证即使报错也能正常关闭文件，删除文件。
