RuntimeError: torchaudio.sox_effects.sox_effects.apply_effects_file requires sox解决

最近在训练数据集时，需要提取噪声的特征，代码如下：

 noise_waveform, noise_sr = torchaudio.sox_effects.apply_effects_file(noise_path, effects=[])

直接运行报错

利用Debug工具发现调用了torch.ops.torchaudio.sox_effects_apply_effects_file这个函数

    if not torch.jit.is_scripting():
        if hasattr(path, "read"):
            return torchaudio._torchaudio.apply_effects_fileobj(path, effects, normalize, channels_first, format)
        path = os.fspath(path)
    return torch.ops.torchaudio.sox_effects_apply_effects_file(path, effects, normalize, channels_first, format)

实际上torch.ops中并没有torchaudio，所以考虑可能是后面的版本并不支持这样操作，因为实际上我只需要得到噪声的wave以及采样率，所以可以直接调用torchaudio来操作，将代码改成以下这样：

# noise_waveform, noise_sr = torchaudio.sox_effects.apply_effects_file(noise_path, effects=[]) 不使用这个函数提取
noise_waveform, noise_sr= torchaudio.load(noise_path)

至此，问题解决。
总结：
有一些代码是过时或者依赖版本的，只有搞清楚代码在做什么事，善用debug工具才能更快解决问题。
