PyDub AudioSegment未能加载有效文件

Question

我使用Python来操作WAV文件。此代码用于：

from pydub import AudioSegment

fp = "/Volumes/.../generic.wav"
sound = AudioSegment.from_wav(fp)

现在我得到了一个错误：

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/pydub/audio_segment.py", line 670, in from_file
    return cls._from_safe_wav(file)
  File "/usr/local/lib/python3.7/site-packages/pydub/audio_segment.py", line 818, in _from_safe_wav
    file.seek(0)
AttributeError: 'NoneType' object has no attribute 'seek'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "cassandra.py", line 992, in md2episode
    sound = AudioSegment.from_wav(fp)
  File "/usr/local/lib/python3.7/site-packages/pydub/audio_segment.py", line 808, in from_wav
    return cls.from_file(file, 'wav', parameters=parameters)
  File "/usr/local/lib/python3.7/site-packages/pydub/audio_segment.py", line 678, in from_file
    file.seek(0)
AttributeError: 'NoneType' object has no attribute 'seek'

该文件播放它的22秒，使用ffprobe检查它似乎还可以：

我已经检查过pydub是最新的：

$ python3 -m pip install --upgrade pydub
Requirement already up-to-date: pydub in /usr/local/lib/python3.7/site-packages (0.25.1)

我的Python版本是：

$ python3 --version
Python 3.7.9

如何使用PyDub加载WAV文件？或者我在哪里能找到一个等价的替代品呢？

今天我不能再重复这个问题了。输入文件是Google语音合成的结果，所以这可能是一个错误。今天再次运行代码解决了问题。
