试图将一个大的（可能非常）不可拾取的对象渲染到文件中，以供以后使用。dill.dump(file)方面无投诉：
In [1]: import echonest.remix.audio as audio
In [2]: import dill
In [3]: audiofile = audio.LocalAudioFile("/Users/path/Track01.mp3")
en-ffmpeg -i "/Users/path/audio/Track01.mp3" -y -ac 2 -ar 44100 "/var/folders/X2/X2KGhecyG0aQhzRDohJqtU+++TI/-Tmp-/tmpWbonbH.wav"
Computed MD5 of file is b3820c166a014b7fb8abe15f42bbf26e
Probing for existing analysis
In [4]: with open('audio_object_dill.pkl', 'wb') as f:
...: dill.dump(audiofile, f)

In [5]:
但是尝试加载
.pkl文件：In [1]: import dill
In [2]: with open('audio_object_dill.pkl', 'rb') as f:
...: audio_object = dill.load(f)
...:
返回以下错误：

AudioObject比（从SO answer）进行上述调用的
class object复杂得多（并且很大），我不清楚是否需要通过dill发送第二个参数，以及是否因此，该参数将是什么，或者如何判断对该特定对象是否可行的酸洗方法。检查一下对象本身：
In [4]: for k, v in vars(audiofile).items():
...: print k, v
...:
返回：
is_local False
defer False

并且
audiofile.analysis似乎包含一个称为audiofile.analysis.source的属性，该属性包含（或显然指向） 最佳答案
在这种情况下，答案就在模块本身之内。LocalAudioFile类提供（并且每个实例都可以利用）它自己的save方法，该方法通过LocalAudioFile.save或更可能是the_audio_object_instance.save调用。
如果是.mp3文件，则LocalAudioFile实例包括指向临时.wav文件（该文件是.mp3的解压缩版本）的指针，以及从其中返回的所有分析数据。与基于Internet的Echonest API接口后的初始音频文件。
LocalAudioFile.save调用shutil.copyfile(path_to_wave, wav_path)以与链接到音频对象的原始文件相同的名称和路径保存.wav文件，如果该文件已经存在，则返回错误。它调用pickle.dump(self, f)将分析数据保存到一个文件中，该文件也位于调用原始音频对象文件的目录中。
可以简单地通过LocalAudioFile重新引入pickle.load()对象。
这是我使用iPython的dill会话，这是一个非常有用的包装器或接口，它提供大多数标准的pickle方法以及更多其他方法：
audiofile = audio.LocalAudioFile("/Users/mikekilmer/Envs/GLITCH/glitcher/audio/Track01.mp3")
In [1]: import echonest.remix.audio as audio
In [2]: import dill
# create the audio_file object

Echonest是非常健壮的API，并且remix包提供了大量功能。在here汇编中有一小部分相关链接。
