我正在尝试编写一些代码，以便在colab主页中将MP3文件转换为midi。
所以我记得创建mp3格式的midi文件是一个大项目，我可能在将个人歌曲或音频文件导入这个项目时遇到了困难。(音频格式到MIDI，有些地方是用人工智能完成的(如PolyphonicPianoTranscription(，(音频到MIDI转换项目列表(。
因此，我尝试通过以下功能将MP3转换为WAV：
def MP3_to_WAV(MP3_file):
from pydub import AudioSegment
sound = AudioSegment.from_mp3(MP3_file)
filename = os.path.basename(MP3_file)
wav_file_name=output_path+filename.split('.')[0]+'.wav'
sound.export(wav_file_name, format="wav")
return wav_file_name
尝试通过这个指令和这个函数将WAV转换为MIDI：
def wav_to_midi(wav_f_n):
filename2 = os.path.basename(wav_f_n)
midi_file_name=output_path+filename2.split('.')[0]+'.midi'
run_comand("python /content/audio_to_midi_melodia/audio_to_midi_melodia.py "+wav_file+' '+ midi_file_name+" 120")
return midi_file_name
但是在我的colab页面(链接(的WAV到Midi块代码中，我得到了这个错误：

我想这一定是因为python版本不匹配，但在这里被问到了。
感谢您的关注。
看起来根本问题是Vamp::HostExt::PluginLoader: No library found in Vamp path for plugin "mtg-melodia:melodia"。
因此，要么需要将mtg mylia:modya的路径添加到Vamp路径，要么需要安装和配置mtg myria:modya。
看起来你正在使用以下url中的说明来设置mtg旋律。你能在那里重新检查一下mtg mylia的安装和配置细节吗？你可能错过了一个步骤
