MP3 to midi converting by python (TypeError: Failed to load plugin: mtg-melodia:melodia)

I am trying to write some codes to convert MP3 files to midi in the main colab page.

so i remember that creating midi file form mp3 is a big project, and I probably have trouble importing a personal song or audio file into this project. (Audio format to MIDI, in some places is done with artificial intelligence (such as PolyphonicPianoTranscription), (list of AudiotoMIDI conversion projects).

So i have tried to convert the MP3 to WAV by this function:

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

and the tried to convert The WAV to MIDI by this instruction and this function:

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

but in the WAV to Midi Block codes of my colab page (link),i get this error:

TypeError: __init__() takes 2 positional arguments but 4 were given

I guess it must happened because of the python version mismatching, but is asked here.

Thanks for your attention.

To install a plugin set, copy the plugin's library file and any supplied category or RDF files into your system or personal Vamp plugin location.

The plugin file extension and the location to copy into depend on which operating system you are using:

Your operating systemFile extension for pluginsWhere to put the plugin filesmacOS.dylibOn a Mac:
  • Put plugins for all users to use in /Library/Audio/Plug-Ins/Vamp
  • Put plugins for only the current user in $HOME/Library/Audio/Plug-Ins/Vamp
  • The Library folders are hidden by default; see here for details of how to show them
64-bit Windows.dllWhen using a 64-bit version of Windows:
  • Put 32-bit plugins in C:\Program Files (x86)\Vamp Plugins
  • Put 64-bit plugins in C:\Program Files\Vamp Plugins
  • Both 32-bit and 64-bit plugins can be used, as long as you put them in the right places as above
  • If a plugin package is not described as 64-bit, then it is a 32-bit plugin. Some older plugins were only published in 32-bit form.
32-bit Windows.dllWhen using a 32-bit version of Windows:
  • Put 32-bit plugins in C:\Program Files\Vamp Plugins
  • You cannot use 64-bit plugins at all on 32-bit Windows
  • If a plugin package is not described as 64-bit, then it is a 32-bit plugin. Some older plugins were only published in 32-bit form.
Linux, other Unix.soOn Linux, BSD systems, etc:
  • Put plugins for all users to use in /usr/local/lib/vamp
  • Put plugins for only the current user in $HOME/vamp
  • Only plugins with the correct architecture can be used (32-bit plugins on 32-bit systems, and 64-bit on 64-bit).

You can alternatively set the VAMP_PATH environment variable to override the search path for for Vamp plugins. VAMP_PATH should contain a semicolon-separated (on Windows) or colon-separated (macOS, Linux) list of directory locations. If it is set, it will completely override the standard locations listed above. (N.B. When using 32-bit plugins on 64-bit Windows, some hosts will check for the VAMP_PATH_32 environment variable instead of VAMP_PATH.)

It looks like the root problem is Vamp::HostExt::PluginLoader: No library found in Vamp path for plugin "mtg-melodia:melodia".

So either mtg-melodia:melodia's path needs to be added to Vamp path, or mtg-melodia:melodia needs to be installed and configured.

It looks like you are using the instructions from the following url to set up mtg-melodia. Could you recheck there for mtg-melodia install and configure details, there may have been a step you missed.
