ctypes.cdll error

[gvossos]

Hi, I'm unable to run sample scripts on Windows 11 using Python 3.11.8.

Python throws --> ctypes.CDLL(lib_path) error,
--> musiclang\Lib\ctypes_init_.py", line 376, in init
self._handle = _dlopen(self._name, mode),
--> FileNotFoundError: Could not find module '....\musiclang\Lib\site-packages\musiclang_predict\c\run.dll' (or one of its dependencies). Try using the full path with constructor syntax.

Any suggestions?

Same issue.
windows 11.
git cloned the repo
cd'd into it
created a virtual environment: python -m venv venv
activated the environment: venv\Scripts\activate
created a test.py with the github basic script contents word for word.
ran it and after it downloaded the model etc I got:

(venv) D:\AI\musiclang_predict>python test.py
Traceback (most recent call last):
  File "D:\AI\musiclang_predict\test.py", line 9, in <module>

    return ctypes.CDLL(lib_path)

    self._handle = _dlopen(self._name, mode)
FileNotFoundError: Could not find module 'D:\AI\musiclang_predict\musiclang_predict\c\run.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I noticed in the readme it says to pip install it rather than clone it. so i tried that with a freshfolder, fresh virtual environment and got the following error:

Side note: when going to get the error code again to share here, I forgot to activate my virtual environment.... that may end up being a costly mistake... time will tell but it does show its not the virtual environment effecting it.

I don't currently own a windows laptop so it's hard for me to debug that.
I don't know if the setup is failing for everyone on this os. If someone managed to get it to work on windows it would be great to let me know. Otherwise I am adding a disclaimer section on the readme.

If you clone it instead of pip install : you need to build the C dependencies (used for faster inference) yourself.
You need a C compiler, and there is a makefile in musiclang_predict/c directory, it will build the lib. You can check the setup.py to see what is happening during the setup.

I will work for a more robust setup, but if someone want to give a hand, it would be wonderful !

Thanks for the note Florian. Yes - hoping someone can help out. For reference, I went down the pip install route.
