Could not find module 'libdmtx-32.dll'

[SablyTv]

Im trying to import decode from pylibdmtx by:

from pylibdmtx.pylibdmtx import decode

but get this error:

Traceback (most recent call last): File "C:\Users\Administrator\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pylibdmtx\dmtx_library.py", line 38, in load libdmtx = cdll.LoadLibrary(fname) File "C:\Users\Administrator\AppData\Local\Programs\Python\Python38-32\lib\ctypes__init__.py", line 451, in LoadLibrary return self._dlltype(name) File "C:\Users\Administrator\AppData\Local\Programs\Python\Python38-32\lib\ctypes__init.py", line 373, in init__ self._handle = _dlopen(self._name, mode) FileNotFoundError: Could not find module 'libdmtx-32.dll' (or one of its dependencies). Try using the full path with constructor syntax.

During handling of the above exception, another exception occurred:

Basically even though the file is there, on python 3.8+ the dll directory has to be declared.

I resolved this issue by following this:

Windows error message If you see an ugly ImportError when importing pylibdmtx on Windows you will most likely need the Visual C++ Redistributable Packages for Visual Studio 2013. Install vcredist_x64.exe if using 64-bit Python, vcredist_x86.exe if using 32-bit Python.
