I installed version 23.04.0 of MOA. I follow the "https://github.com/opencollab/arpack-ng" tutorial to install arpack-ng through MSYS2 with the command "pacman -S mingw-w64-x86_64-arpack", and then the system generates libarpack.a and libarpack.dll, etc. document. When I run massive online analysis, I get an error "Failed to load implementation from: com.github.fommil.netlib.NativeSystemARPACK".What should I do?

I have defined environment variables "D:\msys64\mingw64\bin" and "D:\msys64\mingw64\opt\bin".

Hi, in case your code does not rely on ARPACK functionality you can continue to use MOA even if it fails to load it. In case you really need it, then the best option is to look for what solutions are available in the WEKA realm because not many people use ARPACK in MOA, so it will be hard to find help
