Python opcodes no longer working on Windows..

[rorywalsh]

I'm just posting this here to remind me to investigate the issue when I have a chance, but after building a new version with the latest build of csound I get an error when trying pyinit:

Fatal Python error: Py_Initialize: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'

When I prepared binaries for Windows in Aug 2021 these opcodes worked. I am using the same toolchain to build now as I did then, and I haven't changed or updated Python since. Anyone have ideas where I should start looking?

It could be a problem with the Python installation. It's working on MacOS, I tried the binaries from the installer yesterday using a universal build of Csound (beta 6.18) and CsoundQT (x86_64) on a Mac M1 and it runs correctly.

Could be, but Python3 is running fine on my machine, CMake finds it without any issues. I'm hesitant to mess with my Python install as it took me some time to get it working with all the various libraries I need. I'm happy to help another Windows user try to get them working on their PC.

Hi! I made a built of the python opcode on a windows 11 machine. The built went through. But when I try to start it from within the commandline or CsoundQT i get the following messages:

CSOUNDQT:

Perhaps you're building for x86 instead of x64? Can you open the MSVC .sln and make sure you have x64 selecting in the configuration panel?

@rorywalsh sorry for the late response. Yeah built it with debug x64 in visual studio 2022. Py opcode still not working
