opencv + python3.12 fails on "ModuleNotFoundError: No module named 'imp'" about nuitka HOT 11 OPEN

I tested it, the test script works for me, too! Thanks

Are you sure your program is running with Python3.12, since there is no imp module.

from nuitka.

Ah, it's probably these things:

      replacements:
        "load_first_config(['config.py'], True)": "textwrap.indent(pkgutil.get_data('cv2', 'config.py').decode('utf8'), '    ') + textwrap.indent(pkgutil.get_data('cv2', 'config-3.py').decode('utf8'), '    ')"
        # Before OpenCV 4.6
        'native_module = importlib.import_module("cv2.cv2")': '"import imp; native_module = imp.load_dynamic(\"cv2\", os.path.join(os.path.dirname(__file__), \"cv2%s\"))" % getSharedLibrarySuffix(False)'
        # After OpenCV 4.6
        'native_module = importlib.import_module("cv2")': '"import imp; native_module = imp.load_dynamic(\"cv2\", os.path.join(os.path.dirname(__file__), \"cv2%s\"))" % getSharedLibrarySuffix(False)'

These could be changed to use _imp I suppose.

Thanks for your report, this is fixed on the factory branch, which is a development version under rapid development. You can try it out by going here: https://nuitka.net/doc/factory.html

Feedback on whether this is working is very welcome. Please do not share plans to do it; only confirm or deny that it is working.

Let me know if it works, I only changed the code, expecting everything else to be fine now.

from nuitka.

I tried it, it seems to have fixed the initial error, but now the error changed to this one

Too bad, I think I saw it on older versions, wasn't expecting it to not be there.

from nuitka.

So, in the tests of CPython 3.12, they copied the code of load_dynamic from the former imp module, which would be one way of doing it, and probably what we have to do. I will give it a shot, if anything is needed at all there, maybe for 4.6+ it is now needed at all, and we continued doing it.

from nuitka.

Unfortunately the workaround is still needed though.

from nuitka.

I devised a manual load with ExtensionFileLoader just as done in the 3.12 test suite, for which there seems to be no function in proper Python anymore. Manual module loading is going to spread like wildfire, and people barely get those things correct, but what do I know, slightly annoyed here.

from nuitka.

So right now factory is actually working.
