No module named 'mlpack.image_converter' during import in python at Mac. about mlpack HOT 6 CLOSED

I released mlpack 4.3.0.post2 to PyPI (it took a long time to rebuild all the wheels!) and these should all have image_converter included now. Thanks for the report @eptitsyn!

Hello @eptitsyn
I am here to offer assistance.
Please consider the following these steps
Just make sure folder also contains an init.py, this allows it to be included as a package.
Not sure why the other answers talk about PYTHONPATH.

That answer is not correct. I believe that the mlpack package posted on PyPI had a build error where STB was not found and resultantly the image converter functionality was not included, but I think this is only true for the macOS builds. I wanted to look into this and post with a solution and say "the package is updated!" but I have not had a chance yet.

There was still just one more thing to do, which was backport that fix to PyPI and get a new version uploaded. I've been working on this, and I'm just about there, but the mlpack-wheels builds take forever so it's been a slow iteration process to ensure image_converter gets built correctly, etc... Hopefully this should be done within a week, most of the time is just waiting.
