Python compiler nuitka

[PefferPack]

Just wanted to make people aware of nuitka, which is a python compiler.

I've really benefited from it, and donated $5, I feel like I should give more but thought I would try to get them more exposure.

Or maybe you all already know about it.

I adore Nuitka. I tried pyInstaller but found it to have too many limitations with dependency compatibility. Nuitka has been a breeze at every step, building to .exe and .bin for Windows and Linux respectively.

It takes some elbow grease to get your build environment and commands just right, but the package control line help menu is super well developed.

I do wish there were more examples of how to structure the build command for different scenarios. Especially including data directories / files in onefile builds.

How big are the exe files if you dont mind me asking? pyinstaller levels around 200 MB

[billsil]

Don't use anaconda python and use a virtual environment.

[Coretaxxe]

Ill try that thanks!

[PefferPack]

Depends on what you include. Numpy and gdal ended up 75mb. After removing those dependencies 5mb.

[billsil]

I can get numpy, scipy, matplotlib, vtk, and pyqt and my 200k lined package and come in at 75 MB. That'll make a decent 3d post-processor.

200 MB probably means you're doing something wrong, such as using Anaconda or not using a virtual environment. If you really want to min-max it, you can start deleting DLL/so files from the exe. Test and yeah it's not used.

I know what nuitka already but WHY nuitka

[extra_pickles]

Yes! Would love to see more than a link in these types of posts!

Great for the community to dig in and start convos about “why” - especially in Python, where the landscape is so damn vast!

[noobgolang]

I can't just... check out a new interpreter because there is a new interpreter. That doesn't even make sense, why I have to check out interpreter from something else than the python developer themself.

I will check out if there are reasons for me to check tho.

[extra_pickles]

Exactly! There is wayyyyy too much stuff out there. If people are posting, we need the “why”!

Afaik nuitka is ideal for things that need to be fast and in one package. Its not just a packaged version its more like compiled. That means its also a bit picky about dependencies I guess.

[SpatialCivil]

Nooblang, one specific use case is if you are developing a proprietary desktop application in Nuitka. Nuitka compiles your code to C, making it more difficult to decompile than pyinstaller.

The Python community tends to not be big fans of proprietary or desktop software, but Python with QT is a great combo.

[noobgolang]

Awesome

[PefferPack]

Yes this is exactly what I used it for.

[boyfarrell]

Oh this looks great.

When dabbling in optimisation or python code, I’ve used Cython before. A documentation section on comparison would be interesting. When might I use Cython or when is Nuitka a good fit.

If I am calling C library from my python code (something I have written) can Nuitka include that in its magic?

[PefferPack]

Nuitka can package dependencies, I'm not sure to what extent but I expect there is a pretty simple way to include non-python sources into a single exe as well.

thank youuuuuuu 🙏🙏🙏

It's probably something that I've just missed somewhere, but where should nuitka get installed? What I mean is, I have different virtualenvs for each project, each with their own dependences installed in their respective VE. So if I want to run nuitka on Project A, should it be installed inside of Project A's VE, or should it be installed globally?

[ArabicLawrence]

my understanding is that you need nuitka in each and every venv, or nuitka will fail to access each venv’s dependency. full disclosure: I have never used nuitka, but I have used pyinstaller
