@graalvm Fixed already for the next release 😊 github.com/oracle/graalpy…

There's always more compatibility issues to fix in GraalPy, and it's cool use-cases like this that help us prioritise: github.com/msievers/graal… Let us know about yours! #graalpy @graalvm

@maxandersen @jbangdev @graalvm Sure, I didn't initially put it anywhere, but you prompted me to clean it up a bit so it's a reasonable usage example :) github.com/timfel/adfexpl…

@timfelgentreff @jbangdev @graalvm Cool. Can you share the source ?

I wanted a small tool to graphically manage ADF disk images. There's a Python library to work with them on the commandline. Whipped up a quick Java UI with @jbangdev using the #graalpy template and got myself a standalone native app thanks to @graalvm native image :)

We run the tests of ~600 PyPI packages every day to catch #GraalPy regressions and generate compatibility tickets for ourselves - a lot of stuff "just works" these days and we're working hard to match CPython: #why-graalpy" target="_blank" rel="nofollow noopener">github.com/oracle/graalpy… #graalvm

@eatonphil @thomaswue Yes, CPython is using the Cython code compiled to a native extension. If CPython runs the same Python code as GraalPy or PyPy, I get 13fps for this demo

@timfelgentreff @thomaswue The CPython numbers (243fps) I assume means CPython with parts of it are Cython?

Years ago github.com/Baekalfen/PyBoy had to rewrite code to Cython to provide enough performance on CPython. Today, GraalPy can JIT the pure Python to within a few percent of the natively compiled Cython code (demo Gejmbåj by Snorpung) #graalvm #graalpy

@dainius_jocas @thomaswue @graalvm Yes, we don't strip the Python parts of the image at all, so even for a "Hello World" the image includes the entire Python language core, tooling, Python standard library and JIT infrastructure code. Definitely something we are looking into improving!

@thomaswue @graalvm Awesome! But it took 7 minutes to compile hello world on M3 cpu and the binary is 280 MB

@johan_tlb @thomaswue @graalvm Yep, seems to work with that mentioned package, too

@johan_tlb @thomaswue @graalvm Yes, there's a venv argument to the command @thomaswue posted, the venv is automatically included into the binary. See e.g. #tweaked-to-work-with-graalpy-standalone" target="_blank" rel="nofollow noopener">github.com/timfel/racing-… for an example

Want to quickly call some Python code from your Java tool? Thanks to @maxandersen's help, you can now do it with @jbangdev, too. Also works with @GraalVM Native Image :) #graalpy #graalvm ➡️github.com/timfel/graalpy…

Time for some lightning⚡Single, self-contained binary running a PyGame racer github.com/timfel/racing-… github.com/oracle/graalpy… #graalpy #graalvm

How do other people deploy their pygames? With GraalPy 23.1, it can all be in single binary file, ready to run. Try "graalpy -m standalone --help" #graalpy #graalvm

@fwbrasil @grashalm_ Getting there, PyTorch works well (>80% of their tests passing), the latest Tensorflow has started running a wee bit too late for this release. Both that and some cool Java integration features will land in master very soon and go into the next release :)

@grashalm_ congrats! How mature is the python support nowadays? It'd be great to use some LLM-related python libs on the JVM

GraalVM for JDK 21/Polyglot 23.1 just landed! 🤩 GU is dead! You can now use all languages from Maven Central without barriers. This is such a big change that we felt the need to justify it with a blog post: medium.com/graalvm/truffl…

@rkh_popcorn Bit late, but if you want to feel even better: asofterworld.com/index.php?id=1…
