We're building the fast, deterministic and reproducible package manager Pixi for scientific and robotics workflows. Based on @condaforge & @robostack packages.

The Pixi team is at ROSCON in Toronto - come find the yellow backpacks if you want to chat! We keep spotting Pixi in so many cool robotics projects and it's making us proud. To get a glimpse of what we're working on, join the talk about the EU CRA this afternoon!

NVIDIA Isaac ROS 5.0 brings AI agents to robotics development. 🤖
Announced at #ROSCon, the release adds agentic workflows, Isaac Skills, ROS 2 Lyrical support, GPU-accelerated libraries and NVIDIA Jetson support from Orin Nano to Thor.
Open source and available now 📖 nvda.ws/3VahoaA
If you see one of these people #ROSCON, they are likely from prefix.dev! Come say hi, we're friendly! 💛
@OpenRoboticsOrg
We made it easy to install Isaac ROS! The new `isaac-forge` repository contains many upstream NVIDIA Isaac ROS packages to make them installable with Pixi. You can test it today on your #NIVIDA #Jetson!
No docker needed!

Congratulations to the Mojo 1.0 release @Modular! So glad to have you in our community, and seeing @clattner_llvm on stage with `pixi` in the background was definitely a highlight for us.
playground.rattler.build got a redesign and a recipe generator for PyPI, CRAN and CPAN.
Paste a package name, get a recipe.yaml back.
rattler-build now builds for iOS and Android.
Conda packages on mobile. Yes, really, we're picking up an old idea from the "conda-mobile" project.
pixi update --offline now resolves against only what you already have: the package cache and local file:// channels.
Air-gapped machines, planes, CI without egress.
Pixi now fully supports archspec, so you can create CPU-optimized environments and let Pixi handle the installation logic.
Read more about it in the blogpost we updated:
prefix.dev/blog/building_cpu…
Use pixi global to install any project from source now.
Pixi global supports the full package spec to configure the neccesary information to install it directly, without a pixi.toml.
Building a git repo that never heard of Pixi used to mean forking it.
Now you declare the build backend inline and Pixi builds it from source.
Conda packages can have extras now.
Optional dependency groups you declare and then consume, via v3 repodata. Plus when conditions and variant flags.
This should also be available on conda-forge in the near future!
📖 : pixi.prefix.dev/latest/conce…
No more gpu and cpu environments, let pixi choose the right platform for you!
[system-requirements] is deprecated. Platforms now carry the requirements themselves.
CUDA and glibc constraints inline, and you can name a target what you actually call it.

Don't forget to join the RoboStack Community Meeting today!

Lastly, I'm a contributor to the `pixi-build-mojo` backend, which is what @prefix_dev can use to build Mojo projects: pixi.prefix.dev/latest/build…
And allows you to install dependencies directly from GitHub, which is really cool!
PEP 723 only covers Python and PyPI, so Pixi reads tool.pixi for the rest.
Which means conda dependencies in a standalone script.
A single Python file can now carry its own environment.
pixi run --script hello.py
Pixi reads PEP 723 inline metadata.
