@jeremyphoward @pablovelagomez1 @prefix_dev Pixi has been great and will hopefully support a conda like workflow soon (global registery of envs). I have a simple bash function that I use as a proxy until that PR gets merged

@pablovelagomez1 @prefix_dev Oh yeah I forgot about pixi! How come no one talks about pixi?...

For folks that don't use conda, how do you debug problems that only occur on some particular Python or CUDA version? With conda, I have a few envs set up with various python and CUDA versions, so I just activate one and get to work. With something like uv, what do you do?

I'm taking a break from this site. Come find me over at bsky under the same handle

@HEPfeickert No problem. There was definitely some anxiety involved in putting out (and promoting) code that had issues, so I wanted to get it fixed asap. I'm still not sure why I never ran into an issue with this using mamba for several different complicated projects on both macos and linux

@synapticarbors @abkfenris Wow! Thank you for being amazingly fast and fixing that! github.com/prefix-dev/pix…

pixi 0.30.0 is now available! In this release I contributed `pixi project export conda-explicit-spec` that allows you to export a pixi.lock file to a conda explicit spec that can be used with conda/mamba. Full release notes are here github.com/prefix-dev/pix… @prefix_dev

pixi now also supports exporting a conda environment.yml as well thanks to @abkfenris, and I am working on functionality for exporting pip/uv requirements.txt for pypi dependencies.

I'm particularly excited about this since it allows you to manage environments using pixi and then deploy to conda/mamba. This replaces conda-lock for me and has the benefit of using pixi's more expressive pixi.toml format to specify envs in place of an environment.yml.

Numba continues to be a quiet but powerful tool in the Python high-performance arsenal.

@williamfalcon LitServe is now available for conda/mamba via conda-forge.

For years we've wanted to build the "PyTorch Lightning" for model serving... announcing LitServe 🚀🚀🚀 Check it out and let us know what you think! ✅ 2x faster than FastAPI ✅ GPU autoscaling ✅ LLMs, NLP, vision ✅ PyTorch, SkLearn, Jax... ✅ ... 10+ more features Github: github.com/Lightning-AI/l… Huge team effort! 💜💜💜

@vsbuffalo It's mentioned in that thread, but conda-forge is not bound by the same ToS. See also prefix.dev/blog/towards_a…

Yea, compbio folks beware: Anaconda is now trying to get academic users to pay licensing fees. See this Reddit thread too: reddit.com/r/bioinformati…

I'm going to be at @pycon 2024 in Pittsburgh and am looking forward to seeing some online faces in person. I'm local and will be at the convention all day Friday and partial days on Saturday and Sunday. Please reach out if you're going to be here and want to chat #PyCon #PyConUS

PyData Pittsburgh @PyDataPGH has a call for proposals for future events: pypgh.org/call-for-propo…

@Mailia Another tool that tries to give a "cargo for python" experience is pixi.sh from @prefix_dev. It would certainly solve your uWSGI issue since it can pull from conda channels that distribute pre-built binaries.

I tried out Rye (the Python tool) and wrote some of my thoughts on it and Python tooling in general. burakku.com/blog/rye-test-…

We wrote a blog about our multiple environment support! It completely redefines the use of test and production environments with solve-groups. ✨ Introducing pixi's multiple environments #rustlang #package #management #conda #Python #SoftwareEngineering

One place where it really shines is the ability to download and manage global tools. It has completely replaced condax/pipx for me.

I've started experimenting with using pixi from @prefix_dev as a conda/mamba replacement. I'm not sold yet on the directory-based workflow (compared with a global registry of envs), but I'm hoping a future release allow for more flexibility.

Want to see WE / WESTPA applied towards understanding the free-energy landscape of phase separation in lipid bilayers? Check it out:

@curiouswavefn I took p-chem at Haverford with Julio de Paula using the 6th edition. I believe we were the guinea pigs for some of the material that went into the next edition when Julio joined as co-author. It was a great class and he was really an outstanding teacher.

Had forgotten what a pleasure it is to read Atkins; the man has always been a pedagogical master.

conda-lock has made environment management so much easier. Now I just create a unified conda-lock across all platforms, then render to a specific platform so that others can just use `conda/mamba create -n newenv --file conda-<platform>.lock`, without needing conda-lock

Is anyone using micromamba as a complete conda/mamba replacement for everyday development (rather than just in CI)?
