#conda — Public Fediverse posts

Oof: https://pepy.tech/search?q=snakemake-executor-plugin-slurm

That would be > 500 k via #PyPI and > 100 k via #Conda (got the number with `condastats`)

That, of course, includes all downloads over all versions and including CI usage.

However, there are ~5,000 downloads per relevant version update for Conda alone. This fills me with pride and gives some ammunition for the "for admins" part of my #Snakemake #HPC tutorial. 😉

#SLURM

For the sake of an argument, I wanted to retrieve the cumulative download stats of a package on both Conda and PyPI. Both sites do not display this figure (any more?). For Conda, you now have to download `condastats`. At least, it is easy to use.

For PyPI, there are apparently tools. All of which require getting a token from Google. Seriously?

Does anyone know a straight forward approach to retrieve PyPI download stats over the lifetime of a package?

#Conda #pypi

If you use #tkinter in #conda -managed environment, most likely you will get ugly fonts - the version installed by default lacks freetype support. To fix:

conda install -c conda-forge tk=*=xft_*

New in #Seqera #Containers: you can now edit the #conda environment.yaml directly to control how your container is built. 📦 📄 ✍️

The UI also shows how to do the same with the Wave CLI in your terminal, which also saves to Seqera Containers.

📅 Michigan Python meets TOMORROW (Thursday) at 7pm ET!

I'll be talking about Bridging the conda and PyPI Ecosystems. Come hang out with fellow Pythonistas!

GRASS on Windows via conda: #GRASS, the veteran open-source geospatial computing platform, can now be installed on Windows (and all other major platforms) via #conda with no manual setup. This streamlines access to the latest GRASS functionality.

Now that the keynote is over, here are the open spaces that you can check out after the security update and the first talks after lunch. The job fair and poster sessions are also happening and I would recommend checking those out if you're interested.

Starting at 10:00 AM:

Room 102A: #Conda x #PyPI: Building Bridges That Actually Hold
Room 102B: Scroll Lock Zine
Room 102C: The Python Developers Survey: What Would YOU Ask?
Room 202C: Financial Data with Python

@dan613 It makes sense putting tags up front, but you miss that nice formatting Mastodon does when they're at the end (in the standard web version, at least).

#python #conda #uv

#python #conda #uv

I hadn't updated my development environment in a while, and my package manager (to download and ensure every module has the right dependent modules, if you aren't familiar with Python), Conda, was taking for ev errrrrr!! I had read about a newer manager, uv, written in Rust (the compiled language all the cool kids are talking about), so I figured it was time to try it.

Night and day. I downloaded and configured my entire development environment in about 30 seconds. It uses `pip` commands, though those are rewritten, too. I just gave it a file with a list of mandatory modules and it put in the latest versions, though I could also specify which ones I needed. Super simple.

(I'm trying putting the tags at the beginning of the post to make it easier for people who wouldn't be interested to scroll past. Let me know if this makes it worse for you.)

Software provenance with #Snakemake: Using the reporter plugin for nanopublications, we can now get slightly improved nanopublications like this one: https://w3id.org/np/RAmgzfta63xx0wWc_zzQVm7kwOc4tsEOA0JJJCfsiLL1g (press on the little blue arrow on the right to see the full details). Automatically captured for this workflow: https://w3id.org/np/RAjHDlPDghZzc9ZvQ3uJQNJ9Jd_KAYzZt7dk5PXKgjRyE - again expressed a nanopub declaration. 😉

It now supports to capture the "classic" software support for #Conda and Snakemake wrappers.

There is more work to do. Let's see when and if I get to it.

@millihertz what #Python really needs is a way to distribute pre-build #conda environments without using flatpak or docker or the like. Yes, you can send an env file and make people download everything themselves, but I'm thinking pre-packaged "this is all the stuff in my environment for this package" as a ZIP type blob that acts as conda environment to the app.
ymmv.

#gnuradio

On #macos #tahoe installed with #conda, I'm going slightly insane.

gnuradio (v3.10.12.0) depends on qt-main (v5.15.15)

gnuradio also depends on qwt (v6.3.0) which depends on qt6-main (v6.10.1)

So, now I have both qt5 and qt6 installed .. by the installer .. that fails when you attempt to run anything because there's two versions of qt installed.

Anyone?

I finished the basic #tutorial for #snakemake and it really fits my vibe right now, hehe
Also learned a bit more about #conda along the way. I'll take that

How sharded repodata (CEP-16) makes conda and Pixi 10x faster with 90% less bandwidth on conda-forge.

#PackageManagement #OpenSource #Python #Conda #Pixi #DataScience

Last week I was a little annoyed about missing Microsoft C++ Build Tools #MSVC on a system without admin rights. I needed a compiler for building the #python C++ extension I developed a while ago. Annoyed not because I could not ask someone to install it for me, but annoyed because of the lack of compiler choices in this particular case. I have to use the MSVC instead of let's say #g++ which I could easily install via the #MinGW-w64 #conda package myself.

I found out that I can tell #setuptools (the backend build system) via #pip config settings to use a different compiler during build:

I am really enjoying the Pixi package manager, https://pixi.sh , made by @prefix. We have been using conda at my work for managing the dependencies of our python application. It involves scientific data analysis so there are lots of dependencies, and it has been a challenge to keep things up to date. Pixi has nice support for cleanly defining the direct dependencies in the pixi.toml file, and then it automatically generates a lock file. There is a command to upgrade all the dependencies too. It's amazing! I'm just starting to use it, but it is helpful so far.

Last week I was in Málaga with the @conda OSS team (Anaconda + Quansight).

Aligned on vision and roadmap. Had real talk about code review anxiety and supporting each other better as a distributed team.

Sprint day highlight: shipped progress on wheels support and sharded repodata. Nothing beats building together in person.

Excited for 2026 🚀

Today I learned that the conda package manager for python supports preprocessing selectors in its environment yaml files to add/delete lines for certain platforms.

A prime example is the installation of pytorch via the following environment.yml:
```
dependencies:
- python
- pip
- pip:
- --index-url https://download.pytorch.org/whl/cu128 # [win] # Only relevant for Windows systems
- --extra-index-url https://pypi.org/simple # [win]
```

This will use the pytorch package index on Windows but use PyPi on all other systems.
