Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Candle: Torch Replacement in Rust
I am so happy about them releasing this. A few years ago I wrote a multi-task syntax annotator in Rust using Laurent Mazare's excellent tch-rs binding (it seems like he is also working on Candle):
https://github.com/tensordot/syntaxdot
However, the deployment story was always quite difficult. The PyTorch C++ API is not stable, so a particular version of tch-rs will only work with a particular PyTorch version. So, anyone wanting to use SyntaxDot always had to get exactly the right version of libtorch (and set some environment variables) to build the project.
The idea of making an abstraction over Torch and Rust ndarray (similar to Burn) crossed my mind several times, but there is only so much that I could do as a solo developer. So Candle would be a god-given if I was still working on this project.
Seeing Candle wants to make me port curated-transformers to Candle for fun:

Ask HN: What is the job market like, for niche languages (Nim, crystal)?
They are obviously not as good as in Python, but if you are willing to invest time, it's definitely doable. E.g. I made a multi-task transformer-based syntax annotator in Rust using the tch Torch binding:
https://github.com/tensordot/syntaxdot
In my current job, I do NLP with Python, Cython, and some C++. I don't think doing it in Rust was much more work. Once you are beyond the stage of implementing a small research project or toy model, most systems are going to contain a lot of custom, specialized code. You will have to do that work in any language.

PyTorch 1.8 release with AMD ROCm support
What I like about PyTorch is that most of the functionality is actually available through the C++ API as well, which has 'beta API stability' as they call it. So, there are good bindings for some other languages as well. E.g., I have been using the Rust bindings in a larger project [1], and they have been awesome. A precursor to the project was implemented using Tensorflow, which was a world of pain.
Even things like mixed-precision training are fairly easy to do through the API.

SpaCy v3.0 Released (Python Natural Language Processing)
Huggingface fills the need for task based prediction when you have a GPU.
With model distillation, it should be possible to annotate hundreds of sentences per second on a single CPU with a library like Huggingface Transformers.
For instance, one of my distilled Dutch multi-task syntax models (UD POS, language-specific POS, lemmatization, morphology, dependency parsing) annotates 316 sentences per second with 4 threads on a Ryzen 3700X. This distilled model has virtually no loss in accuracy, compared to the finetuned XLM-RoBERTa base model.
I don't use Huggingface Transformers, but ported some of their implementations to Rust [1], but that should not make a big difference since all the heavy lifting happens in C++ in libtorch anyway.
tl;dr: it is not true that tranformers are only useful for GPU prediction. You can get high CPU prediction speeds with some tricks (distillation, length-based bucketing in batches, etc.).

Ask HN: What Happened to TensorFlow Swift
lattner left google and was the primary reason they chose swift, so they lost interest.
if you're asking from an ML perspective, i believe the original motivation was to incorporate automatic differentiation in the swift compiler. i believe enzyme is the spiritual successor.

For the auto-differentiation when I need performance or memory, I currently use tapenade ( http://tapenade.inria.fr:8080/tapenade/index.jsp ) and/or manually written gradient when I need to fuse some kernel, but Enzyme ( https://enzyme.mit.edu/ ) is also very promising.

Do you consider making a physics engine (for RL) worth it?
For autodiff, we are currently working again on publishing a new Enzyme (https://enzyme.mit.edu) Frontend for Rust which can also handle pure Rust types, first version should be done in ~ a week.

The Julia language has a number of correctness flaws
Enzyme dev here, so take everything I say as being a bit biased:
While, by design Enzyme is able to run very fast by operating within the compiler (see https://proceedings.neurips.cc/paper/2020/file/9332c513ef44b... for details) -- it aggressively prioritizes correctness. Of course that doesn't mean that there aren't bugs (we're only human and its a large codebase [https://github.com/EnzymeAD/Enzyme], especially if you're trying out newly-added features).
Notably, this is where the current rough edges for Julia users are -- Enzyme will throw an error saying it couldn't prove correctness, rather than running (there is a flag for "making a best guess, but that's off by default"). The exception to this is garbage collection, for which you can either run a static analysis, or stick to the "officially supported" subset of Julia that Enzyme specifies.
Incidentally, this is also where being a cross-language tool is really nice -- namely we can see edge cases/bug reports from any LLVM-based language (C/C++, Fortran, Swift, Rust, Python, Julia, etc). So far the biggest code we've handled (and verified correctness for) was O(1million) lines of LLVM from some C++ template hell.
I will also add that while I absolutely love (and will do everything I can to support) Enzyme being used throughout arbitrary Julia code: in addition to exposing a nice user-facing interface for custom rules in the Enzyme Julia bindings like Chris mentioned, some Julia-specific features (such as full garbage collection support) also need handling in Enzyme.jl, before Enzyme can be considered an "all Julia AD" framework. We are of course working on all of these things (and the more the merrier), but there's only a finite amount of time in the day. [^]
[^] Incidentally, this is in contrast to say C++/Fortran/Swift/etc, where Enzyme has much closer to whole-language coverage than Julia -- this isn't anything against GC/Julia/etc, but we just have things on our todo list.
