Posit AI Weblog: Hugging Face Integrations



We’re completely happy to announce the primary releases of hfhub and tok are actually on CRAN.
hfhub is an R interface to Hugging Face Hub, permitting customers to obtain and cache information
from Hugging Face Hub whereas tok implements R bindings for the Hugging Face tokenizers
library.

Hugging Face quickly grew to become the platform to construct, share and collaborate on
deep studying purposes and we hope these integrations will assist R customers to
get began utilizing Hugging Face instruments in addition to constructing novel purposes.

We even have beforehand introduced the safetensors
bundle permitting to learn and write information within the safetensors format.

hfhub

hfhub is an R interface to the Hugging Face Hub. hfhub at present implements a single
performance: downloading information from Hub repositories. Mannequin Hub repositories are
primarily used to retailer pre-trained mannequin weights along with every other metadata
essential to load the mannequin, such because the hyperparameters configurations and the
tokenizer vocabulary.

Downloaded information are ached utilizing the identical structure because the Python library, thus cached
information will be shared between the R and Python implementation, for simpler and faster
switching between languages.

We already use hfhub within the minhub bundle and
within the ‘GPT-2 from scratch with torch’ weblog submit to
obtain pre-trained weights from Hugging Face Hub.

You should use hub_download() to obtain any file from a Hugging Face Hub repository
by specifying the repository id and the trail to file that you simply wish to obtain.
If the file is already within the cache, then the operate returns the file path imediately,
in any other case the file is downloaded, cached after which the entry path is returned.

weblog submit ‘What are Massive Language Fashions? What are they not?’.

When utilizing a pre-trained mannequin (each for inference or for positive tuning) it’s very
vital that you simply use the very same tokenization course of that has been used throughout
coaching, and the Hugging Face staff has carried out an incredible job ensuring that its algorithms
match the tokenization methods used most LLM’s.

tok supplies R bindings to the 🤗 tokenizers library. The tokenizers library is itself
carried out in Rust for efficiency and our bindings use the extendr mission
to assist interfacing with R. Utilizing tok we are able to tokenize textual content the very same method most
NLP fashions do, making it simpler to load pre-trained fashions in R in addition to sharing
our fashions with the broader NLP group.

tok will be put in from CRAN, and at present it’s utilization is restricted to loading
tokenizers vocabularies from information. For instance, you possibly can load the tokenizer for the GPT2
mannequin with:

Bear in mind that you could already host
Shiny (for R and Python) on Hugging Face Areas. For example, we now have constructed a Shiny
app that makes use of:

  • torch to implement GPT-NeoX (the neural community structure of StableLM – the mannequin used for chatting)
  • hfhub to obtain and cache pre-trained weights from the StableLM repository
  • tok to tokenize and pre-process textual content as enter for the torch mannequin. tok additionally makes use of hfhub to obtain the tokenizer’s vocabulary.

The app is hosted at on this Area.
It at present runs on CPU, however you possibly can simply change the the Docker picture if you need
to run it on a GPU for sooner inference.

The app supply code can also be open-source and will be discovered within the Areas file tab.

Trying ahead

It’s the very early days of hfhub and tok and there’s nonetheless a whole lot of work to do
and performance to implement. We hope to get group assist to prioritize work,
thus, if there’s a function that you’re lacking, please open a problem within the
GitHub repositories.
