# 🤗 Transformers

Machine Learning allo stato dell'arte per PyTorch, TensorFlow e JAX.

🤗 Transformers fornisce delle API per scaricare in modo semplice e allenare modelli pre-allenati allo stato dell'arte. L'utilizzo di modelli pre-allenati può ridurre i tuoi costi computazionali, l'impatto ambientale, e farti risparmiare il tempo che utilizzeresti per allenare un modello da zero. I modelli possono essere utilizzati in diverse modalità come ad esempio:

* 📝 Testo: classificazione del testo, estrazione delle informazioni, rispondere a domande, riassumere, traduzione e generazione del testo in più di 100 lingue.
* 🖼️ Immagini: classificazione di immagini, rilevazione di oggetti e segmentazione.
* 🗣️ Audio: riconoscimento vocale e classificazione dell'audio.
* 🐙 Multimodale: rispondere a domande inerenti dati tabulari, riconoscimento ottico dei caratteri, estrazione di informazioni a partire da documenti scannerizzati, classificazione di video e risposta visuale a domande.

La nostra libreria supporta un'integrazione perfetta tra tre delle librerie per il deep learning più popolari: [PyTorch](https://pytorch.org/), [TensorFlow](https://www.tensorflow.org/) e [JAX](https://jax.readthedocs.io/en/latest/). Allena il tuo modello in tre righe di codice in un framework, e caricalo per l'inferenza in un altro.

Ogni architettura di 🤗 Transformers è definita in un modulo Python indipendente così da poter essere personalizzata in modo semplice per la ricerca e gli esperimenti.

## Contenuti

La documentazione è organizzata in cinque parti:

- **INIZIARE** contiene un tour rapido e le istruzioni di installazione per cominciare ad utilizzare 🤗 Transformers.
- **TUTORIALS** è un buon posto da cui iniziare se per te la nostra libreria è nuova. Questa sezione ti aiuterà ad acquisire le competenze basilari di cui hai bisogno per iniziare ad  utilizzare 🤗 Transformers.
- **GUIDE PRATICHE** ti mostrerà come raggiungere obiettivi specifici come fare fine-tuning di un modello pre-allenato per la modellizzazione del linguaggio o come creare una testa per un modello personalizzato.
- **GUIDE CONCETTUALI** fornisce discussioni e spiegazioni dei concetti sottostanti alle idee dietro ai modelli, compiti, e la filosofia di progettazione di 🤗 Transformers.
- **API** descrive ogni classe e funzione, raggruppate in:
    - **CLASSI PRINCIPALI** per le classi principali che espongono le API importanti della libreria.
    - **MODELLI** per le classi e le funzioni relative ad ogni modello implementato all'interno della libreria.
    - **HELPERS INTERNI** per le classi e le funzioni che utilizziamo internamente.

La libreria attualmente contiene implementazioni in JAX, PyTorch e TensorFlow, pesi di modelli pre-allenati, script di utilizzo e strumenti di conversione per i seguenti modelli.
