XLM

XLM demonstrates cross-lingual pretraining with two approaches, unsupervised training on a single language and supervised training on more than one language with a cross-lingual language model objective. The XLM model supports the causal language modeling objective, masked language modeling, and translation language modeling (an extension of the BERT) masked language modeling objective to multiple language inputs).

You can find all the original XLM checkpoints under the Facebook AI community organization.

[!TIP] Click on the XLM models in the right sidebar for more examples of how to apply XLM to different cross-lingual tasks like classification, translation, and question answering.

The example below demonstrates how to predict the <mask> token with [Pipeline], [AutoModel] and from the command line.

from transformers import pipeline


pipeline = pipeline(
    task="fill-mask",
    model="facebook/xlm-roberta-xl",
    device=0
)
pipeline("Bonjour, je suis un modèle <mask>.")

import torch

from transformers import AutoModelForMaskedLM, AutoTokenizer


tokenizer = AutoTokenizer.from_pretrained(
    "FacebookAI/xlm-mlm-en-2048",
)
model = AutoModelForMaskedLM.from_pretrained(
    "FacebookAI/xlm-mlm-en-2048",
    device_map="auto",
)
inputs = tokenizer("Hello, I'm a <mask> model.", return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model(**inputs)
    predictions = outputs.logits.argmax(dim=-1)

predicted_token = tokenizer.decode(predictions[0][inputs["input_ids"][0] == tokenizer.mask_token_id])
print(f"Predicted token: {predicted_token}")
