twitter-xlm-roberta-base-sentiment-fast
This is an exact copy of cardiffnlp/twitter-xlm-roberta-base-sentiment with one addition: a prebuilt tokenizer.json.
Why this exists
The original repository ships only a SentencePiece tokenizer (sentencepiece.bpe.model) and no tokenizer.json. On transformers v5, loading the tokenizer forces an on-the-fly SentencePiece → fast conversion, which currently fails for XLM-RoBERTa and raises:
ValueError: Error parsing line b'\x0e' in .../sentencepiece.bpe.model
(or, on some late 4.x releases, AttributeError: 'NoneType' object has no attribute 'endswith' from the tekken.json conversion branch).
This copy includes a tokenizer.json generated with transformers 4.44.2, so v5 loads the tokenizer directly and never runs the broken conversion. The tokenizer is verified to produce identical token ids to the original slow tokenizer.
The model weights are byte-for-byte the same as the original.
Usage
from transformers import pipeline
clf = pipeline(
task="sentiment-analysis",
model="NetworkIsLife/twitter-xlm-roberta-base-sentiment-fast",
tokenizer="NetworkIsLife/twitter-xlm-roberta-base-sentiment-fast",
)
clf("T'estimo!")
# [{'label': 'Positive', 'score': 0.66...}]
Or load the pieces directly:
from transformers import AutoTokenizer, AutoModelForSequenceClassification
repo = "NetworkIsLife/twitter-xlm-roberta-base-sentiment-fast"
tok = AutoTokenizer.from_pretrained(repo)
mdl = AutoModelForSequenceClassification.from_pretrained(repo)
