RoFormer (Chinese base)

https://arxiv.org/abs/2104.09864

Lucid port of transformers/junnyu/roformer_chinese_base, converted to Lucid-native safetensors.

Available weights

Usage

import lucid
import lucid.models as models
from lucid.models.weights import RoformerWeights

# default tag
model = models.roformer(pretrained=True)

# explicit tag (enum or string)
model = models.roformer(weights=RoformerWeights.CLUECORPUSSMALL)
model = models.roformer(pretrained="CLUECORPUSSMALL")

# feed token ids (tokenize with the matching lucid.utils.tokenizer)
input_ids = lucid.tensor([[101, 7592, 2088, 102]], dtype=lucid.int64)
out = model(input_ids)
hidden = out.last_hidden_state  # (B, T, hidden_size)

Conversion

Converted from transformers/junnyu/roformer_chinese_base via python -m tools.convert_weights roformer --tag CLUECORPUSSMALL. Key mapping + numerical parity verified against the source.
