BERT-Mini

https://arxiv.org/abs/1810.04805

Lucid port of transformers/google/bert_uncased_L-4_H-256_A-4, converted to Lucid-native safetensors.

Available weights

Tag	Params	GFLOPs	Size	Source
`WIKIPEDIA_BOOKSCORPUS` (default)	11.2M	—	42.62 MB	transformers

Usage

import lucid
import lucid.models as models
from lucid.models.weights import BertMiniWeights

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

# explicit tag (enum or string)
model = models.bert_mini(weights=BertMiniWeights.WIKIPEDIA_BOOKSCORPUS)
model = models.bert_mini(pretrained="WIKIPEDIA_BOOKSCORPUS")

# 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/google/bert_uncased_L-4_H-256_A-4 via python -m tools.convert_weights bert_mini --tag WIKIPEDIA_BOOKSCORPUS. Key mapping + numerical parity verified against the source.
