Usage
import lucid
import lucid.models as models
from lucid.models.weights import GPT2LargeWeights
# default tag
model = models.gpt2_large(pretrained=True)
# explicit tag (enum or string)
model = models.gpt2_large(weights=GPT2LargeWeights.WEBTEXT)
model = models.gpt2_large(pretrained="WEBTEXT")
# 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/gpt2-large via
