CvT-21

Wu et al., 2021 — CvT: Introducing Convolutions to Vision Transformers (arXiv:2103.15808)

Lucid port of transformers/microsoft/cvt-21, converted to Lucid-native safetensors.

Available weights

Tag	acc@1	acc@5	Params	GFLOPs	Size	Source
IN1K (default)	82.5	—	31.6M	—	120.87 MB	transformers

Usage

import lucid.models as models
from lucid.models.weights import CvT21Weights

# default tag
model = models.cvt_21_cls(pretrained=True)

# explicit tag (enum or string)
model = models.cvt_21_cls(weights=CvT21Weights.IN1K)
model = models.cvt_21_cls(pretrained="IN1K")

# preprocessing travels with the weights
weights = CvT21Weights.IN1K
preprocess = weights.transforms()
logits = model(preprocess(image)[None]).logits

Conversion

Converted from transformers/microsoft/cvt-21 via python -m tools.convert_weights cvt_21 --tag IN1K. Key mapping + numerical parity verified against the source.
