ConViT
Category: ViT · Code: timm/models/convit.py · Architectures: 3 · Pretrained weights: 3 (3 with ImageNet-1k results)
ConViT replaces the self-attention of the early Vision Transformer blocks with gated positional self-attention (GPSA), which can be initialized to behave like a convolution, as a soft convolutional inductive bias.

Usage
See the Quickstart for loading pretrained weights, image preprocessing and fine-tuning, and Feature Extraction for using the models as backbones.
>>> import timm
>>> model = timm.create_model('convit_small.fb_in1k', pretrained=True)
>>> data_config = timm.data.resolve_model_data_config(model)Model API support
✓ supported, ✓ (square) works for square sizes only, ✗ not supported, – not needed (the model already accepts any input
size). Checked by running each feature on a randomly initialized model (ConVit with convit_tiny at 224), other
architectures of the same class are expected to behave the same. See the Model API page for details.
Architectures
| Architecture | Params (M) | GMACs | Input size | Pretrained weights |
|---|---|---|---|---|
convit_base | 86.54 | 17.52 | 224 | 1 |
convit_small | 27.78 | 5.76 | 224 | 1 |
convit_tiny | 5.71 | 1.26 | 224 | 1 |
GMACs and parameter counts are for the default input size and classifier of each architecture, from the benchmark results.
Pretrained weights
Top-1 is ImageNet-1k validation accuracy from results-imagenet.csv at
the listed eval size, - if the weight has no ImageNet-1k result (e.g. pretraining or image-text weights). Classes is the
size of the pretrained classifier, none for weights without one.
