SENet (legacy)
Category: CNN · Code: timm/models/senet.py · Architectures: 9 · Pretrained weights: 9 (9 with ImageNet-1k results)
SENet, SE-ResNet and SE-ResNeXt from Cadene’s pretrained models (legacy_*). The module is deprecated in favour of the
SE variants of the ResNet class.

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('legacy_seresnext50_32x4d.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 (SENet with legacy_seresnet18 at 224), other
architectures of the same class are expected to behave the same. See the Model API page for details.

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.
