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('pnasnet5large.tf_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 (PNASNet5Large with pnasnet5large at 331),
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 |
|---|---|---|---|---|
pnasnet5large | 86.06 | 25.04 | 331 | 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.
