Inception-ResNet-v2
Category: CNN · Code: timm/models/inception_resnet_v2.py · Architectures: 1 · Pretrained weights: 2 (2 with ImageNet-1k results)
Inception-ResNet-v2 combines Inception modules with residual connections. Ported from the TensorFlow implementation and weights.

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('inception_resnet_v2.tf_ens_adv_in1k', pretrained=True)
>>> data_config = timm.data.resolve_model_data_config(model)Model API support
| Feature | InceptionResnetV2 |
|---|---|
features_only=True feature maps | ✓ (strides 2, 4, 8, 16, 32) |
forward_intermediates() | ✗ |
prune_intermediate_layers() | ✗ |
| Any input size, no changes needed | ✓ |
set_input_size() | – |
dynamic_img_size=True | – |
set_grad_checkpointing() | ✗ |
Layer-wise LR decay (group_matcher()) | ✓ |
reset_classifier() | ✓ |
✓ 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 (InceptionResnetV2 with inception_resnet_v2 at 299), 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 |
|---|---|---|---|---|
inception_resnet_v2 | 55.84 | 13.18 | 299 | 2 |
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.
