PP-LCNetV2
Category: Efficient/Mobile · Code: timm/models/lcnetv2.py · Architectures: 3 · Pretrained weights: 4 (0 with ImageNet-1k results)
PP-LCNetV2 from PaddleClas is a CPU oriented network built on PP-LCNet. The depthwise convolutions of the later stages are re-parameterizable multi-scale branches, and SE and shortcuts are used sparingly to avoid latency penalties on CPU.

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('lcnetv2_base.paddle_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 (LCNetV2 with lcnetv2_small 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 |
|---|---|---|---|---|
lcnetv2_base | 6.69 | - | 224 | 2 |
lcnetv2_large | 10.54 | - | 224 | 1 |
lcnetv2_small | 4.13 | - | 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.
