# Model Card for efficientnetv2_b0_pruned_40

This is a prunned version of the [Keras EfficientNetV2B0](https://keras.io/api/applications/efficientnet_v2/#efficientnetv2b0-function) model in a [toch-dag](https://github.com/TCLResearchEurope/torch-dag) format.

This model has rougly 40% of the original model FLOPs with minimal metrics drop.


| Model                                    | KMAPPs*         | M Parameters   | Accuracy (224x224)      |
| -----------                              | -----------     | -----------    | ------------------      |
| **Keras EfficientNetV2B (baseline)**   | 29           | 7.1           | 78.69%                  |
| **efficientnetv2_b0_pruned_40 (ours)**          | 11.7 **(40%)** | 4.5 **(63%)** | 76.7% **(↓ 1.99%)**    |


\***KMAPPs** thousands of FLOPs per input pixel

`KMAPPs(model) = FLOPs(model) / (H * W * 1000)`, where `(H, W)` is the input resolution.

The accuracy was calculated on the ImageNet-1k validation dataset. For details about image pre-processing, please refer to the original repository.

## How to Get Started with the Model

To load the model, You have to install [torch-dag](https://github.com/TCLResearchEurope/torch-dag#3-installation) library, which can be done using `pip` by

```
pip install torch-dag
```

then, clone this repository

```
# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install
git clone https://huggingface.co/TCLResearchEurope/efficientnetv2_b0_pruned_40
```

and now You are ready to load the model:

```
import torch_dag
import torch

model = torch_dag.io.load_dag_from_path('./efficientnetv2_b0_pruned_40')

model.eval()
out = model(torch.ones(1, 3, 224, 224))
print(out.shape)
```
