# kerasformers/tf_efficientnet_lite2_in1k

Paper: [EfficientNet: Rethinking Model Scaling for Convolutional Neural Networks (arXiv:1905.11946)](https://arxiv.org/abs/1905.11946) · [HF Papers](https://huggingface.co/papers/1905.11946)

EfficientNet-Lite is the mobile/EdgeTPU-friendly EfficientNet family (no squeeze-excite, ReLU6). Classifier or backbone.

For more details on the model, please go to the upstream [model card](https://huggingface.co/timm/tf_efficientnet_lite2.in1k).

Pure-**Keras 3** conversion of [`timm/tf_efficientnet_lite2.in1k`](https://huggingface.co/timm/tf_efficientnet_lite2.in1k) for [kerasformers](https://github.com/IMvision12/KerasFormers). One implementation runs unmodified on **TensorFlow / Torch / JAX**.

This is an **image-classification / backbone** checkpoint (`EfficientNetLiteImageClassify` / `EfficientNetLiteModel`).

## ✨ Quick start

```python
import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

from PIL import Image
import numpy as np
from kerasformers.models.efficientnet_lite import EfficientNetLiteImageClassify, EfficientNetLiteModel

model = EfficientNetLiteImageClassify.from_weights("kerasformers/tf_efficientnet_lite2_in1k")
backbone = EfficientNetLiteModel.from_weights(
    "kerasformers/tf_efficientnet_lite2_in1k", as_backbone=True
)

image = Image.open("your_image.jpg").convert("RGB")
image = image.resize((224, 224))
x = np.asarray(image, dtype="float32")[None]  # (1, H, W, 3)
print(model(x).shape)  # (1, num_classes)
feats = backbone(x)
print(len(feats), [tuple(f.shape) for f in feats])
```

Load any EfficientNet-Lite variant the same way with `from_weights("kerasformers/<variant>")`:

| Variant | Hub |
|---|---|
| `tf_efficientnet_lite0_in1k` | [`kerasformers/tf_efficientnet_lite0_in1k`](https://huggingface.co/kerasformers/tf_efficientnet_lite0_in1k) |
| `tf_efficientnet_lite1_in1k` | [`kerasformers/tf_efficientnet_lite1_in1k`](https://huggingface.co/kerasformers/tf_efficientnet_lite1_in1k) |
| `tf_efficientnet_lite2_in1k` | [`kerasformers/tf_efficientnet_lite2_in1k`](https://huggingface.co/kerasformers/tf_efficientnet_lite2_in1k) |
| `tf_efficientnet_lite3_in1k` | [`kerasformers/tf_efficientnet_lite3_in1k`](https://huggingface.co/kerasformers/tf_efficientnet_lite3_in1k) |
| `tf_efficientnet_lite4_in1k` | [`kerasformers/tf_efficientnet_lite4_in1k`](https://huggingface.co/kerasformers/tf_efficientnet_lite4_in1k) |

## Tips

- Set `KERAS_BACKEND` **before** importing Keras / kerasformers.
- `EfficientNetLiteImageClassify` returns class logits; `EfficientNetLiteModel` returns features (`as_backbone=True` for multi-scale stages).
- See [docs](https://imvision12.github.io/KerasFormers/classification_backbones/) and [Loading Weights](https://imvision12.github.io/KerasFormers/loading_weights/).
- Upstream / timm checkpoints: `EfficientNetLiteImageClassify.from_weights("hf:timm/tf_efficientnet_lite2.in1k")`.

## Special Thanks

A huge thank you to the EfficientNet-Lite authors and the timm / Hub communities for creating and releasing these models.
