Run EfficientNetV2 with Keras 3: JAX, PyTorch, or TensorFlow

kerasformers/tf_efficientnetv2_b0_in1k

Paper: EfficientNetV2: Smaller Models and Faster Training (arXiv:2104.00298) · HF Papers

EfficientNetV2 trains faster with Fused-MBConv and progressive learning. Same ImageClassify / Model API as EfficientNet.

For more details on the model, please go to the upstream model card.

Pure-Keras 3 conversion of timm/tf_efficientnetv2_b0.in1k for kerasformers. One implementation runs unmodified on TensorFlow / Torch / JAX.

This is an image-classification / backbone checkpoint (EfficientNetV2ImageClassify / EfficientNetV2Model).

✨ Quick start

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

from PIL import Image
import numpy as np
from kerasformers.models.efficientnetv2 import EfficientNetV2ImageClassify, EfficientNetV2Model

model = EfficientNetV2ImageClassify.from_weights("kerasformers/tf_efficientnetv2_b0_in1k")
backbone = EfficientNetV2Model.from_weights(
    "kerasformers/tf_efficientnetv2_b0_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 EfficientNetV2 variant the same way with from_weights("kerasformers/<variant>"):

Tips

• Set KERAS_BACKEND before importing Keras / kerasformers.
• EfficientNetV2ImageClassify returns class logits; EfficientNetV2Model returns features (as_backbone=True for multi-scale stages).
• See docs and Loading Weights.
• Upstream / timm checkpoints: EfficientNetV2ImageClassify.from_weights("hf:timm/tf_efficientnetv2_b0.in1k").

Special Thanks

A huge thank you to the EfficientNetV2 authors and the timm / Hub communities for creating and releasing these models.
