Paper: MaxViT: Multi-Axis Vision Transformer (arXiv:2204.01697) · HF Papers

MaxViT combines blocked local and dilated global attention (multi-axis) in a hierarchical CNN/Transformer hybrid.

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

Pure-Keras 3 conversion of timm/maxvit_base_tf_512.in21k_ft_in1k for zeromodels. One implementation runs unmodified on TensorFlow / Torch / JAX.

This is an image-classification / backbone checkpoint (MaxViTImageClassify / MaxViTModel).

✨ Quick start

python

import os

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

from PIL import Image
from zeromodels.models.maxvit import MaxViTImageClassify, MaxViTModel, MaxViTImageProcessor

model = MaxViTImageClassify.from_weights("zeromodels/maxvit_base_tf_512_in21k_ft_in1k")
processor = MaxViTImageProcessor.from_weights("zeromodels/maxvit_base_tf_512_in21k_ft_in1k")

image = Image.open("your_image.jpg").convert("RGB")
pixels = processor(image)  # resize + normalize (normalization lives in the processor)
logits = model(pixels, training=False)
print(logits.shape)  # (1, num_classes)

# Feature extraction: the backbone without the classifier head
backbone = MaxViTModel.from_weights("zeromodels/maxvit_base_tf_512_in21k_ft_in1k", as_backbone=True)
features = backbone(pixels, training=False)

Load any MaxViT variant the same way with from_weights("zeromodels/<variant>"):

Tips

Set KERAS_BACKEND before importing Keras / zeromodels.
MaxViTImageClassify returns class logits; MaxViTModel returns features (as_backbone=True for multi-scale stages).
See docs and Loading Weights.
Upstream / timm checkpoints: MaxViTImageClassify.from_weights("hf:timm/maxvit_base_tf_512.in21k_ft_in1k").

Special Thanks

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