MobileViT

MobileViT is a lightweight vision transformer for mobile devices that merges CNNs's efficiency and inductive biases with transformers global context modeling. It treats transformers as convolutions, enabling global information processing without the heavy computational cost of standard ViTs.

You can find all the original MobileViT checkpoints under the Apple organization.

Tip

• This model was contributed by matthijs.

Click on the MobileViT models in the right sidebar for more examples of how to apply MobileViT to different vision tasks.

The example below demonstrates how to do [Image Classification] with [Pipeline] and the [AutoModel] class.

from transformers import pipeline


classifier = pipeline(
   task="image-classification",
   model="apple/mobilevit-small",
   device=0,
)

preds = classifier("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg")
print(f"Prediction: {preds}\n")

import requests
import torch
from PIL import Image

from transformers import AutoImageProcessor, MobileViTForImageClassification


image_processor = AutoImageProcessor.from_pretrained(
   "apple/mobilevit-small",
   use_fast=True,
)
model = MobileViTForImageClassification.from_pretrained("apple/mobilevit-small", device_map="auto")

url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = image_processor(image, return_tensors="pt").to(model.device)

with torch.no_grad():
    logits = model(**inputs).logits
predicted_class_id = logits.argmax(dim=-1).item()

class_labels = model.config.id2label
predicted_class_label = class_labels[predicted_class_id]
print(f"The predicted class label is:{predicted_class_label}")

Notes

• Does not operate on sequential data, it's purely designed for image tasks.
• Feature maps are used directly instead of token embeddings.
• Use [MobileViTImageProcessor] to preprocess images.
• If using custom preprocessing, ensure that images are in BGR format (not RGB), as expected by the pretrained weights.
• The classification models are pretrained on ImageNet-1k.
• The segmentation models use a DeepLabV3 head and are pretrained on PASCAL VOC.
