# MobileViTv2 + DeepLabv3 (shehan97/mobilevitv2-1.0-voc-deeplabv3)
|
10 |
+
|
11 |
+
<!-- Provide a quick summary of what the model is/does. -->
|
12 |
+
MobileViTv2 model pre-trained on PASCAL VOC at resolution 512x512.
|
13 |
+
It was introduced in [Separable Self-attention for Mobile Vision Transformers](https://arxiv.org/abs/2206.02680) by Sachin Mehta and Mohammad Rastegari, and first released in [this](https://github.com/apple/ml-cvnets) repository. The license used is [Apple sample code license](https://github.com/apple/ml-cvnets/blob/main/LICENSE).
|
14 |
+
|
15 |
+
Disclaimer: The team releasing MobileViT did not write a model card for this model so this model card has been written by the Hugging Face team.
|
16 |
+
|
17 |
+
### Model Description
|
18 |
+
|
19 |
+
<!-- Provide a longer summary of what this model is. -->
|
20 |
+
MobileViTv2 is constructed by replacing the multi-headed self-attention in MobileViT with separable self-attention.
|
21 |
+
|
22 |
+
The model in this repo adds a [DeepLabV3](https://arxiv.org/abs/1706.05587) head to the MobileViT backbone for semantic segmentation.
|
23 |
+
|
24 |
+
### Intended uses & limitations
|
25 |
+
|
26 |
+
You can use the raw model for semantic segmentation. See the [model hub](https://huggingface.co/models?search=mobilevitv2) to look for fine-tuned versions on a task that interests you.
|
27 |
+
|
28 |
+
### How to use
|
29 |
+
|
30 |
+
Here is how to use this model:
|
31 |
+
|
32 |
+
```python
|
33 |
+
from transformers import MobileViTv2FeatureExtractor, MobileViTv2ForSemanticSegmentation
|
34 |
+
from PIL import Image
|
35 |
+
import requests
|
36 |
+
|
37 |
+
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
|
38 |
+
image = Image.open(requests.get(url, stream=True).raw)
|
39 |
+
|
40 |
+
feature_extractor = MobileViTv2FeatureExtractor.from_pretrained("shehan97/mobilevitv2-1.0-voc-deeplabv3")
|
41 |
+
model = MobileViTv2ForSemanticSegmentation.from_pretrained("shehan97/mobilevitv2-1.0-voc-deeplabv3")
|
42 |
+
|
43 |
+
inputs = feature_extractor(images=image, return_tensors="pt")
|
44 |
+
|
45 |
+
outputs = model(**inputs)
|
46 |
+
logits = outputs.logits
|
47 |
+
|
48 |
+
predicted_mask = logits.argmax(1).squeeze(0)
|
49 |
+
```
|
50 |
+
|
51 |
+
Currently, both the feature extractor and model support PyTorch.
|
52 |
+
|
53 |
+
## Training data
|
54 |
+
|
55 |
+
The MobileViT + DeepLabV3 model was pretrained on [ImageNet-1k](https://huggingface.co/datasets/imagenet-1k), a dataset consisting of 1 million images and 1,000 classes, and then fine-tuned on the [PASCAL VOC2012](http://host.robots.ox.ac.uk/pascal/VOC/) dataset.
