# HGNet-V2
[HGNetV2](https://github.com/PaddlePaddle/PaddleClas/blob/v2.6.0/docs/zh_CN/models/ImageNet1k/PP-HGNetV2.md) is a next-generation convolutional neural network (CNN) backbone built for optimal accuracy-latency tradeoff on NVIDIA GPUs. Building on the original[HGNet](https://github.com/PaddlePaddle/PaddleClas/blob/v2.6.0/docs/en/models/PP-HGNet_en.md), HGNetV2 delivers high accuracy at fast inference speeds and performs strongly on tasks like image classification, object detection, and segmentation, making it a practical choice for GPU-based computer vision applications.
You can find all the original HGNet V2 models under the [USTC](https://huggingface.co/ustc-community/models?search=hgnet) organization.

The example below demonstrates how to classify an image with [`Pipeline`] or the [`AutoModel`] class.
```py
import torch
from transformers import pipeline
pipeline = pipeline(
task="image-classification",
model="ustc-community/hgnet-v2",
dtype=torch.float16,
device=0
)
pipeline("http://images.cocodataset.org/val2017/000000039769.jpg")
```
```py
import torch
import requests
from transformers import HGNetV2ForImageClassification, AutoImageProcessor
from PIL import Image
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
model = HGNetV2ForImageClassification.from_pretrained("ustc-community/hgnet-v2")
processor = AutoImageProcessor.from_pretrained("ustc-community/hgnet-v2")
inputs = processor(images=image, return_tensors="pt")
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}")
```
