## What it is
Official PyTorch implementation and training code for HRNet (High-Resolution Network) image classification models on ImageNet. It provides model definitions, training scripts, and pretrained checkpoints of HRNet backbones with a classification head.

## Use cases
- train an image classification model on ImageNet
- get HRNet pretrained backbone weights for transfer learning
- use HRNet as a backbone for detection or segmentation
- compare high-resolution network accuracy against ResNet
- export HRNet models to ONNX
- find small efficient classification models with ResNet18-level cost

## When to choose
- you need a strong high-resolution backbone for downstream vision tasks like pose estimation or segmentation
- you want pretrained ImageNet weights with competitive top-1 accuracy
- you need a ResNet replacement backbone in PyTorch

## When to avoid
- you need a maintained general-purpose model zoo or modern training framework
- you want inference-only deployment without training code
- you need models beyond classification such as detection heads included out of the box
