# Installation

We provide installation instructions for ImageNet classification experiments here.

## Dependency Setup
Create an new conda virtual environment
```
conda create -n convnext python=3.8 -y
conda activate convnext
```

Install [Pytorch](https://pytorch.org/)>=1.8.0, [torchvision](https://pytorch.org/vision/stable/index.html)>=0.9.0 following official instructions. For example:
```
pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 -f https://download.pytorch.org/whl/torch_stable.html
```

Clone this repo and install required packages:
```
git clone https://github.com/facebookresearch/ConvNeXt
pip install timm==0.3.2 tensorboardX six
```

The results in the paper are produced with `torch==1.8.0+cu111 torchvision==0.9.0+cu111 timm==0.3.2`.

## Dataset Preparation

Download the [ImageNet-1K](http://image-net.org/) classification dataset and structure the data as follows:
```
/path/to/imagenet-1k/
  train/
    class1/
      img1.jpeg
    class2/
      img2.jpeg
  val/
    class1/
      img3.jpeg
    class2/
      img4.jpeg
```

For pre-training on [ImageNet-22K](http://image-net.org/), download the dataset and structure the data as follows:
```
/path/to/imagenet-22k/
  class1/
    img1.jpeg
  class2/
    img2.jpeg
  class3/
    img3.jpeg
  class4/
    img4.jpeg
```
