README
# SparK: the first successful BERT/MAE-style pretraining on *any* convolutional networks [](https://www.reddit.com/r/MachineLearning/comments/10ix0l1/r_iclr2023_spotlight_the_first_bertstyle/) [](https://twitter.com/keyutian/status/1616606179144380422)
This is the official implementation of ICLR paper [Designing BERT for Convolutional Networks: ***Spar***se and Hierarchical Mas***k***ed Modeling](https://arxiv.org/abs/2301.03580), which can pretrain **any CNN** (e.g., ResNet) in a **BERT-style self-supervised** manner.
We've tried our best to make the codebase clean, short, easy to read, state-of-the-art, and only rely on minimal dependencies.

## 🕹️ Colab Visualization Demo
Check [pretrain/viz_reconstruction.ipynb](pretrain/viz_reconstruction.ipynb) for visualizing the reconstruction of SparK pretrained models, like:
We also provide [pretrain/viz_spconv.ipynb](pretrain/viz_spconv.ipynb) that shows the "mask pattern vanishing" issue of dense conv layers.
## What's new here?
### 🔥 Pretrained CNN beats pretrained Swin-Transformer:
### 🔥 After SparK pretraining, smaller models can beat un-pretrained larger models:
### 🔥 All models can benefit, showing a scaling behavior:
### 🔥 Generative self-supervised pretraining surpasses contrastive learning:
#### See our [paper](https://arxiv.org/pdf/2301.03580.pdf) for more analysis, discussions, and evaluations.

## Installation & Running
We highly recommended you to use `torch==1.10.0`, `torchvision==0.11.1`, and `timm==0.5.4` for reproduction.
Check [INSTALL.md](INSTALL.md) to install all pip dependencies.
- **Loading pretrained model weights in 3 lines**
```python3
# download our weights `resnet50_1kpretrained_timm_style.pth` first
import torch, timm
res50, state = timm.create_model('resnet50'), torch.load('resnet50_1kpretrained_timm_style.pth', 'cpu')
res50.load_state_dict(state.get('module', state), strict=False) # just in case the model weights are actually saved in state['module']
```
- **Pretraining**
- any ResNet or ConvNeXt on ImageNet-1k: see [pretrain/](pretrain)
- **your own CNN model**: see [pretrain/](pretrain), especially [pretrain/models/custom.py](pretrain/models/custom.py)
- **Finetuning**
- any ResNet or ConvNeXt on ImageNet-1k: check [downstream_imagenet/](downstream_imagenet) for subsequent instructions.
- ResNets on COCO: see [downstream_d2/](downstream_d2)
- ConvNeXts on COCO: see [downstream_mmdet/](downstream_mmdet)
