This repository contains Pytorch evaluation code, training code and pretrained models for the following projects:

• SPACH (A Battle of Network Structures: An Empirical Study of CNN, Transformer, and MLP)
• sMLP (Sparse MLP for Image Recognition: Is Self-Attention Really Necessary?)
• ShiftViT (When Shift Operation Meets Vision Transformer: An Extremely Simple Alternative to Attention Mechanism)

Other unofficial implementations:

• ShiftViT
  • Keras by Aritra Roy Gosthipaty and Ritwik Raha
• SPACH
  • PyTorch with NPU by Junming Chen

Main Results on ImageNet with Pretrained Models

Usage

NPU

NPU means neural-network processing units.

To enable NPU, use parser argument

--npu

Install

First, clone the repo and install requirements:

git clone https://github.com/Leoooo333/SPACH-1

• install requirement

pip3 install torchvision==0.6.0
pip3 install einops==0.4.1
pip3 install --no-deps timm==0.4.5

# other recommended requirements
apex==0.1+ascend.20220315
torch==1.5.0+ascend.post5.20220315

• source env and build：

source ./test/env_npu.sh

Data preparation

Download and extract ImageNet train and val images from http://image-net.org/. The directory structure is the standard layout for the torchvision datasets.ImageFolder, and the training and validation data is expected to be in the train/ folder and val/ folder respectively:

/path/to/imagenet/
  train/
    class1/
      img1.jpeg
    class2/
      img2.jpeg
  val/
    class1/
      img3.jpeg
    class/2
      img4.jpeg

Training & Evaluation

One can simply call the following script to run training process. Distributed training is recommended even on single GPU node.

To train a model on NPU, run main.py with the desired model architecture and the path to the ImageNet dataset:

# training 1p accuracy
bash ./test/train_full_1p.sh --model=model_name \
--data_path=real_data_path

# training 1p performance
bash ./test/train_performance_1p.sh --model=model_name \
--data_path=real_data_path

# training 8p accuracy
bash ./test/train_full_8p.sh --model=model_name \
--data_path=real_data_path

# training 8p performance
bash ./test/train_performance_8p.sh --model=model_name \
--data_path=real_data_path

#evaluate 8p accuracy
bash ./test/train_eval_8p.sh --model=model_name \
--data_path=real_data_path \
--resume=checkpoint_path
