FocalTransformer for PyTorch

概述

简述

FocalTransformer是一个图像分类网络,网络使用粗粒度和细粒度两种模式分别汇聚远距离和近距离的token信息,并且使用多尺度的金字塔结构,这使得它比ViT更有效地聚合全局信息,同时计算复杂度不会超出ViT太多。

  • 参考实现:

    url=https://github.com/microsoft/Focal-Transformer.git
    commit_id=57bb3031582a2afb2d2a6916612bc4311316f9fc
    
  • 适配昇腾 AI 处理器的实现:

    url=https://gitcode.com/ascend/ModelZoo-PyTorch.git
    code_path=PyTorch/contrib/cv/classification
    

准备训练环境

该模型为不随版本演进模型(随版本演进模型范围可在此处查看),未在最新昇腾配套软件中适配验证,您可以:

  1. 根据下面提供PyTorch版本在软件版本配套表中选择匹配的CANN等软件下载使用。
  2. 查看软件版本配套表后确认对该模型有新版本PyTorch和CANN中的适配需求,请在modelzoo/issues中提出您的需求。自行适配不保证精度和性能达标。

准备环境

  • 当前模型支持的 PyTorch 历史版本和已知三方库依赖如下表所示。

    表 1 版本支持表

    Torch_Version 三方库依赖版本
    PyTorch 1.5 torchvision==0.2.2.post3;pillow==8.4.0
    PyTorch 1.8 torchvision==0.9.1;pillow==9.1.0
  • 环境准备指导。

    请参考《Pytorch框架训练环境准备》。

  • 安装依赖。

    在模型源码包根目录下执行命令,安装模型对应PyTorch版本需要的依赖。

    pip install -r 1.5_requirements.txt  # PyTorch1.5版本
    
    pip install -r 1.8_requirements.txt  # PyTorch1.8版本
    

    说明: 只需执行一条对应的PyTorch版本依赖安装命令。

准备数据集

  1. 获取数据集。

    用户自行获取原始数据集,可选用的开源数据集包括ImageNet2012,将数据集上传到服务器任意路径下并解压。 数据集目录结构参考如下所示。

    ├── ImageNet2012
          ├──train
               ├──类别1
                     │──图片1
                     │──图片2
                     │   ...       
               ├──类别2
                     │──图片1
                     │──图片2
                     │   ...   
               ├──...                     
          ├──val  
               ├──类别1
                     │──图片1
                     │──图片2
                     │   ...       
               ├──类别2
                     │──图片1
                     │──图片2
                     │   ...              
    

    说明: 该数据集的训练过程脚本只作为一种参考示例。

开始训练

训练模型

  1. 进入解压后的源码包根目录。

    cd /${模型文件夹名称} 
    
  2. 运行训练脚本。

    该模型支持单机单卡训练和单机8卡训练。

    • 单机单卡训练

      启动单卡训练。

      bash ./test/train_performance_1p.sh --data_path=/data/xxx/  # 单卡性能
      
    • 单机8卡训练

      启动8卡训练。

      bash ./test/train_full_8p.sh --data_path=/data/xxx/  # 8卡精度
      
      bash ./test/train_performance_8p.sh --data_path=/data/xxx/  # 8卡性能
      

    --data_path参数填写数据集路径,需写到数据集的一级目录。

    模型训练脚本参数说明如下。

    公共参数:
    --cfg                               //config路径
    --data-path                         //数据集路径
    --batch-size                        //训练批次大小
    --stop_step                         //性能测试停止步数
    

    训练完成后,权重文件保存在output文件夹下,并输出模型训练精度和性能信息。
