四、快速使用

MindFormers套件对外提供两种使用和开发形式,为开发者提供灵活且简洁的使用方式和高阶开发接口。

方式一:使用已有脚本启动

用户可以直接clone整个仓库,按照以下步骤即可运行套件中已支持的任意configs模型任务配置文件,方便用户快速进行使用和开发:

  • 准备工作

    • step1:git clone mindformers
    git clone -b r0.3 https://gitee.com/mindspore/mindformers.git
    cd mindformers
    • step2: 准备相应任务的数据集,请参考docs目录下各模型的README.md文档准备相应数据集

    • step3:修改配置文件configs/{model_name}/task_config/{model_name}_dataset.yaml中数据集路径

    • step4:如果要使用分布式训练,则需提前生成RANK_TABLE_FILE

    # 不包含8本身,生成0~7卡的hccl json文件
    python mindformers/tools/hccl_tools.py --device_num [0,8]
  • 单卡启动:统一接口启动,根据模型 CONFIG 完成任意模型的单卡训练、微调、评估、推理流程

# 训练启动,run_status支持train、finetuen、eval、predict三个关键字,以分别完成模型训练、评估、推理功能,默认使用配置文件中的run_mode
python run_mindformer.py --config {CONFIG_PATH} --run_mode {train/finetune/eval/predict}
  • 多卡启动: scripts 脚本启动,根据模型 CONFIG 完成任意模型的单卡/多卡训练、微调、评估、推理流程
# 8卡分布式运行, DEVICE_RANGE = [0, 8], 不包含8本身
cd scripts
bash run_distribute.sh RANK_TABLE_FILE CONFIG_PATH DEVICE_RANGE RUN_MODE
  • 常用参数说明
RANK_TABLE_FILE: 由mindformers/tools/hccl_tools.py生成的分布式json文件
CONFIG_PATH: 为configs文件夹下面的{model_name}/run_*.yaml配置文件
DEVICE_ID: 为设备卡,范围为0~7
DEVICE_RANGE: 为单机分布式卡的范围, 如[0,8]为8卡分布式,不包含8本身
RUN_STATUS: 为任务运行状态,支持关键字 train\finetune\eval\predict

方式二:调用API启动

  • 准备工作

    • step 1:安装mindformers

    具体安装请参考第二章

    • step2: 准备数据

    准备相应任务的数据集,请参考docs目录下各模型的README.md文档准备相应数据集。

  • Trainer 快速入门

    用户可以通过以上方式安装mindformers库,然后利用Trainer高阶接口执行模型任务的训练、微调、评估、推理功能。

    • Trainer 训练\微调启动

    用户可使用Trainer.train接口完成模型的训练\微调\断点续训。

    from mindformers import Trainer
    
    cls_trainer = Trainer(task='image_classification', # 已支持的任务名
                          model='vit_base_p16', # 已支持的模型名
                          train_dataset="/data/imageNet-1k/train", # 传入标准的训练数据集路径,默认支持ImageNet数据集格式
                          eval_dataset="/data/imageNet-1k/val") # 传入标准的评估数据集路径,默认支持ImageNet数据集格式
    # Example 1: 开启训练复现流程
    cls_trainer.train()
    # Example 2: 加载集成的mae权重,开启微调流程
    cls_trainer.train(resume_or_finetune_from_checkpoint='mae_vit_base_p16', do_finetune=True)
    # Example 3: 开启断点续训功能(如训练10epochs中断)
    cls_trainer.train(resume_or_finetune_from_checkpoint=True, init_epochs=10)
    • Trainer 评估启动

    用户可使用Trainer.evaluate接口完成模型的评估流程。

    from mindformers import Trainer
    
    cls_trainer = Trainer(task='image_classification', # 已支持的任务名
                          model='vit_base_p16', # 已支持的模型名
                          eval_dataset="/data/imageNet-1k/val") # 传入标准的评估数据集路径,默认支持ImageNet数据集格式
    # Example 1: 开启评估已集成模型权重的复现流程
    cls_trainer.evaluate()
    # Example 2: 开启评估训练得到的最后一个权重
    cls_trainer.evaluate(eval_checkpoint=True)
    # Example 3: 开启评估指定的模型权重
    cls_trainer.evaluate(eval_checkpoint='./output/rank_0/checkpoint/mindformers.ckpt')
    结果打印示例(已集成的vit_base_p16模型权重评估分数):
    Top1 Accuracy=0.8317
    • Trainer 推理启动

    用户可使用Trainer.predict接口完成模型的推理流程。

    from mindformers import Trainer
    
    cls_trainer = Trainer(task='image_classification', # 已支持的任务名
                          model='vit_base_p16') # 已支持的模型名
    input_data = './cat.png' # 一张猫的图片
    # Example 1: 指定输入的数据完成模型推理
    predict_result_d = cls_trainer.predict(input_data=input_data)
    # Example 2: 开启推理(自动加载训练得到的最后一个权重)
    predict_result_b = cls_trainer.predict(input_data=input_data, predict_checkpoint=True)
    # Example 3: 加载指定的权重以完成推理
    predict_result_c = cls_trainer.predict(input_data=input_data, predict_checkpoint='./output/rank_0/checkpoint/mindformers.ckpt')
    print(predict_result_d)
    结果打印示例(已集成的vit_base_p16模型权重推理结果):
    {‘label’: 'cat', score: 0.99}
  • pipeline 快速入门

    MindFormers套件为用户提供了已集成模型的pipeline推理接口,方便用户体验大模型推理服务。

    • pipeline 使用

    from mindformers.tools.image_tools import load_image
    
    test_img = load_image("./sunflower.png") # 一朵太阳花图片
    classifier = pipeline("zero_shot_image_classification",
                          model='clip_vit_b_32',
                          candidate_labels=["sunflower", "tree", "dog", "cat", "toy"])
