调用```paddle.init```指定使用4卡GPU训练;调用```data_provider.Settings```配置数据预处理所需参数,其中```cfg.IMG_HEIGHT```和```cfg.IMG_WIDTH```在配置文件```config/vgg_config.py```中设置,这里均为300,300x300是一个典型配置,兼顾效率和检测精度,也可以通过修改配置文件扩展到500x500;调用```train```执行训练,其中```train_file_list```指定训练数据列表,```dev_file_list```指定评估数据列表,```init_model_path```指定预训练模型位置。训练过程中会打印一些日志信息,每训练10个batch会输出当前的轮数、当前batch的cost及mAP(mean Average Precision),每训练一个pass,会保存一次模型,默认保存在```checkpoints```目录下(注:需事先创建)。
