打开在线Notebook—Jupyterlab

 打开CPU实例通常需要2-5分钟，打开GPU实例通常需要8-10分钟，请耐心等待

基于PAI-DSW在Jupyterlab内建模

第一次运行，需要加载相关的库和数据集

案例设计思路

1、载入数据集

afqmc（Ant Financial Question Matching Corpus）数据集

2、数据预处理

在ModelScope中，数据预处理与模型强相关，因此，在指定模型以后，ModelScope框架会自动从对应的modelcard中读取配置文件中的preprocessor关键字，自动完成预处理的实例化。

3、模型训练与评估

训练

根据参数实例化trainer对象，最后，调用train接口进行训练

评估

训练完成以后，配置评估数据集，直接调用trainer对象的evaluate函数，即可完成模型的评估。
