### DEMO2：多任务辅助训练与目标任务预测
> 本demo路径位于`demo/demo2`
本节我们考虑更加复杂的学习目标，我们引入一个掩码语言模型（Mask Language Model，MLM）问答匹配（QA Match）任务来辅助上一节MRQA任务的训练，相关训练数据分别位于`data/mlm4mrqa`和`data/match4mrqa`。并且我们这里换用ERNIE模型作为主干网络，来获得更佳的效果。在多任务训练结束后，我们使用训练好的模型来对MRQA任务的测试集进行预测。

Presidential spokesman Abigail Valte earlier Saturday urged residents of low-lying and mountainous areas that could be hit hard by the storm to evacuate, the state news agency said, citing an interview conducted on a government radio station. World Vision, the Christian humanitarian organization, said Saturday that it had to postpone some of its relief efforts due to Nalgae, with two of three emergency teams set to deploy once the storm passes. Another team is in Bulcan province, most of which is "still submerged" because of Nesat. The group is focusing its post-Nesat efforts on two communities in Manila and three in the northern Isabela and Zambales provinces.
