some issues

作者您好。心中有几个疑问，希望您能不吝赐教
1.pre-train上来就是一堆超参（这些超参在哪个文件里面的）;pre-train部分的最后一句是训练把，而且后面带了一堆参数？到底我要输入什么指令从而接下去运行。
2.我的服务器只有一个gpu，要运行你的代码，是不是要改一些配置？但是到底要改哪些参数
3.数据集的路径在哪个文件，没看到有
4."we use the English Wikipedia corpus and BookCorpus (Zhu et al., 2015) for pre-training. By concatenating these two datasets, we obtain a corpus with roughly 16GB in size. We set the vocabulary size (sub-word tokens) as 32,768. We use the GLUE (General Language Understanding Evaluation) dataset (Wang et al., 2018) as the downstream tasks to evaluate the performance of the pre-trained models".这个是原文中的内容，为什么要concatenating 两个数据集，具体怎么concat

@sanwei111 you may need to learn more about linux/unix shell, to run the commands.
You should crawl/download data by yourself.

The concat of two dataset is standard process in BETR pretraining. You can use cat command in Linux.
