请在智源资源下载页面进行申请，文件介绍如下：

文件名 描述 参数大小
100000.tar 纯中文模型 110亿
36000.tar 中英文双语模型 110亿
300000.tar 中英文MoE模型 1980亿

1 安装

可以直接拉取我们提供的 Docker 环境：

docker pull gyxthu17/cpm-2:1.0

2 数据

scripts/gen_data.sh 中给出了生成数据文件的脚本示例。该脚本将一个多行的纯文本文件（一个 document 一行）转化为二进制文件（会输出三个 .bin 和三个 .idx 文件），方便模型读取。

3 训练

首先需要将 WORKING_DIR 变量换成 CPM-2 目录的所在路径。调整 NUM_WORKERS 和 NUM_GPUS_PER_WORKER 指定机器数量与每台机器的 GPU 设备数量。修改 ${WORKING_DIR}/src/configs/host_files/hostfile-cpm2 文件将其中的主机名称替换成每台机器的 IP 地址或者和 IP 地址相关联的主机名称。

运行命令：

cd src
bash scripts/pretrain_enc_dec.sh
