```
|
||||
|
||||
## 数据处理流程
|
||||
### 单个数据集处理
|
||||
预训练语料为无监督形式,不需要区分问题与答案,但需要将数据转为index后进行模型训练。我们拿到的原始数据可能是两种形式:
|
||||
- 文件格式为.txt的原始文本,处理流程为:数据→jsonl格式的数据→index数据
|
||||
- 文件格式为.jsonl的文本数据,处理流程为j:数据→index数据
|
||||
1. 参考以下脚本,将txt数据处理为jsonl格式:
|
||||
```python
|
||||
# convert_txt2jsonl.py
|
||||
|
||||
import json
|
||||
import sys
|
||||
|
||||
for line in sys.stdin:
|
||||
if line.strip() == "":
|
||||
continue
|
||||
temp_json = {"input": "", "output": line.strip()}#预训练计算Loss时只计算output部分,所以input字段为空
|
||||
print(json.dumps(temp_json, ensure_ascii=False))
|
||||
```
|
||||
脚本使用方法如下,其中pretrain.txt是原始txt数据,pretrain.jsonl是输出的jsonl格式数据:
|
||||
```shell
|
||||
cat pretrain.txt | python convert_txt2jsonl.py > pretrain.jsonl
|
||||
```
|
||||
输出的jsonl文件中,其中每一行有两个字段:input字段与output字段。例如:
|
||||
```JSON
|
||||
{"input":"","output":"中国的首都是北京。"}
|
||||
```
|
||||
2. jsonl格式转index。脚本位于./quick_start_clean/convert_json2index.py,应用方法如下:
|
||||
```shell
|
||||
python convert_json2index.py \
|
||||
--path ../data_process/data \ #存放jsonl文件的目录
|
||||
--language zh \ #只能选择zh(中文)或者en(英文)
|
||||
--output ../data_process/data_index \ #存放生成的index的目录,与原先存放jsonl文件的目录不能相同
|
||||
--hdfs_name index #index文件的文件名
|
||||
```
|
||||
脚本运行成功时,会有如下显示:(不需要用hadoop所以不用管hadoop: not found的警告信息)
|
||||
![alt text](055bf7ce-faab-403b-a7ee-896279bee11f.png)
|
||||
|
||||
转完后,在index的目录下会生成四个文件:data.jsonl(原先的jsonl数据)、index、index.h5、meta.json(记录数据集信息,包含 "language", "nlines", "nbytes", "length_distribute", "avg_token_per_line", "hdfs_path", "data_sample"字段)。
|
||||
这里有一个meta.json的例子:
|
||||
```JSON
|
||||
{"language": "en", "nlines": 68912, "nbytes": 41801261, "length_distribute": {"less_4k": 68911, "4k-8k": 1, "8k-16k": 0, "16k-32k": 0, "32k-64k": 0, "64k-128k": 0, "128k-256k": 0, "more_256k": 0}, "avg_token_per_line": 145.23292024611098, "hdfs_path": "/user/tc_agi/llm/index_datasets/index", "data_sample": {"input": "<用户>For a car, what scams can be plotted with 0% f...", "output": "The car deal makes money 3 ways. If you pay in one...", "source": "finance_cpm9g"}}
|
||||
```
|
||||
|
||||
### 多个数据集混合
|
||||
我们支持多个数据集的混合读入,并设置不同数据集的比例。为此,需要准备一个数据混合的json文件,来指导训练过程中的数据读取策略,示例如下:
|
||||
```JSON
|
||||
[
|
||||
{
|
||||
"dataset_name": "humanevallike_clean_dedup",
|
||||
"task_name": "humanevallike_clean_dedup",
|
||||
"abs_weight": 0.2,
|
||||
"path": "/data/0124_hq_data/humanevallike_clean_dedup",
|
||||
"transforms": "0124_hq_data/general/script_cpmc.py",
|
||||
"allow_repeat": true,
|
||||
"nlines": 995339,
|
||||
"ave_tokens_per_line": 100,
|
||||
"total_tokens": 0.1
|
||||
},
|
||||
{
|
||||
"dataset_name": "leetcode_pass_code_0125",
|
||||
"task_name": "leetcode_pass_code_0125",
|
||||
"abs_weight": 0.006,
|
||||
"path": "/data/0124_hq_data/leetcode_pass_code_0125",
|
||||
"transforms": "0124_hq_data/general/script_cpmc.py",
|
||||
"allow_repeat": true,
|
||||
"nlines": 10724,
|
||||
"ave_tokens_per_line": 200,
|
||||
"total_tokens": 0.002
|
||||
}
|
||||
]
|
||||
```
|
||||
其中abs_weight需要自行设计;path、nlines、ave_tokens_per_line可以参考生成index时的meta.json进行填写;allow_repeat为数据集是否需要复制;total_tokens为估计的数据集token总数,以b(十亿)为单位,例如0.1代表0.1b个token,transforms为读入训练数据的脚本路径,该脚本可以参考以下代码:
|
||||
```python
|
||||
# script_cpmc.py
|
||||
import random
|
||||
|
||||
def rand(n: int, r: random.Random):
|
||||
return int(r.random() * n)
|
||||
|
||||
def transform(data, num_sample: int, r: random.Random):
|
||||
if 'input' in data:
|
||||
_input = data['input']
|
||||
else:
|
||||
_input = ""
|
||||
|
||||
if 'output' in data:
|
||||
_output = data['output']
|
||||
else:
|
||||
_output = ""
|
||||
return {"input": _input,
|
||||
"output": _output,
|
||||
}
|
||||
```
|
||||
## 单机训练
|
||||
1. 修改/apps/fm9g_2b/train_configs/2.4b.json中的训练参数,这一部分的参数设置会覆盖掉shell脚本中的相应部分。
|
||||
2. 修改FM_9G-master/FM_9G-master/apps/fm9g_2b/pretrain_dragonfly.sh中最后部分的训练参数,如下所示:
|
||||
```shell
|
||||
GPUS_PER_NODE=2 #该节点上需要的GPU数量
|
||||
NNODES=1 #单机训练无需修改这个参数
|
||||
RANK=0 #单机训练无需修改这个参数
|
||||
MASTER_ENDPOINT=g3006 #该节点名称
|
||||
MASTER_PORT=12345 #该节点端口,注意避免端口冲突
|
||||
```
|
||||
3. 激活自己的训练环境:
|
||||
```shell
|
||||
conda activate fm-9g
|
||||
```
|
||||
4. 指定要用的GPU:
|
||||
```shell
|
||||
export CUDA_VISIBLE_DEVICES=0,1
|
||||
```
|
||||
5. 切换到fm9g_2b目录下,运行训练脚本:
|
||||
```shell
|
||||
cd FM_9G-master/FM_9G-master/apps/fm9g_2b
|
||||
bash pretrain_dragonfly.sh
|
||||
```
|
||||
## 多机训练
|
||||
需要保证机器之间能够通信,且每台机器上的训练环境、代码、数据等一致。以下教程以使用slurm调度的算力平台为例。
|
||||
常用的slurm命令包括:
|
||||
```
|
||||
slurm命令 功能
|
||||
------------------------------
|
||||
sinfo 查看集群分区状态
|
||||
squeue 查看作业队列
|
||||
srun, salloc 交互式运行作业
|
||||
sbatch 提交作业
|
||||
scancel 取消作业
|
||||
scontrol 查看和修改作业参数
|
||||
sacct 查看已完成作业
|
||||
```
|
||||
注意:#slurm的多节点通信与bmtrain的环境变量有冲突,且srun不稳定,推荐采用slurm提交多个单节点任务,用torchrun的方式实现多节点通信。
|
||||
1. 参考以下代码,编写主节点启动脚本run_master.sh:
|
||||
```shell
|
||||
#!/bin/bash
|
||||
#SBATCH --partition=long
|
||||
#SBATCH --nodes=1 #需要的节点数量,即需要几台机器,不建议修改,多机训练时提交多个单节点任务即可
|
||||
#SBATCH --tasks-per-node=8 #每个节点的进程数,和每节点的GPU数量保持一致
|
||||
#SBATCH --gres=gpu:8 #每个节点上需要几块GPU
|
||||
#SBATCH --cpus-per-task=8 #每个任务分配的CPU数量(建议不要修改),该节点的cpu总数为任务数乘以每个任务的cpu数,这个示例脚本中的cpu总数为8x8=64
|
||||
MASTER_ADDR=`hostname`
|
||||
echo $MASTER_ADDR #可以在slurm-xxx.out中查看申请的主节点名称
|
||||
|
||||
while true;do
|
||||
sleep 5s #
|
||||
```
|
||||
2. 启动主节点:
|
||||
```shell
|
||||
sbatch --nodelist g3002 run_master.sh
|
||||
```
|
||||
3. 登录主节点,激活训练环境:
|
||||
```shell
|
||||
ssh g3002 #登录节点
|
||||
conda activate fm-9g #激活训练环境
|
||||
export CUDA_VISIBLE_DEVICES=0,1 #指定要用的GPU
|
||||
```
|
||||
4. 修改主节点训练脚本:在/apps/fm9g_2b/pretrain_dragonfly.sh的最后修改主节点名称、端口、机器数量、GPU数量,并将脚本重命名为pretrain_dragonfly_master.sh,方便区分:
|
||||
```shell
|
||||
GPUS_PER_NODE=2 #本节点上要用的GPU数量
|
||||
NNODES=2 #机器数量
|
||||
RANK=0 #0为主节点,1/2/3…为从节点
|
||||
MASTER_ENDPOINT=g3002 #主节点名称
|
||||
MASTER_PORT=12345 #主节点端口号,注意避免端口冲突
|
||||
```
|
||||
5. 提交主节点训练脚本:
|
||||
```shell
|
||||
cd FM_9G-master/FM_9G-master/apps/fm9g_2b
|
||||
bash pretrain_dragonfly_master.sh
|
||||
```
|
||||
6. 启动从节点、激活训练环境,指定要用的卡,方法与主节点一样。
|
||||
7. 修改从节点训练脚本:将单机多卡的训练脚本重命名为pretrain_dragonfly_slave.sh,在末尾修改主节点名称、端口、机器数量、GPU数量:
|
||||
```shell
|
||||
GPUS_PER_NODE=2 #本节点上要用的GPU数量
|
||||
NNODES=2 #机器数量
|
||||
RANK=0 #0为主节点,1/2/3…为从节点
|
||||
MASTER_ENDPOINT=g3002 #主节点名称
|
||||
MASTER_PORT=12345 #主节点端口号,注意避免端口冲突
|
||||
```
|
||||
8. 提交从节点训练脚本:
|
||||
```shell
|
||||
cd FM_9G-master/FM_9G-master/apps/fm9g_2b
|
||||
bash pretrain_dragonfly_slave.sh
|
||||
```
|
||||
9. 如果有三台及以上的机器,重复6-8,注意修改RANK编号
|
||||
10. 开始训练后,每个iter的loss、lr等信息将在从节点上显示
|
||||
|
||||

```
|
||||
|
||||
## 查看训练情况
|
||||
1. 用tensorboard查看各个loss曲线与学习率等变化情况:
|
||||
```shell
|
||||
tensorboard –-logdir /apps/fm9g_2b/data/tensorboard/2b_0701 #存放.events文件的路径
|
||||
```
|
||||
2. 出现以下报错信息时,说明protobuf版本过高,重新装一个低版本的即可:
|
||||
```shell
|
||||
TypeError: MessageToJson() got an unexpected keyword argument 'including_default_value_fields'
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
1. Conda安装pytorch时卡在solving environment:网络问题。
|
||||
解决方法:
|
||||
- 采用镜像源;
|
||||
- 用pip安装。安装时需要注意pytorch版本与cuda版本的对应,建议安装1.13.1及以上的版本。
|
||||
|
||||
2. 安装flash-attn时报错:ModuleNotFoundError: No module named 'packaging'。
|
||||
解决方法:pip install packaging即可。
|
||||
|
||||
3. flash attention 安装卡住:
|
||||
解决方法:从官方release下载对应版本(注意cuda、torch版本的对应) https://github.com/Dao-AILab/flash-attention/releases
|
||||
下载前先检查一下:
|
||||
```python
|
||||
import torch
|
||||
print(torch._C._GLIBCXX_USE_CXX11_ABI)
|
||||
```
|
||||
如果打印出来的结果是False,则选择文件名中带有abiFALSE的版本,否则选带有abiTRUE的版本。随后pip install +.whl文件名 即可。
|
||||
|
||||
4. 导入flash-attn时报错:undefined symbol: _ZN3c104cuda9SetDeviceEi。
|
||||
解决方法:建议检查flash-attn的版本与cuda、torch的版本是否对应。
|
||||
|
||||
5. 安装OpenDelta时,报错提示无法安装pandas 2.2.2版本:
|
||||
```shell
|
||||
error: Couldn't find a setup script in /tmp/easy_install-bgpiop4j/pandas-2.2.2.tar.gz
|
||||
```
|
||||
这是因为pandas 2.2.2需要python3.9及以上的版本。在python3.8的环境下,我们只需安装pandas 2.0.3版本即可。
|
||||
|
||||
6. 通过setup.py安装OpenDelta时报错:
|
||||
```shell
|
||||
error: aiohttp 4.0.0a1 is installed but aiohttp!=4.0.0a0,!=4.0.0a1; extra == "http" is required by {'fsspec'}
|
||||
```
|
||||
重新安装aiohttp即可,建议安装4.0.0以下的版本:
|
||||
```shell
|
||||
pip uninstall aiohttp
|
||||
pip install aiohttp==3.9.5
|
||||
```
