# Introduction
|
|
This example introduce how to pretrain roberta from scratch, including preprocessing, pretraining, finetune. The example can help you quickly train a high-quality roberta.
|
|
|
|
## 0. Prerequisite
|
|
- Install Colossal-AI
|
|
- Editing the port from `/etc/ssh/sshd_config` and `/etc/ssh/ssh_config`, every host expose the same ssh port of server and client. If you are a root user, you also set the **PermitRootLogin** from `/etc/ssh/sshd_config` to "yes"
|
|
- Ensure that each host can log in to each other without password. If you have n hosts, need to execute n<sup>2</sup> times
|
|
|
|
```
|
|
ssh-keygen
|
|
ssh-copy-id -i ~/.ssh/id_rsa.pub ip_destination
|
|
```
|
|
|
|
- In all hosts, edit /etc/hosts to record all hosts' name and ip.The example is shown below.
|
|
|
|
```bash
|
|
192.168.2.1 GPU001
|
|
192.168.2.2 GPU002
|
|
192.168.2.3 GPU003
|
|
192.168.2.4 GPU004
|
|
192.168.2.5 GPU005
|
|
192.168.2.6 GPU006
|
|
192.168.2.7 GPU007
|
|
...
|
|
```
|
|
|
|
- restart ssh
|
|
```
|
|
service ssh restart
|
|
```
|
|
|
|
## 1. Corpus Preprocessing
|
|
```bash
|
|
cd preprocessing
|
|
```
|
|
following the `README.md`, preprocess original corpus to h5py plus numpy
|
|
|
|
## 2. Pretrain
|
|
|
|
```bash
|
|
cd pretraining
|
|
```
|
|
following the `README.md`, load the h5py generated by preprocess of step 1 to pretrain the model
|
|
|
|
## 3. Finetune
|
|
|
|
The checkpoint produced by this repo can replace `pytorch_model.bin` from [hfl/chinese-roberta-wwm-ext-large](https://huggingface.co/hfl/chinese-roberta-wwm-ext-large/tree/main) directly. Then use transformers from Hugging Face to finetune downstream application.
