### 1. 安装git lfs
|
||||
|
||||
```bash
|
||||
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh
|
||||
apt install git-lfs
|
||||
# 更好的方法
|
||||
conda install git-lfs
|
||||
|
||||
# 旧方法
|
||||
# curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh
|
||||
# apt install git-lfs
|
||||
```
|
||||
|
||||
### 2. 配置git和lfs
