一般有很多分支，我们clone到本地的时候一般都是master分支，那么如何切换到其他分支呢？主要命令如下：

1. 查看远程分支

$ git branch -a 
我在mxnet根目录下运行以上命令：

~/mxnet$ git branch -a * master remotes/origin/HEAD -> origin/master remotes/origin/master remotes/origin/nnvm remotes/origin/piiswrong-patch-1 remotes/origin/v0.9rc1

可以看到，我们现在在master分支下

2. 查看本地分支

~/mxnet$ git branch
* master

3. 切换分支

$ git checkout -b v0.9rc1 origin/v0.9rc1 Branch v0.9rc1 set up to track remote branch v0.9rc1 from origin. Switched to a new branch 'v0.9rc1' ＃已经切换到v0.9rc1分支了 $ git branch master * v0.9rc1 ＃切换回master分支 $ git checkout master Switched to branch 'master' Your branch is up-to-date with 'origin/master'.
