Git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/v0.9rc1Branch 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 masterSwitched to branch ‘master‘Your branch is up-to-date with ‘origin/master‘.
