如何添加分支作为分支？

Question

Caffe的fork很多，比如MS有自己的Caffefork.

我想做的是将一些分支与原始 Caffe 的主分支进行比较。

我知道使用 git 我可以 compare 2 branches，但我的问题是如何添加分支作为分支。

我试过了this:

git clone https://github.com/BVLC/caffe.git
Cloning into 'caffe'...
remote: Counting objects: 32907, done.
remote: Total 32907 (delta 0), reused 0 (delta 0), pack-reused 32907
Receiving objects: 100% (32907/32907), 43.55 MiB | 571 KiB/s, done.
Resolving deltas: 100% (21962/21962), done.

cd caffe_BVLC/

git branch -l
* master

git remote add caffe_MS https://github.com/Microsoft/caffe.git

git remote -v
caffe_MS    https://github.com/Microsoft/caffe.git (fetch)
caffe_MS    https://github.com/Microsoft/caffe.git (push)
origin  https://github.com/BVLC/caffe.git (fetch)
origin  https://github.com/BVLC/caffe.git (push)

git fetch caffe_MS

From https://github.com/Microsoft/caffe
 * [new tag]         0.1w       -> 0.1w

git branch -l
* master

git checkout --track caffe_MS/MS
fatal: git checkout: updating paths is incompatible with switching branches.
Did you intend to checkout 'caffe_MS/MS' which can not be resolved as commit?

我做错了什么，我应该指定哪个分支名称？

Answer 1

更新

您使用的是 git 的旧版本。更新至 git >= 2 以使以下命令生效。我正在使用 2.4.10.

以下命令可以解决问题：

# Clone repo
git clone https://github.com/BVLC/caffe.git
cd caffe

# Add remote
git remote add caffe_MS https://github.com/Microsoft/caffe.git

# Fetch remote master from fork
git fetch caffe_MS master

# Compare to local master
# We are currently working in the local master that's why it can be omitted
git diff caffe_MS/master

Answer 2

I know that using git I can compare 2 branches, but my question is how to add fork as branch.

当你说你知道如何比较两个分支时，我想你的意思是你真的知道如何比较本地分支，并且你缺少的是如何比较远程分支。

首先，您可以看到远程分支列表：

git branch -r

并且您可以通过在远程名称前加上前缀来比较远程分支，例如：

git diff origin/master caffe_MS/master

至于最后一个错误，不清楚您要用 git checkout --track caffe_MS/MS 做什么。你的解释是关于比较分支和添加分支，你从来没有提到跟踪。如果你想从一个分支中检出一个分支，你可以使用与检出原始分支时相同的语法：

git checkout -b caffe_MS_master caffe_MS/master
