1 Github三个区域

1.0 工作区(working directory)

本地的GitHub仓库,如:

|-- ipynb_test
|   |-- .git
|   |-- tensorflow_model.ipynb
|   `-- tensorflow_variable.ipynb

1.2 版本库(repository)

工作区的目录.git即Github的版本库,内容如下:

.

    |-- heads
    |   `-- master
    |-- remotes
    |   `-- origin

22 directories, 29 files

其中,Git会自动创建一个master分支和HEAD文件,该文件是指向master的指针,内容为ref: refs/heads/master.
git commit -m提交的信息会存储在版本库中,并将code上传至云端.

1.3 缓存区(cache)

缓存区用于存储Git的更新,即git add提交的变更都存储在缓存区,在.git文件中为index.
