Anaconda 3.x安装GraphLab遇到的问题

因为需要，所以在自己的机器上使用GraphLab，但是出现了问题，如下：

1. 当我在Jupyter中键入：import graphlab，并执行的时候报错：

   ---------------------------------------------------------------------------
   ModuleNotFoundError                       Traceback (most recent call last)
   <ipython-input-3-986a457431da> in <module>()
   ----> 1 import graphlab
   
   ModuleNotFoundError: No module named 'graphlab'
   

   • 这是因为GraphLab目前支持的版本是2.x，而我的环境是3.x，故而报错找不到，解决方案：
     • 创建一个2.7的虚拟环境，cmd环境下执行：conda create -n gl-env python=2.7
     • 激活这个环境activate gl-env，否则报错：

       Could not find a version that satisfies the requirement graphlab-create>=2.1 (from GraphLab-Create-License==2.1) (from versions: )
       No matching distribution found for graphlab-create>=2.1 (from GraphLab-Create-License==2.1)
       

2. 在GraphLab官网注册，并通过邮件获取到Product Key执行下列命令安装GraphLab：

   pip install --upgrade --no-cache-dir https://get.graphlab.com/GraphLab-Create/<graphlab-version(当前2.1)>/<your-registered-email>/<your-product-key>/GraphLab-Create-License.tar.gz
   

   • 安装过程如果出现报错：Cannot uninstall 'certifi'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.，问题在于pip的版本问题，更新全局虚拟环境的pip版本：<Anaconda-Home>\envs\gl-env\python.exe -m pip install pip==9.0.1；
   • 还有一个红色的报错，不过最后还是安装完成了，不用管：DEPRECATION: Uninstalling a distutils installed project (certifi) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.；
   • 如果网络不好， 可以使用国内的pip源，就是在原有的安装命令最后添加-i <pip-source> --trusted-host <pip-source-host>，国内的pip源还是比较多的，整理了几个（右键复制链接），如下：阿里云pip源，中国科技大学pip源，豆瓣pip源，清华大学pip源， 中国科学技术大学pip源等；
3. 在Anaconda中切换到gl-env，安装Jupyter notebook，重启生效，运行Jupyter notebook，写入代码import graphlab，然后执行，结果报错：

   <pre style="box-sizing: border-box; overflow: auto; font-family: monospace; font-size: 14px; display: block; padding: 1px 0px; margin: 0px; line-height: inherit; word-break: break-all; word-wrap: break-word; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); border: 0px; border-radius: 0px; white-space: pre-wrap; vertical-align: baseline; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found.
   
   1\. Ensure user account has write permission to C:\Programs\Anaconda3\envs\gl-env\lib\site-packages\graphlab
   2\. Run graphlab.get_dependencies() to download and install them.
   3\. Restart Python and import graphlab again.

   • 在win上开启C:\Programs\Anaconda3\envs\gl-env\lib\site-packages\graphlab的所有权限；
   • 执行在JupyterNoteBook上执行graphlab.get_dependencies()，如果不成功，多试几次，我的浏览器上装了谷歌访问助手一直装不成功，禁用之后试了1次就成功了；
   • 重启，再次导入import graphlab就成功了
4. 每次需要使用虚拟环境的时候，需要执行命令：activate gl-env，即在Anaconda中切换环境即可；
   activate gl-env
