万事开头难，为了导入GraphLab包，花了我两个多小时。
问题描述：
在Jupyter Notebook 中执行import graphlab命令后，出现以下提示：
“
ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found.
1. Ensure user account has write permission to C:\Users\pande\Anaconda2\envs\gl-env\lib\site-packages\graphlab
2. Run graphlab.get_dependencies() to download and install them.
3. Restart Python and import graphlab again.
By running the above function, you agree to the following licenses.
* libstdc++: https://gcc.gnu.org/onlinedocs/libstdc++/manual/license.html
* xz: http://git.tukaani.org/?p=xz.git;a=blob;f=COPYING
“
然后，按照提示，执行graphlab.get_dependencies()命令，结果又出现以下错误：

然后，就没辙了。
只能求助于万能的互联网了。
以下文章对我帮助很大：

于是，按照这篇文章提供的方法，手动更新了dependencies.py文件，在Python Terminal (命令行工具，而不是Jupyter Notebook)中运行graphlab.get_dependencies()命令，终于成功了。
Welcome to the GraphLab Create Terminal This terminal gives you access to the 'gl-env' Python environment where GraphLab Create and other useful packages, such as IPython and Jupyter Notebook, have been installed. Use 'conda' or 'pip' to manage packages for development. Your gl-env environment has been activated using the following command: activate gl-env To get started, type the commands 'ipython' and then 'import graphlab'. To open Jupyter Notebook, type 'jupyter notebook'.
