我正在尝试将graphlab导入为我正在修读的Coursera课程的一部分。
我已经安装了conda。
当我导入graphlab时，会弹出一个警报，提示未找到某些dll。
这是我的跑步。

>>> import graphlab
ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found.
1. Ensure user account has write permission to C:\Users\MyUserName\AppData\Local\conda\conda\envs\mlfoundations\lib\site-packages\graphlab
2. Run graphlab.get_dependencies() to download and install them.
3. Restart Python and import graphlab again.

如上所述，我需要运行graphlab.get_dependencies()。
因此，在运行它时，将引发以下错误。
>>> graphlab.get_dependencies()
