The code shows following errors:
ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll
The error exists for me as well after the following the above steps. What i realised is that the these two dependencies needs to be extracted in the "cython" folder inside "graphlab" folder. So i copied the same folder from a different installation that was working for me previously and volla.. "import graphlab" was successful. In case anyone needs it, below is the link to the zip of my "cython" folder. Just replace this "cython" folder inside graphlab (Usual location is '/Anaconda2/envs/gl-env/Lib/site-packages/graphlab'. I hope it helps someone
