which eigen version? #78

Closed WenchenLi closed 8 years ago

WenchenLi commented 8 years ago

Hi, Which eigen version is used? I have errors compiling with 3.2.8 `./tensor.h:39:10: fatal error: 'unsupported/Eigen/CXX11/Tensor' file not found

include <unsupported/Eigen/CXX11/Tensor>`

And after I go to https://github.com/RLovelett/eigen to get the unsupported/eigen/CXX11, there is just too many errors compiling:

on mac, dont use brew install eigen, clone from source directly
