Hi Guys,
I am trying to install pytorch from source because of this (glibc version) issue https://github.com/pytorch/pytorch/issues/6607 15
Below are the commands I used :
$export CMAKE_PREFIX_PATH=/home/jamess/anaconda2/ [#anaconda path]
$conda install numpy pyyaml mkl mkl-include setuptools cmake cffi typing
$conda install -c mingfeima mkldnn
$git clone --recursive https://github.com/pytorch/pytorch
cd pytorch
$python setup.py install
System info :
OS : CentOS release 6.7
CUDA : N/A
I get the following error :

CMake Warning at cmake/Dependencies.cmake:310 (find_package):
By not providing “FindEigen3.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “Eigen3”, but
CMake did not find one.

provides a separate development package or SDK, be sure it has been
installed.
