Hi all, I am trying to set the conda environment for the project as mentioned in installation guide. I have been able to set everything till Build Caffe2. After cloning pytorch, when I run cmake in build I get this summary. In summary it shows CUDA 9.2 and cudnn 7.1.4 and other details like opencv 3.4.0 and so on. But down the line it shows following error

(1) [Could not find a package configuration file provided by "Eigen3" with any of the following names: Eigen3Config.cmake eigen3-config.cmake Add the installation prefix of "Eigen3" to CMAKE_PREFIX_PATH or set "Eigen3_DIR" to a directory containing one of the above files. If "Eigen3" provides a separate development package or SDK, be sure it has been installed.] Here is the summary of cmake ..

But down the line while installing it shows me this warning

pragma message "This message is intended to annoy you enough to update."

However in the summary it showed that cudnn version is 7.1.4.

Lastly, It ends with this error CMakeFiles/Makefile2:1401: recipe for target 'caffe2/CMakeFiles/caffe2_gpu.dir/all' failed make[1]: [caffe2/CMakeFiles/caffe2_gpu.dir/all] Error 2 Makefile:138: recipe for target 'all' failed make: [all] Error 2

Desperately looking for solution.

Thanks

Can you post this in caffe2 github, this is rather a caffe2 compilation issue?
