[need help] caffe2 install failture

[YunseokJANG]

I tried to install caffe2 by following https://github.com/facebookresearch/VMZ/blob/master/tutorials/Installation_guide.md this tutorial for two days, but no luck. Especially,

1. I get "Failure" from the following command:

   python -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"

2. when I type the same command in python shell, it seems like GPU is not enabled:

   Python 2.7.12 (default, Nov 12 2018, 14:36:49)
   [GCC 5.4.0 20160609] on linux2
   Type "help", "copyright", "credits" or "license" for more information.
   Automatic lazy-import has been disabled. (to enable: pip install lazy_import)
   >>> from caffe2.python import core
   WARNING:root:This caffe2 python run does not have GPU support. Will run in CPU only mode.
   CRITICAL:root:Cannot load caffe2.python. Error: No module named caffe2_pybind11_state

   also I am not sure about 'caffe2_pybind11_state'.

This is my cmake summary

close this issue. (this error rises when you type

python -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"

this command inside of pytorch folder.
