Import error after compiling from source

Describe the Issue

After installing Tensorflow from source I try to import it by typing: "python3" and then "import tensorflow as tf" which results in an error.

Steps to Reproduce

Followed the step-by-step guide by building from source. In the configure file I changed to python3 and library path 3.4. As well as using Bazel 0.8.

Hardware/Software Info

Raspberry Pi model: Pi 2 Model B v1.1
Operating System used: Raspian GNU/Linux version 8 (jessie)
Version of Python used: 3.4.2
SD card memory size: 16GB
Size of USB/other device used as swap (if building from source): 16GB
TensorFlow git commit hash (if building from source): 56422034fe039d7e8a57392957ed0c8b4b4efe56

#133 same issue

Same here.

The fix for me was to compile TF r1.4 instead. It’s working perfectly fine.

How do you do that?

The same problem here (RPi 3 with Ubuntu MATE). Happens with both tensorflow 1.7 and 1.6 for both Python 2.7 and 3.5. I'll keep trying with lower versions of TF - 1.5 and 1.4.

EDIT: Tensorflow 1.5 with Python 3.5.2 works! Finally successful import.
