Cannot import tensorflow in python after source build

Question

I am trying to install tensorflow with cuda and cudnn on a linux machine. I do not have sudo access, so I am building from source. I followed instructions here: https://www.tensorflow.org/versions/master/get_started/os_setup.html#source

I got till the part where we get lots of output:

This tutorial iteratively calculates the major eigenvalue of a 2x2 matrix, on GPU.
The last few lines look like this.
000009/000005 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]
000006/000001 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]

But after that, when I open python and try to import tensorflow, it says there is no such module.

Thanks in advance.

Also, I do not understand why we are building only the example_trainer in this line: bazel build -c opt --config=cuda //tensorflow/cc:tutorials_example_trainer Shouldn't we build the whole package? — abora

You need to take a few more steps before you can import TensorFlow in a Python shell: just building //tensorflow/cc:tutorials_example_trainer does not build any of the Python front-end.

The easiest way to do this from a source installation is to follow the instructions for building a PIP package from source, and then installing it (either globally on your machine, or in a virtualenv).

The anchor in the link is dead. Here's a new one tensorflow.org/versions/master/get_started/… (comment edited)
