No backports error while retraining Tensorflow's Inception v3 model

I have been trying to retrain Inception by following the tutorial here: https://www.tensorflow.org/tutorials/image_retraining. I get this error "No module named backports" when I run this

bazel-bin/tensorflow/examples/image_retraining/retrain --image_dir ~/marine_animal_species1

This is the full Traceback:

Traceback (most recent call last):

    ImportError: No module named backports

I use ubuntu 16.04. Thank you for the help.

sudo pip install backports.weakref
sudo pip3 install backports.weakref

Solved the problem for me.

Install the weakref module from the backports namespace. You can get the wheel file from https://pypi.python.org/pypi/backports.weakref/1.0rc1 & install the downloaded wheel as such:

sudo pip install backports.weakref-1.0rc1-py2-none-any.whl # python2
sudo pip3 install backports.weakref-1.0rc1-py3-none-any.whl # python3

Then run your command

bazel-bin/tensorflow/...

This should solve your problem.
