Before trying to update tensorflow try updating pip
pip install --upgrade pip
If you are upgrading from a previous installation of TensorFlow < 0.7.1, you should uninstall the previous TensorFlow and protobuf using,
pip uninstall tensorflow
to make sure you get a clean installation of the updated protobuf dependency.
Uninstall the TensorFlow on your system, and check out Download and Setup to reinstall again.
If you are using pip install, go check the available version over https://storage.googleapis.com/tensorflow, search keywords with linux/cpu/tensorflow to see the availabilities.
Then, set the path for download and execute in sudo.
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.0.0-py2-none-any.whl
$ sudo pip install --upgrade $TF_BINARY_URL
