Same problem here on Ubuntu 16.04 with Python 3.5.
Clearly, Python 3 doesn ' t need futures. And with Python 2.7, using:
pip2 install tensorflow-gpu==1.5.0
It goes well.
Here's a solution for Python 3:
The error is occurred when installing the version of Futures 3.2.0 for Python 3. It's noticed that:

It should not being installed on Python 3, although there should is no harm in doing so, as the standard library takes preced ence over third party libraries.

First, install Futures 3.1.1:

pip3 install futures==3.1.1
Then:
pip3 install tensorflow-gpu==1.5.0
Does not add the --ignore-installed or-I
