def TFE_ContextOptionsSetAsync(arg1, async):

SyntaxError: invalid syntax

if you use Anaconda, you can use conda install -c hesi_m tensorflow to install tensorflow 1.9.0 for CPU

if you specifically use Keras also, you can use conda install -c hesi_m keras which installs Keras 2.2.0 in accompany with everything including tensorflow 1.9.0

It is better to make a fresh anaconda environment for your experiments

See #17022 and #20517

@lutzroeder refer to the issue #20690.

and find anywhere the variable async is used and replace it with async1 so its not a python 3.7 keyword anymore. you will find those "async" variables on line 114, 115, 154 (for the tf version 1.10.0)
So this (for instance):
def TFE_ContextOptionsSetAsync(arg1, async):
becomes this:
def TFE_ContextOptionsSetAsync(arg1, async1):

This solved my issue!

any update on the issue? I get this error on Windows 8
