Need to change module versions setup.py in order to run precise

[TheRealDGD]

Describe the bug
To get an working version of precise you have to modify setup.py and change/force some module versions

    install_requires=[
        'numpy==1.16',
        'tensorflow>=1.13.0,<1.14',  # Must be on piwheels + match URL in setup.sh
        ..
        'keras<=2.1.5',
        'h5py<3.0.0',
        #'typing',
    ],

To Reproduce

git clone --branch master https://github.com/mycroftai/mycroft-precise
cd mycroft-precise
./setup.sh

ERROR: No matching distribution found for tensorflow==1.8.0

Expected behavior
setup should be working without modifying setup.py
Is there a reason not to change setup.py in the repository?
