tensorflow1.4.0 not support python3.7,you need install python 3.6 in virtualenv or conda

[villemikkola]

You can install tensorflow and other requirements separately with pip or just change the version requirements in the file to also match newer versions. So change tensorflow===1.4.0 to tensorflow>==1.4.0 and so on. At least the version 1.13.0 seems to work just fine.

For Mac OS X Mojave 10.14.6 (18G87).
pip 19.2.3 (python 3.7)

requirements.txt:

Keras==2.1.2
tensorflow==1.14.0
nltk==3.2.5
opencv-python==4.0.0.21
numpy==1.17.1
h5py==2.9.0
matplotlib==2.0.2
Pillow==6.1.0
tqdm==4.17.1
scipy==1.3.1

And then pip install -r requirements.txt

UPD: Probably need to install brew install pkg-config before python packages.

I installed Python 3.6 (64 bit) and it worked fine. Any larger version (3.7, ...) fails sooner or later. Also there was need for 64 bit version, not 32 bit.
