installing edward in anaconda

[neuronphysics]

I have been trying to install tensorflow and edward on my macos laptop and I failed following all the recipes in the web. This is how I installed edward and tensorflow

conda create -n tf_env python=3.6
conda activate tf_env
pip install --ignore-installed --upgrade tensorflow==2.0.0
conda install numpy pyyaml mkl mkl-include setuptools cmake cffi typing
pip install edward

Here I get the following errors when I import edward

>>> import tensorflow
>>> import edward

Any suggestion why did I get this errors?
Thanks

Do you have to use version 2.0.0 of tensorflow?
I'm using edward well with the following version.
tensorflow==1.2.0rc0
