Help for Beginner using Edward

I am new to using Edward. I am trying to do the tutorials but I have noticed that two kinds of errors exist despite importing the correct libraries.

ImportError: cannot import name ‘set_shapes_for_outputs’

ImportError: ed not defined.

Please , what can I do ? My Tensorflow version is 1.12.0 and edward 1.3.5. I really appreciate any help I can get on this. Thanks.

I got the same errors at the beginning and try to install different version of Tensorflow and Edward. The latest version that works for me is Tensorflow 1.6.0 and Edward 1.3.5.
