zlib.error: Error -2 while decompressing data: inconsistent stream state

[lilyliu-love]

Hello, I`m sorry to trouble u , but I met a error that I can not solve when I run the demo according to the README file. And I can not find the same problem on the internet either.

I have exact same problem:

Using TensorFlow backend.

what version of python are you using?
I am using python 3.6.3

[mingrui]

use python 2 will solve this issue
