We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Nightly build break
**System information**
- TensorFlow version and how it was installed (source or binary): tf-nightly-**2.2.0.dev20200115** 
- TensorFlow-Addons version and how it was installed (source or binary): tfa-nightly-**0.8.0.dev20200115**

**Describe the bug**
Hi, it looks like [this commit](https://github.com/tensorflow/addons/commit/3aae7732998cb233234a2948010b9aaafc24e920) causes the latest nightly build to fail on import

```
----> 1 import tensorflow_addons

/usr/local/lib/python3.6/dist-packages/tensorflow_addons/__init__.py in <module>()
     30 
     31 # Cleanup symbols to avoid polluting namespace.
---> 32 del absolute_import
     33 del division
     34 del print_function

NameError: name 'absolute_import' is not defined
```
