Package 0.5.1 against TF2-RC1

[seanpmorgan]

Looks like RC1 was released. We were already planning the next minor release so should probably build against this version.

Thanks for reminding me, Sean. Totally agree.

I suggest that we should make correlation_cost private, see #509 . I'm happy to release 0.5.1 after finishing it. What do you think?

Release looks great... thanks Yan!

@seanpmorgan Sean, I find there seems something wrong when using in linux cpu environment.

$ pip install tensorflow-addons==0.5.1
$ python

>>> import tensorflow_addons as tfa

@guillaumekln reported the bug in #532

[seanpmorgan]

I think that's a good idea. I don't see a reason to not use rc1 and just not pin it using setup.py though. However, seeing as rc2 is coming soon whatever is easiest to rollback and release is good with me

[seanpmorgan]

Think we'll have to fix this on the next minor release. Closing.
