Error in notebook Section 4 - Encrypted Deep Learning

[MarksASP95]

I'm running this on a Google Colab with:

Tensorflow: 1.15.0rc3
Syft: 0.1.29a1
Numpy: 1.16.5

Problem is on this specific line:

model.share(alice, bob, carol)

This is the error I'm getting:

TypeError                                 Traceback (most recent call last)
<ipython-input-14-5b486064ddb2> in <module>()
----> 1 model.share(alice, bob, carol)

TypeError: share() takes from 2 to 3 positional arguments but 4 were given

I'm having a similar issue on Section 4b. But that should be another another post.
