Word2vec basic show id and word together

[hunkim]

When I first read the output, I spent a lot of time to understand these numbers to match them. Now, words along with the ids clearly show what's going on in the sample data and prediction pairs.

[New output]: clearly shows the word ids and corresponding words
Sample data [5239, 3084, 12, 6, 195, 2, 3137, 46, 59, 156] ['anarchism', 'originated', 'as', 'a', 'term', 'of', 'abuse', 'first', 'used', 'against']
3084 originated -> 12 as
3084 originated -> 5239 anarchism
12 as -> 6 a
12 as -> 3084 originated
6 a -> 12 as
6 a -> 195 term
195 term -> 6 a
195 term -> 2 of

[Old output]: No words for Sample data. Word ids and words are mixed, so it's very hard to read
Sample data [5239, 3084, 12, 6, 195, 2, 3137, 46, 59, 156] ['anarchism', 'originated', 'as', 'a', 'term', 'of', 'abuse', 'first', 'used', 'against']
3084 -> 5239
originated -> anarchism
3084 -> 12
originated -> as
12 -> 3084
as -> originated
12 -> 6
as -> a
6 -> 195
a -> term
6 -> 12
a -> as
195 -> 6
term -> a
195 -> 2
term -> of

@vrv Hmm. I am not sure where/how this BR brakes those tests. It was fine in my environment. I'll double check.

[vrv]

no, jenkins broke, we restarted it. let me try again: @tensorflow-jenkins test this please

[vrv]

Jenkins keeps breaking but python3/mac tests passed so this is syntactically fine. Merging.
