.rhymes file not getting rhymes

[joeycurnutt]

I modified some of the code to work (as this repo hasn't been updated in a while), and the training/generating works, other than the fact that the rhymes aren't saved and therefore the final rap doesn't rhyme. Granted, I am using 16000 lines of Eminem's discography, so that may be the issue. Thanks in advance anyone who can help.
