zlisto / Daily-Fantasy-Baseball-Contests-in-DraftKings

This is the code for constructing a portfolio of lineups for DraftKings baseball contests with a top heavy payoff structure. This code is based on the paper Picking Winners Using Integer Programming by David Hunter, Juan Pablo Vielma, and Tauhid Zaman (https://arxiv.org/abs/1604.01455).

Can anyone help me with this error? Full text below, and Line 44 string beneath:

It looks like your inputs to create_lineups are off and the solver can't work with the data. It's really hard to tell though. Try looking at your inputs before they go into create_lineups() and make sure that they are as they should be.
