Getting NaN after running AI. Is my training data wrong?

[Dec0yyy]

Hello.
My training data looks as follows:

    input: [
      "Sett, Galio, Lee Sin, Miss Fortune, Pyke",
      "Pantheon, Aphelios, Kai'Sa, Fiddlesticks, Jhin",
    ],
    output: [1],

and I'm passing net.run(testData) where testData is
[ "Gwen, Graves, Gragas, Gnar, Jayce", "Darius, Jax, Kayn, Lux, Neeko" ].

Can anyone see why I would be getting NaN as a result?

Thank you.

That only works with a LSTM.
