-The model to be trained must have a set of tracked parameters that are used to calculate the gradients of the objective function. In the [basics](../models/basics.md) section it is explained how to create models with such parameters. The second argument of the function `Flux.train!` must be an object containing those parameters, which can be obtained from a model `m` as `params(m)`.

 Such an object contains a reference to the model's parameters, not a copy, such that after their training, the model behaves according to their updated values.
