Note that, by default, `train!` only loops over the data once (a single "epoch").
A convenient way to run multiple epochs from the REPL is provided by `@epochs`.
```julia
julia> using Flux: @epochs
julia> @epochs 2 println("hello")
INFO: Epoch 1
hello
INFO: Epoch 2
hello
julia> @epochs 2 Flux.train!(...)

## Callbacks ## Callbacks
`train!` takes an additional argument, `cb`, that's used for callbacks so that you can observe the training process. For example: `train!` takes an additional argument, `cb`, that's used for callbacks so that you can observe the training process. For example:
