I was going through this Flux.jl tutorial and came across something called Chain.
m = Chain(Dense(10, 5, relu), Dense(5, 2), softmax)
It was not imported from any of the used modules and no namespace was used, so I did not know which module it belonged to. Although I managed to find that I belongs to Flux package, I wonder if there is a general way of figuring this out within the script.
To figure out where a specific function comes from, you can use the parentmodule function:
julia> parentmodule(Chain)
Flux
