BSON error when used to load weights in module / package

[Ayushk4]

I am trying something like the following and the error I get is ERROR: UndefVarError: Tracker not defined

Steps to replicate this -

1. Let ExampleModule.jl file be the following

module ExampleModule
   using BSON, Tracker, Flux
   include("./file1.jl")
end

2. And here is the code in file1.jl

function load_weights(path) # Loading weights
    c = BSON.load(path)
    return c
end

3. Create and save weights like using Flux; using BSON: @save;, w = param(rand(2,2)) and then @save "wt.bson" w.
4. In a new REPL session , if I do the following -

julia> include("ExampleModule.jl")

julia> ExampleModule.load_weights("wt.bson")
ERROR: UndefVarError: Tracker not defined

It throws an error. The same thing happens if w in step 3. is replaced by Flux.Conv as well.
Also if I do using Tracker, Flux at the top level (i.e. in REPL session - step 4.) this starts working fine. Exporting Tracker and Flux also work fine, except for the tests.

The above example is a simplified version to recreate the error I am facing in JuliaText/TextAnalysis.jl#167

Other Info

Flux v0.8.3
BSON v0.2.3
Julia 1.0.3
OS - Ubuntu 18.04.2 LTS - 64-bit although with Travis CI, doesn't work on osx.

From the looks of it, BSON searches for Tracker and Flux at the topmost level. Am I missing something here?
