Dear Julia friends,

First of all, I apologize for my poor English skills. I have a problem developing a module that uses Embeddings.jl:

```julia
module Portal
include("./t.jl")
export get_embedding
end # module Portal

```

```julia
using Embeddings
const embtable = load_embeddings(FastText_Text{:de})
const get_word_index = Dict(word => i for (i, word) in enumerate(embtable.vocab))

function get_embedding(word)
    ind = get_word_index[word]
    emb = embtable.embeddings[:,ind]
    return emb
end

```

When using Portal I get the following error messages:  
julia\> using Pkg

julia\> Pkg.activate(“.”)  
Activating project at `~/JuliaProjects/Portal`

julia\> using Revise

julia\> using Portal

Some type information was truncated. Use `show(err)` to see complete types.

But if I include the file and then call the method, it works.

```julia
julia> include("./src/t.jl")
get_embedding (generic function with 1 method)

julia> get_embedding("Buch")
300-element Vector{Float32}:
 -0.0781
 -0.0145
  ⋮

```

Thank you in advance for any tips or solutions.

Hi Fahim,

Welcome to the Julia community!

On Windows 10 I get a (presumably) somewhat similar issue:

```julia-repl
julia> using Portal
ERROR: Error opening package file (...)\.julia\compiled\v1.11\Portal\bI5Dh_Imu6F.dll: %1 is not a valid Win32 application.

```

Looking at the file in question, it is about 2.5 GB in size. It then seems likely that the precompiled files can be at most 2^{31} - 1 bytes (`typemax(Int32) == 2147483647`) for 32-bit compatibility. In this case the two `const`s (in particular `embtable`) will be too large to cache.

One option would be to disable precompilation by adding ` __precompile__ (false)` to `Portal.jl`. Or (and a bit better) you could use Preferences.jl to [achieve the same](https://julialang.github.io/PrecompileTools.jl/stable/#Package-developers:-reducing-the-cost-of-precompilation-during-development). The downside is obviously that when `using Portal` you’ll need to compute `embtable` and `get_word_index`, which at least on my pc takes quite a while (for some reason). I suppose you could just manually save and load `embtable.embeddings` and `get_word_index` to and from disk.

Thank you for the welcome and support.

FYI:  
it now works by calling the function **precompile** (false). But the following exception is thrown:  
exception = Error when precompiling module, potentially caused by a **precompile** (false) declaration in the module

Best regards

Yeah, it seems that ` __precompile__ (false)` disables/interrupts precompilation by making it throw an exception. With the Preferences.jl approach you can get rid of this (minor) annoyance.
