Greetings! I created a package `ModelUtils`

and hope to run it in multiple workers. In this package, a function called `linear_regression`

being exported. The module is under `src`

folder and has the following content

```
module ModelUtils
export linear_regression
include("linear_models.jl")
end
```

In `main.jl`

file where I would invoke the `linear_models`

```
using Distributed
addprocs(exeflags="--project") # the --project flags is essentially running ] activate .
@everywhere using ModelUtils
fn_arg = rand(Float64, (5,2))
@sync for i in 1:nworkers()
@spawnat i linear_regression(fn_arg)
end
```

I would get the following error

`UndefVarError: linear_regression not defined`

What is the cause for this error? Thank you.
