The problem in your case is that you’ve now included `NNFS.jl` in two different places–once inside `Layers.jl` and again in your main file. Those separate `include()s` have created two completely unrelated modules which happen to have the same name. That’s why it’s important _not_ to include the same file multiple times. Here’s a post with a similar question on avoiding multiple includes that you might find helpful: [Need to include one file multiple times, how to avoid warning - #5 by rdeits](https://discourse.julialang.org/t/need-to-include-one-file-multiple-times-how-to-avoid-warning/27439/5)

In your case, you should be able to replace:

```julia
include("NNFS.jl")
import .NNFS: forward

```

with

```julia
import ..NNFS: forward

```

in `Layers.jl`
