Hi,

I am trying to import a dictionary that I saved in python with the extension .jld2  
First, I tried this code to do that:

```julia
> using JSON
> using DataStructures
> using JLD2
> dict_name = load("path/dict_name.jld2")

```

And, throw me this error:

`UndefVarError: load not defined`

Then, I tried with this:

```julia
> using JSON
> using DataStructures
> using JLD2
> dict_name = @load "path/dict_name.jld2" 

```

But it is imported as an array object.

**Could you help me with the correct code to import it as a dictionary?**

Simply changing the extension won’t give you a proper JLD2 file.

how did you create a JLD2 file from python? JLD2 is a julia pkg
