Jupyter - Import Custom Mojo Modules?

How can we import and use a custom Mojo module from a Jupyter notebook? I added details of what I've tried so far by replying to an existing post started by @hogepodge. Thanks! Here's a link to that post: https://discord.com/channels/1087530497313357884/1119100298456215572/1198684128091058198

So I think I have some VS Code weirdness going on, and maybe an issue with Mojo version 0.6.1. With the Jupyter notebook open, VS Code highlighted the import statement saying it was unable to locate module 'my_name', so I prefixed it with the current folder shared.my_name which made the type checker happy but gave an error when I tried to run the Mojo code. I removed the extra shared. and it now runs as expected. Perhaps also important...I updated to Mojo version 0.6.3 Hope this helps anyone else trying to import custom modules in a Jupyter notebook. Cheers...EzRyder Edit: In VS Code, I found that I needed to restart the kernel in order for changes in a Mojo module to propagate into the open Jupyter file. Module: my_name.mojo

struct MyName(Stringable):
    var name: String

    fn __init__(inout self, name: String):
        self.name = name

    fn __str__(self) -> String:
        return str(self.name)

struct MyName(Stringable):
    var name: String

    fn __init__(inout self, name: String):
        self.name = name

    fn __str__(self) -> String:
        return str(self.name)

Jupyter

from my_name import MyName

let username = "Bob"
let name = MyName(username)
print("Hi " + str(name) + "!")

from my_name import MyName

let username = "Bob"
let name = MyName(username)
print("Hi " + str(name) + "!")

Output: Hi Bob!
