function or associated item not found in `PyModule`

[bbartling]

Hello,

From the Py03 documentation I am trying out something similar to the example in the calling Python from Rust example 3.4. Executing existing Python code...

I have this setup, am running on Rasbian Linux on rust version rustc 1.75.0:

.
├── Cargo.lock
├── Cargo.toml
├── python_app
│   ├── app.py
│   └── utils
│       └── foo.py
└── src
    └── main.rs

Where my toml file looks like:

[package]
name = "asyncio_tests"
version = "0.1.0"
edition = "2021"

# Cargo.toml dependencies
[dependencies]
pyo3 = { version = "0.20" }
pyo3-asyncio = { version = "0.20" }

app.py:

from utils.foo import bar

async def run():
    result = await bar()
    return result

foo.py:

import asyncio

async def bar():
    await asyncio.sleep(1) 
    return "baz"

Cargo check and build I get this error:

Any ideas to try?
