Based on your situation, there are a couple of approaches you can use to handle this directory structure issue: 1. The most elegant solution is to use Prefect's

tmpchdir

utility. Here's how you can modify your flow code:

python
from prefect.utilities.filesystem import tmpchdir
import os

# Your flow definition
@flow
def your_flow():
    # Get the parent directory of the current script
    parent_dir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    
    # Temporarily change to the parent directory where project.toml lives
    with tmpchdir(parent_dir):
        # Your flow logic here
        # Any operations in this block will use the parent directory as working directory
        pass

2. Alternatively, you can explicitly specify the project directory when deploying your flow using the

project_dir

parameter:

python
from prefect import flow
import os

@flow
def your_flow():
    pass

if __name__ == "__main__":
    # Get the parent directory where project.toml lives
    project_dir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    
    your_flow.from_source(
        source=".",
        project_dir=project_dir
    ).deploy(
        name="your-deployment",
        work_pool_name="your-pool"
    )

The

project_dir

parameter tells Prefect where to look for the

project.toml

file during deployment creation. Both approaches allow you to keep your flow scripts in subdirectories while still properly referencing the project configuration in the parent directory. The first approach with

tmpchdir

is particularly useful when you need to maintain this directory context during flow execution, while the second approach focuses on deployment creation. Remember that paths in your flow code should be relative to wherever the

project.toml

file is located, as this becomes the effective root of your project.
