, you'd use from . import config
if config
is in the same directory, or from .. import config
if it's one level up, and so on.
If you're still having trouble, you could try packaging your utility modules and installing them in the same environment where you're deploying your flow. It's a bit more work, but then, what isn't?

module, like so:
python
import sys
sys.path.append('..')
This tells Python to also look in the parent directory when resolving imports. It's a bit like giving Python a map when it's lost. Not that Python would ever admit to being lost, of course.

, it looks in your working directory for all flows and presents them for deployment. If you specify an entrypoint directly in the CLI, like prefect deploy my_flow.py:my_flow
, it will look for my_flow.py
in your working directory.
However, if you move your entrypoint file and run prefect deploy
again, you might run into issues. The flows.json
file in the ~/.prefect
directory could end up with an incorrect absolute value, which can be tricky to debug.
So, in short, yes, Prefect does assume that your entrypoint flow is in the root directory. It's a bit like a homing pigeon, always returning to the same spot. Except when it doesn't, of course.

, that should work just fine.
When you run prefect deploy
, you'll need to specify the path to your entrypoint flow. So, in your case, you'd run something like prefect deploy config/start_flow.py:my_flow
, where my_flow
is the name of the flow you're deploying.

, is Python's way of telling you that it can't find the module you're trying to import. This usually happens when you're trying to import a module from a parent directory, which Python doesn't allow by default.
In Prefect, when you're deploying a flow, the entrypoint script is loaded as a module. This means that all the imports in the script need to be resolvable from the script's location. If you're using relative imports that go beyond the top-level package, Python will raise an error.
One way to solve this problem might be to restructure your project so that you don't need to use relative imports that go beyond the top-level package. This might involve some refactoring, but it could make your project easier to manage in the long run.
Alternatively, you could try using absolute imports instead of relative ones. This would involve specifying the full path to the module you're importing, starting from the top-level package. For example, instead of from .. import config
, you'd use from my_project.config import config
.

). This is likely what's causing the attempted relative import beyond top-level package
error.
