Hi flyte community! I have a question about the resolver path. I noticed that if I use

pyflyte register

to register the workflow, the resolver path would be

app.<…>.default_task_resolver

, but if programmatically register workflow using

register_workflow()

, the resolver path would be

module.<…>.default_task_resolver

(

module

being the root of the workflow code). Is there a way to change the resolver path back to

app

if I use

register_workflow

can you elaborate a bit more? what is this default_task_resolver?

can you maybe copy paste in a

tree

structure and some sample repro code?

Sorry for the late reply I was distracted yesterday. To be more specific, if I register programmatically using

register_workflow

, and the resolver path would be

run_my_workflow.pip_pypi__flytekit.flytekit.core.python_auto_container.default_task_resolver

. And

run_my_workflow

is the ~~parent directory~~ bazel target name of the script (same as the script name in this case) that calls

register_workflow

And if I register my workflow using CLI

pyflyte register

, the resolver path in the task would look like

app.pip_pypi__flytekit.flytekit.core.python_auto_container.default_task_resolver

So I wonder if I can set the root of the resolver path to

app

when calling

register_workflow

I will come up with a repro in a bit. Thanks for the help in advance!

also are you using conda or pip?

i’m not too familiar with conda

pip, but actually, it’s bazel-pip

I think I figured out how to override the default resolver, just need to override the

location

in the

DefaultTaskResolver

Here is my solution:

Copy code

TASK_RESOLVER_LOCATION = "app.pip_pypi__flytekit.flytekit.core.python_auto_container.default_task_resolver"
class CustomTaskResolver(DefaultTaskResolver):
    def __init__(self, *args, resolver_location = TASK_RESOLVER_LOCATION, **kwargs):
        super().__init__(*args, **kwargs)
        self.resolver_location = resolver_location

    @property
    def location(self) -> str:
        return self.resolver_location
    

@task(task_resolver=CustomTaskResolver())
def my_task(a: int, b: int) -> int:
    return a + b


@task(task_resolver=CustomTaskResolver())
def my_other_task(m: int, n: int) -> int:
    return 2 * (m - n)
