I am following this link: https://dagster.slack.com/archives/C01U954MEER/p1643336322430609 I am trying to use the example that you are discussing, but I am getting this message: "InputDefinition" is not defined" I am using dagster 1.0.3. My goal is try to create graph dependencies

from dagster import job, op, Nothing, In, graph

@op
def op1(context) -> Nothing:
    <http://context.log.info|context.log.info>("op1")
    return

@op(ins={"start": In(Nothing)})
def op2(context) -> Nothing:
    <http://context.log.info|context.log.info>("op2")
    return

@op(
	ins={"x": In(Nothing), "y": In(Nothing)}
)
def op3(context) -> Nothing:
    <http://context.log.info|context.log.info>("op3")
    return

@graph
def graph1() -> Nothing:
    return op2(op1())

@graph
def graph2() -> Nothing:
    return op2(op1())

@graph(
	input_defs=[
		InputDefinition("x", Nothing),
		InputDefinition("y", Nothing)
	]
)
def graph3(x: Nothing, y: Nothing) -> Nothing:
    return op3(x=x, y=y)

@job
def main():
    graph3(
        graph1(),
        graph2(),
    )

Hi @Saul Burgos

InputDefinition

is deprecated as of 1.0, but there is a known bug with graphs. We have an issue to track this and it should be out in this week's release https://github.com/dagster-io/dagster/issues/9531 After this fix gets released you'll be able to use

In

instead of

InputDefinition

Thanks

@chris do you have a code example of the correct syntax now that the update has gone through?

This is what I am trying to do and I am getting this error: "_@graph 'graph3' has unmapped input 'x'. Remove it or pass it to the appropriate op/graph invocation._" If I removed the x,y , I got this: "_@graph 'graph3' decorated function does not have parameter(s) 'y, 'x', which are in provided input_defs. @graph decorated functions should only have keyword arguments that match input names and, if system information is required, a first positional parameter named 'context'_."

@op
def op1(context) -> Nothing:
    print("op1")
    return

@op(ins={"start": In(Nothing)})
def op2(context) -> Nothing:
    print("op2")
    return

@graph()
def graph1() -> Nothing:
    op2(op1())
    return

@graph()
def graph2() -> Nothing:
    op2(op1())
    return

@graph(
    ins={"x": GraphIn(), "y": GraphIn()}
)
def graph3(x, y) -> Nothing:
    pass

@job
def the_job():
    graph3(
        graph1(),
        graph2(),
    )


@repository
def core_generic():
	definitions = [
		the_job
	]
	return definitions

@sandy i remembered chris was on PTO so i played around with this code snippet for a while and couldn't quite get it to work with the nothing dependencies into graph3. do you know what the right syntax is?

hey @Saul Burgos - I would expect your original snippet to work if you take out these lines:

input_defs=[
		InputDefinition("x", Nothing),
		InputDefinition("y", Nothing)
	]

if that doesn't work, what error are you hitting?

@sandy please the new code I am using. in one of my replies , I am not using anymore "InputDefinition" Also I have added the error that I am getting, is the comment number 4
