How can I specify a non_argument_dep for a graph_asset

To specify non-argument dependencies for a

graph_asset

, you can use the

ins

parameter of the

@graph_asset

decorator to map input names to

AssetIn

objects that specify the dependencies. The

AssetIn

object can be configured with

dagster_type=Nothing

, indicating that the asset does not expect a runtime value but does have a dependency on another asset. Here's an example from the documentation that demonstrates how to specify dependencies for a `graph_asset`:

python from dagster import graph_asset, asset, AssetIn, op, Nothing, In  @asset def upstream():     ...  @op(ins={"upstream": In(Nothing)}) def my_op():     return ...  @graph_asset(     ins={"upstream": AssetIn(dagster_type=Nothing)}, ) def my_graph_asset(upstream):     return my_op(upstream)

In this example,

my_graph_asset

has a non-argument dependency on the

upstream

asset. The

upstream

input to the

my_graph_asset

function is mapped to an

AssetIn

with

dagster_type=Nothing

, which establishes the dependency without passing a runtime value.
