Can one mix ops and assets? I have a set of notebooks, some of which produce outputs which feed into the others. My first attempt was to set up dagstermill assets, until i realized there that the asset was the notebook, and not any outputs i want from it. So my next attempt is going to be to use

define_dagstermill_op

with appropriate ins and outs. With

define_dagstermill_asset

I can use

AssetIn

objects in

ins

, can I do that in

define_dagstermill_op

? And what about the

outs

?

Did you check Assets from Graphs? https://docs.dagster.io/concepts/assets/graph-backed-assets#advanced-subsetting-graph-backed-assets

Thank you! Going to go try this now. While the if statement for selective materialization seems wierd, I suspect i can structure the notebooks so as to have them in the "pipeline" python file instead!
