Hi everyone.
How to define dependencies for `AssetDefinitions.from_graph`?
Suppose that I have An asset `Asset1` which has key `AssetKey("prefix", "asset1")`  and `Asset2` which has key `AssetKey("prefix", "asset2")`. And a graph `GraphX` , how can I use `AssetDefinitions.from_graph(GraphX,…)` to depends on `Asset1`  and `Asset2`.

One note that we don’t want the `GraphX` to have upstream dependencies. We only want the asset constructed from `GraphX` to have upstream dependencies. I don’t know if it is possible.

This is not currently possible unfortunately - all dependencies must correspond to an input on the actual graph. It's a reasonable request though, so made an issue to track it <https://github.com/dagster-io/dagster/issues/8712>
