Adjoint plugin - how can I collect the task_id of the forward and backward runs

[remypa]

Hi,

I am using the adjoint plugin, and I'm looking for the way to collect the task_ids of the forward and backward runs. I would need it to be able to use web.delete to delete the data stored server-side (and avoid paying the corresponding storage fees....).

I could not find any other way than patching tidy3d/plugins/adjoint/web.py to add the task_id to the calls to JaxSimulationData.from_sim_data().

Am I missing the normal / non-hacky way of doing this ?

Thanks

Hi @remypa

I think this is actually an oversight on our part. Probably the task_id should be passed in from_sim_data() but we didn't do so.

is this what you did?

        # construct JaxSimulationData with no data (yet)
        self_dict["simulation"] = jax_sim
        self_dict["data"] = ()
        self_dict["task_id"] = task_id # <- Add this line

I can add this fix for a future version, thanks for bringing this to our attention! You can submit a form here to get some free credits for the bug find :).

actually I think this is not the fix, I needed to pass task_id in to all calls of from_sim_data().. but I'll fix it one way or another in #1674
