Seeing this, too: ``` File "/scratch/develop/venv/lib/python3.9/site-packages/distributed/protocol/serialize.py", line 379, in serialize raise TypeError(msg, str_x) from exc TypeError: ('Could not serialize object of type HighLevelGraph', '') ``` dask/distributed versions are 2024.2.0

My problem was solved by downgrading dask/distributed to version 2023.3.2, the version before the big change in the way how HighLevelGraphs are serialized. All versions after and including 2023.4.0 fail...

Sorry, I still see the error, even with dask/distributed 2024.2.1 ``` 2024-03-28 22:15:16,208 - distributed.protocol.core - CRITICAL - Failed to Serialize Traceback (most recent call last): File "/scratch/focht/Issue_xgb_task_graph/venv-dasknew/lib/python3.10/site-packages/distributed/protocol/core.py", line 109,...
