Long running workers blocking GIL timeout errors
问题 I'm using dask-distributed with a local setup (LocalCluster with 5 workers) on a dask.delayed workload. Most of the work is done by the vtk Python bindings.

When I run the workload, my terminal prints out a bunch of errors like this: Traceback (most recent call last): File "C:\Users\patri\AppData\Local\Continuum\anaconda3\lib\site-packages\distributed\comm\core.py", line 221, in
