Downgraded dask and distributed to match cluster, but now getting this error:

client = Client('...')

I tried downgrading tornado, but no version seemed to fix the error.

I suspect that your ~/.dask/config.yaml file was written by a more recent version of dask. Try deleting it and see if that resolves the problem.

That worked. Thanks.
