You could to

  datasets = list(partitioner.generate(dataset))

to get them all at once.

That a look at the datasets. They have a sample attribute 'partition'
(or something like that). Now look at the help for Dataset.summary()
(just do ``ds.summary?`` in IPython). That will list a 'chunks_attr'
arguments that you can set to be the partitions argument. Which in turn
will cause the summary to be per-partition.

Hope that helps,
