Description:
 def sync_imports( self, quiet = False ):
 """Return a context manager to control imports onto all the engines in the underlying cluster. This method is used within a ``with`` statement. Any imports should be done with no experiments running, otherwise the method will block until the cluster is quiet. Generally imports will be one of the first things done when connecting to a cluster. (But be careful not to accidentally try to re-import if re-connecting to a running cluster.) :param quiet: if True, suppresses messages (defaults to False) :returns: a context manager"""
