  解决方法:
  1) file "__init__", replace:

  class DBAPISet(ImmutableSet): 
  with 
  class DBAPISet(frozenset)
  2) file "converters.py", remove:
  from sets import BaseSet, Set
  3) file "converters.py", change "Set" by "set" (IMPORTANT: only two places):
  line 48: return set([ i for i in s.split(',') if i ])
  line 128: set: Set2Str,
