List volumes block_store call error

[chenyb4]

When i use python-openstacksdk call block_storage service appear block_store error. the error message look this.
ceback (most recent call last):
  File "connection_cluster.py", line 52, in <module>
    volume_list(conn)
  File "connection_cluster.py", line 49, in volume_list
    v = conn.block_store.volumes()
AttributeError: 'Connection' object has no attribute 'block_store'

When i use pdb test, the 'LOCAL_ALIASES' define error.
Pdb) p service_type
u'block-storage'
(Pdb) p LOCAL_ALIASES
{'baremetal': 'bare_metal', 'block_storage': 'block_store', 'clustering': 'cluster'}

The service_type is 'block-storage', but in LOCAL_ALIASES use block_storage, so this is LOCAL_ALIASES error.
