Python 使用spellfix1表反映sqlite数据库

我试图反映一个基于sqlite的数据库（更具体地说是数据库）

我可以连接到数据库：

import sqlalchemy as sa
from sqlalchemy.orm import create_session

from sqlalchemy.ext.automap import automap_base
from sqlalchemy.engine.reflection import Inspector

conn = 'sqlite:////..../com.plexapp.plugins.library.db-2016-07-17'
eng = sa.create_engine(conn)
plex = eng.connect()

我可以查询数据库：

s = create_session(plex)
r = s.execute('SELECT COUNT(*) FROM METADATA_ITEMS')

r.fetchall()

>>> [(55368,)]

我甚至可以用SQLAlchemy的检查员检查所有的表格

i = Inspector.from_engine(plex)
i.get_sorted_table_and_fkc_names()
>>>> [('metadata_item_views', set()),
 ('cloudsync_files', set()),
 ('library_timeline_entries', set()),
 ('synced_ancestor_items', set()),
 ('schema_migrations', set()),
 ('fts4_tag_titles_stat', set()),
 ('spellfix_tag_titles', set()),
 ('metadata_items', set()),
 ('media_streams', set()),
 ('metadata_relations', set()),
 ('play_queue_generators', set()),
 ...

然而，我似乎无法反映整个数据库。我得到了一个丑陋的大例外：

m = sa.MetaData(bind=plex)
m.reflect()
>>>>
