ImportError: cannot import name ‘implements’ from ‘zope.interface’

1. 问题分析

问题原因：
/home/user/.conda/envs/vectornet/lib/python3.8/site-packages/apex/interfaces.py中在使用zope.interace中使用了老表达。

2. 解决办法

原文件内容：

from zope.interface import implements
from zope.interface import Interfaceclass IApex(Interface):""" Class so that we can tell if Apex is installed from other applications"""passclass ApexImplementation(object):""" Class so that we can tell if Apex is installed from other applications"""implements(IApex)

修改为：

# from zope.interface import implements
from zope.interface import implementer
from zope.interface import Interfaceclass IApex(Interface):""" Class so that we can tell if Apex is installed from other applications"""pass@implementer(IApex)
class ApexImplementation(object):""" Class so that we can tell if Apex is installed from other applications"""#implements(IApex)

Error: cannot import name ‘ZopeTransactionExtension’ from ‘zope.sqlalchemy’
同样的问题
原格式

from zope.sqlalchemy import ZopeTransactionExtension
from sqlalchemy.orm import scoped_session, sessionmakerSession = scoped_session(sessionmaker(extension=ZopeTransactionExtension()))

修改为

from zope.sqlalchemy import register
from sqlalchemy.orm import scoped_session, sessionmakersession_factory = sessionmaker()
Session = scoped_session(session_factory)
register(Session)
