DataCore/dataserver/api/py/data_api.py 出错

[bn888]

DataCore/dataserver/api/py/data_api.py 出错：

ValueError: Attempted relative import in non-package

此data_api 与 jaqs.data.DataApi 是否相同？dataserver1.2 到底用哪一个呢？

但是用 jaqs.data.DataApi 也同样出错：
api=DataApi("tcp://0.0.0.0:8910",use_jrpc=True)
runfile('D:/dataserver-1.2/dataserver/data_api.py', wdir='D:/dataserver-1.2/dataserver')

C:\Anaconda2\lib\site-packages\dateutil\parser.py:605: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
elif res.tzname and res.tzname in time.tzname:
Kernel died, restarting
请问是什么问题呢？
