tqsdk2不支持TqReplay?

from tqsdk2 import TqReplay
Traceback (most recent call last):

File “<ipython-input-1-761000bbddc4>”, line 1, in <module>
from tqsdk2 import TqReplay

ImportError: cannot import name ‘TqReplay’ from ‘tqsdk2’ (C:\ProgramData\Anaconda3\lib\site-packages\tqsdk2\__init__.py)

如果是不支持，请问什么时候可以支持？
