Import_table Error in python

I come from DCH in China. I try to import table using Hail hc.import_table command like this:
from hail import *

However, I got an error :
AttributeError: ‘HailContext’ object has no attribute ‘import_table’

Should I need to import other modules or do something else to solve the problem?

Your Hail version is out of date - we changed this interface on Monday with the release of the 0.1 build.

Pull the changes from github and rebuild, and everything should work!

OK. I will change it. Thanks for your reply!
