AttributeError: module 'pandas' has no attribute 'expanding_median'

我在使用odps的时候，在读取数据想转化为pandas中的DataFrame类型，但是报错了，不知道是什么情况，按照教材来写的代码。` class Conntect_odps(object):

def __init__(self,access_id,access_key,default_project,end_point=None):
    self.access_id = access_id
    self.access_key = access_key
    self.default_project = default_project
    self.end_point = end_point

def get_connection(self):
    odps = ODPS(self.access_id,self.access_key,self.default_project,self.end_point)
    return odps

def put_data(self):
    odps = self.get_connection()
    project = odps.get_project(self.default_project)
    table = DataFrame(odps.get_table('dw_projects_disease_mark',project=project))
    print(type(table.to_pandas()))

发现问题是因为pandas的版本升级之后，expanding_系列的属性都取消了，所以在执行的时候源码中的compiler.py中使用了这一系列的属性，导致报错。需要把pandas降级到0.17.

0.22 就可以了，这个已经修复了，近期会同步到 Github
