I needed to make change to the following package in order to make it work with the current version of pandas.
https://github.com/sawadyrr5/UfoDataReader
vim /anaconda3/envs/gf/lib/python3.6/site-packages/pandas_datareader/fred.py
Added following
import pandas as pd
pd.core.common.is_list_like = pd.api.types.is_list_like
#from pandas.core.common import is_list_like
