FutureWarning: pandas.util.testing is deprecated

[buunaanaa]

sorry, this is not related to the last problem I had.

#main.ipynb
import pandas as pd
import numpy as np
import os

from pandas import DataFrame
from datetime import datetime
import matplotlib.pyplot as plt

#import pyEX as p
import csv
import requests
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import matplotlib as mpl
%matplotlib inline
from matplotlib.pylab import rcParams
import seaborn as sns
# from talib.abstract import *
# from pandas_datareader import data
import pandas_datareader as dr
import pandas_datareader.data as web

import buunaanaa
x=2
buunaanaa.readbuu(x)

here is the second file:

#buunaanaa.py

def readbuu(x):
    print('111')
    return x

when i add a line into the 2nd part:

#buunaanaa.py

def readbuu(x):
    print('111')
    # after i added next line and save the file, it won't show 222 unless i reseat the kernel 
    print('222')
    return x

after i saved buunaanaa.py and run the code in main.ipynb, it won't show 222 unless i restart the kernel.

at the same time it shows me an error

Error:
D:\programs\Anaconda3\lib\site-packages\pandas_datareader\compat\__init__.py:7: FutureWarning: pandas.util.testing is deprecated. Use the functions in the public API at pandas.testing instead.
  from pandas.util.testing import assert_frame_equal

BTW, I un-install the Anaconda and re-installed it completely after I had issues with old pandas.
