What will we cover?
If you use get_data_yahoo from Pandas Datareader and it suddenly stopped working, then we will look at how to fix.
The Error and Problem
Consider this code.
import pandas_datareader as pdr
from datetime import datetime
data = pdr.get_data_yahoo('^GSPC', datetime(1970, 1, 1))
It has been working up until now. But suddenly it writes.
Traceback (most recent call last):

What to do?
The fix
There has been a breaking change and you need to update your Pandas Datareader.
You can upgrade to the newest version as follows.
pip install --upgrade pandas-datareader
It should update it to version 0.10.0 or later.
Then the code should work again.
While using my python script that uses pandas-DataReader v10 & pandas v1.3.3 get_data_yahoo(), when it first starts off it will show the last 5 days correctly because I am tailing this for the last 5 days, then after about a minute or two it changes to what you see below, I am using python 3.7.10 The date moves back 2 weeks and the volume from the last 4 days is off a lot, the current day is always correct ok
I run my script on linux using the “watch -n1
Code below
—————————————–
def get_data(tickers):
df = pdr.get_data_yahoo(tickers)
return df
for df in tickers:
df = get_data(df) # this function retrieve’s stock information from yahoo finance
df = pd.DataFrame(df.Close)
print(df.tail(5)
——————————————–

how can anyone help me
Hi Frank,
It looks like you have a list of Tickers you iterate over. You get the data for all of the and print the last retrieved data.
The line taking Close in a DataFrame is maybe not needed?
What is the goal here? For each iteration see the last five days of the specific ticket?
If you share the list of tickers you are looking at and the full code I can take a look at it.
Please share a bit more what you want to achieve. Iterate over a list of tickers and print last five trading days?
I am getting information for one stock and that is the closing price and volume and I am using pandas-datareader get_data_yahoo() function, when I first run the stock one time it looks like the first photo, but what I am doing is using the “watch -n1 ” to get updates every 1 to 5 seconds so I get live updates, but after some time the data coming back goes back to September 09 2021 – August 31, 2021 like the second photo and the volume numbers don’t make any sense they are going into the billions, I have tried everything, different version of python3 + different versions of pip3 and pandas and pandas-datareader, the question is why does it keep going back to the last two weeks and why is my volume messed up, except for the current day., it only took 6 minutes for it to change to photo two

I think this will do what you want:
import pandas_datareader as pdr
from datetime import datetime, timedelta
while True:
df = pdr.get_data_yahoo('AAPL', datetime.utcnow() - timedelta(days=7))
print(df)
Doesn’t work.

Hi Bob,
Just make sure we have installed in the right environment.
Try to execute:
import pandas_datareader as pdrprint(pdr.__version__)
It should output: 0.10.0
If not, it is not installed (upgraded) in the right environment.
What environment are you using?
I am using Python 2.7 because it is what the author of an instruction video to scrape finance data from yahoo uses but I guess I’m gonna have to upgrade to Python 3 because I only have pandas 0.8.1.
Then you need to update your pandas-datareader.
Are you running the code from a command line or use a IDE like PyCharm?
I am using Spyder. I tried updating pandas but it said I already had the latest version so I guess 0.8.1 is the latest version for Python 2.7.
Ah yes – you need to update the pandas-datareader – see the command how to upgrade in the text above.
Hi, how can I check the version of pandas-datareader? I am using Anaconda distribution. After struggling for hours, I finally figured out how to install pandas-datareader (need to use conda install -c anaconda pandas-datareader in Anaconda Prompt).
However I still get the “Unable to read URL” error. I tried to check the datareader version using “print(dpr.__version__) but it says that there is no attribute ‘__version__’. Please help.
Hi Alex,
If you run this:
import pandas_datareader as pdr
pdr.__version__
In a cell and it does give you no attribute error, then you can run the following in a cell:
!pip freezeThen you need to find the line with
pandas-datareader==0.10.0
It is ordered, so you should be able to locate it. (my output gives it for version 0.10.0, your’s might be different).
Hello Rune, I’m unable to get multiple tickers. It keeps giving me this error

Hi,
Can you please share the tickers (how it is defined).
i have the same error :
ticker = [‘AAPL’]
start = dt.datetime(2020, 1, 1)
data = pdr.get_data_yahoo(ticker, start)
print(data)
ValueError: Index contains duplicate entries, cannot reshape
It should work.
Make sure you have the right formatting.
import pandas_datareader as pdrimport datetime as dt
ticker = ["AAPL"]
start = dt.datetime(2020, 1, 1)
data = pdr.get_data_yahoo(ticker, start)
print(data)
If this does not work – make sure you have the right version of pandas datareader.
Hi Rune , i have the same problem
tickers = [‘AAPL’ ‘MSFT’]
start = dt.datetime(2020, 1, 1)
data = pdr.get_data_yahoo(tickers, start)
print(data)
i i insert tickers ‘ValueError: Index contains duplicate entries, cannot reshape?
but if in tickers i insert ‘GBPUSD=X’, ‘EURGBP=X’ this is ok
See the other reply.
