    Fix get_data_yahoo from Pandas Datareader

    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.

    UPDATE: We will also cover a FIX of the current issue in 2023

    Current 2023 ISSUE and FIX

    If you get an error that ends with.

    TypeError: string indices must be integers

    You get that because there has been breaking changes at Yahoo! Finance.

    An easy workaround is as follows.

    Install yfinance.

    pip install yfinance

    Then this code will work (NOTICE the .data in the import from pandas_datareader.data).

    import pandas_datareader.data as pdr
    import yfinance as yf
    from datetime import datetime
    data = pdr.get_data_yahoo('^GSPC', datetime(1970, 1, 1))

    The above code should work.

    Below you have the full error trace.

    Consider this code.

    What to do?

    The fix (old 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.

    1. 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)

      #1 — works correctly Close
      Date Close
      2021-08-15 11.2500
      2021-09-16 9.9600
      2021-09-17 11.0600
      2021-09-20 11.7300
      2021-09-21 13.7001

      #2 — doesn’t work correctly Close

      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.

    2. 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))

      • Hi Bob,
        Just make sure we have installed in the right environment.

        Try to execute:
        import pandas_datareader as pdr

        It should output: 0.10.0

        If not, it is not installed (upgraded) in the right environment.

        What environment are you using?

    3. 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.

    4. 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.

    5. 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

        In a cell and it does give you no attribute error, then you can run the following in a cell:

        !pip freeze
        Then you need to find the line with


        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).

      data = pdr.get_data_yahoo(ticker, start)

      • It should work.
        Make sure you have the right formatting.

        import pandas_datareader as pdr
        import datetime as dt

        ticker = ["AAPL"]
        start = dt.datetime(2020, 1, 1)
        data = pdr.get_data_yahoo(ticker, start)

        If this does not work – make sure you have the right version of pandas datareader.

    8. Hi Rune , i have the same problem

      tickers = [‘AAPL’ ‘MSFT’]
      start = dt.datetime(2020, 1, 1)
      data = pdr.get_data_yahoo(tickers, start)


      i i insert tickers ‘ValueError: Index contains duplicate entries, cannot reshape?

      but if in tickers i insert ‘GBPUSD=X’, ‘EURGBP=X’ this is ok
