NotImplementedError

Hi, I'm getting this error when I try to execute the line before the last one (when we assing the data to the variable PG):

NotImplementedError                       Traceback (most recent call last)
~\AppData\Local\Temp\ipykernel_5556\1473850925.py in <module>
----> 1 PG = wb.DataReader('PG', data_source='Yahoo', start='1995-1-1')

    206                         f"or {repr(new_arg_name)}, not both."
--> 207                     )
    208                     raise TypeError(msg)
    209                 kwargs[new_arg_name] = new_arg_value

~\anaconda3\lib\site-packages\pandas_datareader\data.py in DataReader(name, data_source, start, end, retry_count, pause, session, api_key)

    366         msg = "data_source=%r is not implemented" % data_source
--> 367         raise NotImplementedError(msg)
    368 
    369     if data_source == "yahoo":

NotImplementedError: data_source='Yahoo' is not implemented

PD: My code is exactly the same as the one in the video. I also updated the pandas in the Anaconda's prompt, but didn't work. I also ty another code (import yfinance as yfin
yfin.pdr_override()) and that also didn't work, with that alternative code I got: ModuleNotFoundError: No module named 'yfinance'

Please help me.
