Hi Brad,

Are you using pandas 0.20? If so, it looks like this is covered over here:
#304

[behudson]

Yes. It looks like this was fixed in #324 <#324>, but is not available from Continuum Analytics (e.g. "conda install pandas-datareader"), which may be why it still occurs in my environment.

Go to the conda website and search for pandas-datareader. The default is not up to date. Try this:
conda install -c conda-forge pandas-datareader=0.4.0

[behudson]

Thanks for the tip to use conda-forge for this. Version 0.4.0 seems to work for Google, but not Yahoo.

[WBare]

yes, that is a different issue. Yahoo finance just recently shut town the service they were running. There is a way to adapt pandas-datareader to the new method, but I don't know if anyone is taking up that challenge. Check out the issues posted on datareader and you will see if posted a bunch of times.

closing as user issue.
