func was renamed to fget in #43828 (since 1.4) to be more consistent with python's property. I assume that the external pandas packages you are importing pandas_datareader and/or pyfinance haven't yet been tested against pandas 1.4. Unfortunately, I forgot to add a whatsnewentry for this change in #43828.

It appears that this an downstream issue in the packages mentioned since those libraries are using private APIs so they can be subject to change. I would recommend opening up an issue in the libraries you used to address the pandas usages.

After reinstalling a fresh virtual env with the latest version of statsmodels, I solved the problem. I noticed though that the latest version of statsmodel is not available on the conda channels.

Thanks for your help!
