Experiencing the same issue.

Can you check your package version? Those lines of code should not be in there in 0.0.1.0, which is what is on pypi and in the master of this repo.

When I run pip install anchor_exp, v0.0.0.6 is installed. After running pip install --upgrade anchor_exp I did get v0.0.1.0.

However with this new version I am now getting a new error which I was not getting before for the below code:
explainer = anchor_tabular.AnchorTabularExplainer(['Bad', 'Good'], dfTrain.columns, dfTrain)

The above issue was happening since my data was a DataFrame. After changing it to a numpy array, all worked correctly. Thanks.
