I got the following error message when I define entity set with featuretools:

AttributeError: 'str' object has no attribute 'copy'

Here's my code:

import featuretools.variable_types as vtype 

es = ft.EntitySet(id="Policy")
es = es.entity_from_dataframe(entity_id="Policy", dataframe='policy_df',index='Policy_no',variable_types={'Policy_no':vtype.Categorical})

Anyone faced same issue before?

The issue appears to be with the argument dataframe='policy_df'. The dataframe should be a Pandas DataFrame object not a string. `
