Description
When attempting to export a dataframe to a Stata data file, I hit the following error due to my dataframe including variables of the Int64 dtype.
import pandas as pd
# CREATE DATAFRAME
s1 = pd.Series(2**33, dtype='Int64')
s2 = pd.Series("ABC", dtype=object)
df = pd.DataFrame({'col1': s1, 'col2': s2})
df = df.append({'col1': None, 'col2': "DEF"}, ignore_index=True)
# EXPORT TO STATA
df.to_stata('df.dta', version=117)Error message:
NotImplementedError: Data type Int64 not supported.
My expectation is columns of dtype Int64 (i.e., a nullible INT) would end up as byte, int or float in the dta file depending on values therein.
Output of pd.show_versions()
