Fails to export data to R

[pablodegrande]

I am using the library to convert an SPSS file, and conversion fails. I am attaching the file....

test.py

import pandas as pd
import pyreadr

df = pd.read_spss('en.sav')
pyreadr.write_rdata('en.rdata', df, df_name="dataset")

Traceback (most recent call last):
File "D:\Pablo\Sociologia\Mapa Social\poblaciones\services\py\test.py", line 5, in
pyreadr.write_rdata('en.rdata', df, df_name="dataset")
