Save DataFrame to csv encounters error “ImportError: cannot import name ‘StringIO'”

I have a pandas DataFrame output_df that I can manipulate or print without problems. However, when I run output_df.to_csv(output_filename), it gives an error:

  File "my_file.py", line 169, in run_attribute_generator
    output_df.to_csv(output_filename)
  File "/usr/local/lib/python3.6/site-packages/pandas/core/generic.py", line 3204, in to_csv
    New Series or DataFrame with updated labels.
  File "/usr/local/lib/python3.6/site-packages/pandas/io/formats/csvs.py", line 17, in <module>
    from pandas.compat import (StringIO, range, zip)
ImportError: cannot import name 'StringIO'

My pandas version is 0.25.1

It seems that you have to downgrade your pandas version to 0.24.2 or lower. Hope it helps
