Code stopped working after yesterday's update, please help

Just saw the discussion on how to fix this, thank you!!

Hi,

I love this function and I've been using it for my assignments in jupyter lab. This code used to work before:

import pandas as pd
import dataframe_image as dfi

df = pd.DataFrame({'A': [1,2,3,4],
                   'B':['A','B','C','D']})

dfi.export(df,'red_page.png')

Now I get the below error, could you please help?

Traceback (most recent call last):

  File ~\Anaconda3\lib\site-packages\IPython\core\interactiveshell.py:3397 in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)
