Error exporting styled dataframes to image-CodePudding

I've been using dataframe_image for a while and have had great results so far. Last week, out of a sudden, all my code containing the method dfi.export() stopped working with this error as an output

raise SyntaxError("not a PNG file")

File <string>
SyntaxError: not a PNG file

I can export the images passing the argument table_conversion='matplotlib' but they do not come out styled...

This is my code:

now = str(datetime.now())
filename = ("Extracciones-" now[0:10] ".png")

df_styled = DATAFINAL.reset_index(drop=True).style.apply(highlight_rows, axis=1)

dfi.export(df_styled, filename,max_rows=-1)

IMAGEN = Image.open(filename)
IMAGEN.show()

Any clues on why this just suddenly stopped working? Or any ideas to export dataframes as images (not using html)?

These were the outputs i used to get: fully styled dataframe images

and this is the only thing I can get right now

Thank you in advance

I had the same issue, and we finally figured it out; looks like the new release of dataframe_image on 1/14 broke something on the previous version. We upgraded the package and the issue was resolved.

pip install -u dataframe_image
