Unable to create a databunch

Hello :slight_smile:
I am trying to create a databunch from a dataframe by the following code.

src = ImageList.from_df(df1, destw).split_by_rand_pct(0.2).label_from_df(label_delim = " ")

the data frame looks like this

I am getting an error that argument 1 must be an iterator.

Any help will be appreciated.
