Bug in Metrics DataFrame

[Tsmith5151]

When styling the output metrics dataframe, the following error can be thrown due to threshold rounding.

display(df_to_show.style.background_gradient(cmap = cm).set_table_styles(styles))

ValueError: style is not supported for non-unique indices.

@amirhessam88, this appears to be a rounding issue when naming the dataframe index and changing to 4f should resolve the duplicate indices names.

metrics_df = pd.DataFrame(
            data=self.metrics_dict_,
            index=[
                f"""Threshold = {self.threshold:.3f} | Average =
                {self.average_method.title()}"""
            ],
        )

Just fixed it. It is now follow precision_digits that you can call in the class.
