FixedFormatter / FixedLocator error with example code

[Sanney146]

Hello,

I am trying to run the example code provided.

import bar_chart_race as bcr
df = bcr.load_dataset('covid19_tutorial')
bcr.bar_chart_race(
        df=df, 
        filename='../docs/images/covid19_horiz.gif', 
        orientation='h', 
        sort='desc', 
        n_bars=8, 
        fixed_order=False, 
        fixed_max=True, 
        steps_per_period=20, 
        period_length=500, 
        end_period_pause=0,
        interpolate_period=False, 
        period_label={'x': .98, 'y': .3, 'ha': 'right', 'va': 'center'}, 
        period_template='%B %d, %Y', 
        period_summary_func=lambda v, r: {'x': .98, 'y': .2, 
                                          's': f'Total deaths: {v.sum():,.0f}', 
                                          'ha': 'right', 'size': 11}, 
        perpendicular_bar_func='median', 
        colors='dark12', 
        title='COVID-19 Deaths by Country', 
        bar_size=.95, 
        bar_textposition='inside',
        bar_texttemplate='{x:,.0f}', 
        bar_label_font=7, 
        tick_label_font=7, 
        tick_template='{x:,.0f}',
        shared_fontdict=None, 
        scale='linear', 
        fig=None, 
        writer=None, 
        bar_kwargs={'alpha': .7},
        fig_kwargs={'figsize': (6, 3.5), 'dpi': 144},
        filter_column_colors=False) 

After installing everything (including ffmpeg) I always get these 2 errors:

UserWarning: FixedFormatter should only be used together with FixedLocator ax.set_yticklabels(self.df_values.columns)

UserWarning: FixedFormatter should only be used together with FixedLocator ax.set_xticklabels([max_val] * len(ax.get_xticks()))

Is there any way around this? I find it a bit weird that the example code is not working properly.

Thanks in advance!
