@jklymak Thanks! And yes, it's the pandas 0.25.0 that causes the failure, 0.24.2 was fine.
Can we change the test_bar_pandas(pd) to following to avoid this failure?
def test_bar_pandas(pd):
# Smoke test for pandas
pd.plotting.register_matplotlib_converters()
fig, ax = plt.subplots()
df = pd.DataFrame(
{'year': [2018, 2018, 2018],
'month': [1, 1, 1],
'day': [1, 2, 3],
'value': [1, 2, 3]})
df['date'] = pd.to_datetime(df[['year', 'month', 'day']])
monthly = df[['date', 'value']].groupby(['date']).sum()
dates = monthly.index
forecast = monthly['value']
baseline = monthly['value']
ax.bar(dates, forecast, width=10, align='center')
ax.plot(dates, baseline, color='orange', lw=4)
pd.plotting.deregister_matplotlib_converters()i.e. register at beginning and deregister at the end.
