I encountered a strange error when using adtk's plot method: ValueError: Multi-dimensional indexing (e.g. obj[:, None]) is no longer supported. Convert to a numpy array before indexing instead

My code is:

` df = pd.read_csv('cleaned_data/原始值-周均价.csv') df['date'] = pd.to_datetime(df['date']) df.set_index('date',inplace=True) df = validate_series(df)

from adtk.data import validate_series from adtk.visualization import plot from adtk.transformer import RollingAggregate from adtk.transformer import DoubleRollingAggregate from adtk.detector import ThresholdAD threshold_ad = ThresholdAD(high=10, low=5) anomalies = threshold_ad.detect(df)

plot(df, anomaly=anomalies, ts_linewidth=1, ts_markersize=3, anomaly_markersize=5, anomaly_color='red', anomaly_tag="marker"); `

I encountered an error:

` ValueError Traceback (most recent call last) Cell In[25], line 18 13 threshold_ad = ThresholdAD(high=10, low=5) 14 anomalies = threshold_ad.detect(df) ---> 18 plot(df, anomaly=anomalies, ts_linewidth=1, ts_markersize=3, anomaly_markersize=5, anomaly_color='red', anomaly_tag="marker");

My version information：

adtk==0.6.2

I have made the following solutions, but none of them can be solved:

1. I asked chatgpt, and it told me to switch to an array, but although I knew that the plot method required df, I still tried an array, and it was really an error.

I can't solve this problem. The great open source tycoon can give me some suggestions or solutions.
