Matplotlib - Seaborn-whitegrid 不是有效的包样式

Question

我使用 ADTK 进行异常检测，使用 matplotlib 进行可视化，但在尝试运行程序时遇到错误。这是我的代码，我使用 python3 运行

import pandas as pd
import matplotlib.pyplot as plt
import matplotlib.dates as mdates

 
from adtk.data import validate_series
from adtk.visualization import plot
from adtk.detector import PersistAD

data = pd.read_csv('SQL_bytes_sent_ferdig.csv', index_col="time", parse_dates=True)
# Convert the index to a DatetimeIndex explicitly if it's not already
data.index = pd.to_datetime(data.index, utc=True)

# Add 1 hour to the index
data.index = data.index + pd.Timedelta(hours=1)
data_valid = validate_series(data)


persist_ad = PersistAD(c=3.0, side='positive')
anomalies = persist_ad.fit_detect(data_valid)

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

运行此命令会出现以下错误：

The above exception was the direct cause of the following exception:

  File "/home/ubuntu/ad/sql_ad.py", line 22, in <module>
    plot(data_valid, anomaly=anomalies, ts_linewidth=1, ts_markersize=3, anomaly_markersize=3, anomaly_color='red', anomaly_tag="marker");

    raise OSError(
OSError: 'seaborn-whitegrid' is not a valid package style, path of style file, URL of style file, or library style name (library styles are listed in `style.available`)

我查看了其他具有类似问题的帖子，并尝试指定在我的代码中使用哪种样式，其中我有以下样式：

import matplotlib.pyplot as plt
# plt.style.use(['science', 'notebook'])
print(plt.style.available)

给予：

['Solarize_Light2', '_classic_test_patch', '_mpl-gallery', '_mpl-gallery-nogrid', 'bmh', 'classic', 'dark_background', 'fast', 'fivethirtyeight', 'ggplot', 'grayscale', 'seaborn-v0_8', 'seaborn-v0_8-bright', 'seaborn-v0_8-colorblind', 'seaborn-v0_8-dark', 'seaborn-v0_8-dark-palette', 'seaborn-v0_8-darkgrid', 'seaborn-v0_8-deep', 'seaborn-v0_8-muted', 'seaborn-v0_8-notebook', 'seaborn-v0_8-paper', 'seaborn-v0_8-pastel', 'seaborn-v0_8-poster', 'seaborn-v0_8-talk', 'seaborn-v0_8-ticks', 'seaborn-v0_8-white', 'seaborn-v0_8-whitegrid', 'tableau-colorblind10']

但是它们都没有改变错误。在 Jupytor Notebook 中运行它可以工作，我什至不必指定要使用哪个图。我尝试使用 pip 安装seaborn，但仍然不起作用。

@Elias Rudsbråten，我也遇到了这个问题，我通过将

seaborn-whitegrid

替换为

seaborn-v0_8-white grid

来修复它。我很好奇你最终能否找到

seaborn-white grid

的解决方案。
