Я пытаюсь визуализировать данные Worldometer Covid19, но когда я делаю seaborn lmplot, я получаю сообщение об ошибке:
IndexError: Invalid index to scalar variable.
Графики также отображаются с ошибкой, но я предпочитаю показывать их без сообщения об ошибке.
вот фрагмент кода (lmplot находится в самом конце):
# Read Dataset
df = pd.read_csv('../input/corona-virus-report/worldometer_data.csv')
# Fill missing values with zeros
df= df.fillna(0)
# Deaths per 1M population for each continent
plt.figure(figsize=(10,6))
sns.barplot(x=df['Continent'],y=df['Deaths/1M pop'])
# Distribution of Deaths per 1M population
plt.figure(figsize=(10,6))
sns.kdeplot(data=df['Deaths/1M pop'],shade=True)
# Distribution of Cases per 1M population
plt.figure(figsize=(10,6))
sns.kdeplot(data=df['Tot Cases/1M pop'],shade=True)
# Joint Distribution of Deaths and Cases per 1 M Population.
plt.figure(figsize=(10,6))
sns.jointplot(x=df['Tot Cases/1M pop'], y=df['Deaths/1M pop'], kind="kde")
# We slice the dataset into a dataframe of the columns we need to plot
selected_df2 = df.loc[:,['Tot Cases/1M pop','Tests/1M pop','Continent']]
# first plot is to show the relation between tests and cases per 1M poplulation.
plt.figure(figsize=(10,6))
sns.regplot(x=selected_df2['Tests/1M pop'],y=selected_df2['Tot Cases/1M pop'])
# Second plot is uses the Continent as hue to detect if there is a genetic effect.
plt.figure(figsize=(10,6))
sns.lmplot(x="Tests/1M pop",y="Tot Cases/1M pop", hue="Continent", data=df)
и вот ошибка:
<!-- language: none -->

пожалуйста, помогите исправить эту ошибку ... Спасибо :)
