我正在使用 statsmodels.api 应用向后消除，代码给出了此错误 `TypeError: ufunc 'isfinite' 不支持输入类型，并且根据转换规则 ''safe'，无法将输入安全地强制为任何受支持的类型'

我不知道如何解决它

这是代码

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
from sklearn.linear_model import LinearRegression
from sklearn.model_selection import  train_test_split
from sklearn.preprocessing import  LabelEncoder, OneHotEncoder
from sklearn.compose import  ColumnTransformer
import statsmodels.api as smf

data = pd.read_csv('F:/Py Projects/ML_Dataset/50_Startups.csv')
dataSlice = data.head(10)

#get data column
readX = data.iloc[:,:4].values
readY = data.iloc[:,4].values

#encoding c3
transformer = ColumnTransformer(
    transformers=[("OneHot",OneHotEncoder(),[3])],
    remainder='passthrough' )
readX = transformer.fit_transform(readX.tolist())
readX = readX[:,1:]

trainX, testX, trainY, testY = train_test_split(readX,readY,test_size=0.2,random_state=0)

使用 python 如何使用 selenium 获取背景图像？哪个有内联 CSS？我想从背景图片中获取图片网址： url()

<div id="pic" class="pic" data-type="image" style=" background-image: url(http://test.com/images/image.png;); height: 306px; background-size: cover;"></div>
