我想几天使用OneHotEncoder。列名是day，包括星期日，星期六，星期四，星期五
ValueError：无法将字符串转换为浮点数：“ Thur”
import pandas as pd
veriler = pd.read_csv("tips.csv")
days=veriler.iloc[:,4:5].values
from sklearn.preprocessing import OneHotEncoder
ohe=OneHotEncoder(categorical_features="all")
days=ohe.fit_transform(days).toarray()
ValueError: could not convert string to float: 'Thur'
