抱歉,是我疏忽了。正确的代码应该是`pd.read_excel`而不是`pd.read`。请尝试以下代码:
```python
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.tree import DecisionTreeClassifier
from sklearn.metrics import accuracy_score
# 加载数据
data = pd.read_excel('D:\DESKTOP\default of credit card.xls')
# 分离自变量和因变量
X = data.iloc[:, :-1] # 自变量
y = data.iloc[:, -1] # 因变量
# 将数据集分为训练集和测试集
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# 建立决策树分类器
clf = DecisionTreeClassifier(random_state=42)
# 使用训练数据拟合分类器
clf.fit(X_train, y_train)
# 使用测试数据进行预测
y_pred = clf.predict(X_test)
# 计算模型的准确度
accuracy = accuracy_score(y_test, y_pred)
print('分类器的准确度为:', accuracy)
```
这段代码中,我们使用了`pd.read_excel`函数来读取Excel文件。如果您的Excel文件名或路径中包含特殊字符,请使用raw字符串,即在字符串前加上'r',例如:`r'D:\DESKTOP\default of credit card.xls'`。
