Question

我是机器学习python的初学者，我设置了该代码，它工作得很好，但是当我运行这段代码plt.plot(X_train,Y_train, color = 'red')时，它给了我错误：

TypeError: 'tuple' object is not callable

代码：

#splitting data
from sklearn.cross_validation import train_test_split
X_train, X_test, Y_train, Y_test= train_test_split(X, Y, test_size=0.33, 
random_state=0)

#fitting simple linear regression to the training set
from sklearn.linear_model import LinearRegression
regressor=LinearRegression()
regressor.fit(X_train,Y_train)
#predicting the test set results
Y_pred=regressor.predict(X_test)

#plotting the training set
plt.plot(X_train,Y_train, color = 'red')
plt.plot(X_train,regressor.predict(X_train), color = 'blue')
plt.title('exp vs salary(training set)')
plt.xlabel('exp')
plt.ylabel('salary')
plt.show()

Answer 1

除非看到完整的追溯，否则我们无法说出任何具体的内容。但是，看来您的matplotlib.pyplot函数有问题。尝试再次导入它或在命令行中对其进行更新。

Answer 2

try：plt.scatter（X_train，Y_train，color ='red'）
