我是机器学习python的初学者，我设置了该代码，并且运行良好，但是当我运行代码plt.plot(X_train,Y_train, color = 'red')的此部分时，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()
，除非我们看到完整的痕迹，否则我们不能说任何具体的内容。但是，您的matplotlib.pyplot函数似乎存在问题。尝试再次导入或在命令行中更新。
尝试：plt.scatter(x_train，y_train，color ='red''(
