python - pyplot.scatter(c ='red')。无效的语法？

Question

我是机器学习的初学者，我在 pyplot 的分散方法中遇到了颜色错误，“s=None”参数也出现了同样的错误

pyplot.scatter = (X_train, y_train, c = 'red')
pyplot.plot = (X_train, regressor.predict(X_train), c = 'blue')

我收到此错误

plt.scatter = (X_train, y_train, c = 'red')
                                   ^
SyntaxError: invalid syntax

如何消除此错误以及何时将“color = 'red'”替换为“c = 'red'”？

Answer 1

您必须删除=:

pyplot.scatter(X_train, y_train, c = 'red')
pyplot.plot(X_train, regressor.predict(X_train), c = 'blue')

PS。 按照惯例，通常以这种方式导入 matplotlib 库:

import matplotlib.pyplot as plt
plt.scatter(X_train, y_train, c = 'red')
