datatype强制性改变，提示TypeError: only length-1 arrays can be converted to Python scalars
参考自stackoverflow上的答案
1 import numpy as np 2 import matplotlib.pyplot as plt 3 4 def f(x): 5 return np.int(x) 6 f2 = np.vectorize(f)#让函数矩阵化，解决只能一对一强制性变换这一要求 7 x = np.arange(1, 15.1, 0.1) 8 plt.plot(x, f2(x)) 9 plt.show()
