错误使用numpy.logspace（）：如何生成数字均匀隔开对数

Question

我试图使用numpy.logspace()生成从1e-10到1e-14 50个值。

http://docs.scipy.org/doc/numpy/reference/generated/numpy.logspace.html

import numpy as np 
x = np.logspace(1e-10, 1e-14, num=50) 
print x 

我得到的输出是不正确的：

[ 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 
    1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 
    1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1.] 

我有什么其他选择？

>>> import numpy as np 
>>> np.logspace(-10, -14, 50)
