在numpy的范围内采样随机浮动 [英] sampling random floats on a range in numpy

问题描述

如何在 numpy 中以区间 [a, b] 采样随机浮点数?不只是整数，而是任何实数.例如，

How can I sample random floats on an interval [a, b] in numpy? Not just integers, but any real numbers. For example,

random_float(5, 10)

将返回 [5, 10] 之间的随机数.谢谢.

would return random numbers between [5, 10]. thanks.

推荐答案

均匀分布 可能会满足您的要求.

The uniform distribution would probably do what you are asking.

np.random.uniform(5,10) # A single value
np.random.uniform(5,10,[2,3]) # A 2x3 array
