Python中的numpy函数的使⽤ones，zeros，eye 在看别⼈写的代码时，看到的不知道的函数，就在这⾥记下来。原⽂是这样⽤的：1 weights = ones((numfeatures,1))在python中help（）：import numpy as np help(np.ones)1 Help on function ones
Pythonnumpy.ones() function returns a new array of given shape and data type, where the element’s value is set to 1. This function is very similar to numpy zeros() function. Python numpy.ones()函数返回给定形状和数据类型的新数组,其中元素的值设置为1。此函数与numpy zeros()函数非常相似。
