在python中将np.ndarray转换为np.array [英] Convert np.ndarray to np.array in python

问题描述

我有一些数据作为np.ndarray加载，需要将其转换为np.array.

I have some data loaded as a np.ndarray and need to convert it to a np.array.

是否有一种简便/快速的方法，而不必以其他方式重新加载数据?

Is there an easy/quick way of doing this without having to re-load the data in a different way?

我在教程中可以找到的所有信息似乎都涉及一种数组或另一种类型，而不是如何将数据从一种更改为另一种.

All the information I can find in tutorials seems to refer to one type of array or the other, but not how to change data from one to the other.

推荐答案

它们是相同的:numpy.array是用于构造类型为numpy.ndarray的对象的函数.

They are the same: numpy.array is a function that constructs an object of type numpy.ndarray.

>>> import numpy
>>> numpy.ndarray
<type 'numpy.ndarray'>
>>> numpy.array
<built-in function array>
>>> numpy.array([])
array([], dtype=float64)
>>> isinstance(numpy.array([]), numpy.ndarray)
True
