NumPy Tutorial: NumPy is the fundamental package for scientific computing in Python. It is a Python library that provides a multidimensional array object, various derived objects (such as masked arrays and matrices), and an assortment of routines for fa
vsplit沿垂直方向分裂 轴,和 array_split允许 一个指定沿哪个轴拆分。 副本和视图 在操作和操作数组时,它们的数据有时会被复制 进入一个新的阵列,有时不是。 这通常是混淆的根源 给菜鸟的。 有以下三种情况: 完全没有复制 简单赋值不会复制对象或其数据。 a = np.array([[ 0, 1, 2, 3], [ 4,...

Splitting one array into several smaller ones(将一个数组拆分为几个较小的数组) Usinghsplit, you can split an array along its horizontal axis, either by specifying the number of equally shaped arrays to return, or by specifying the columns after which the division should occur: ...
importnumpyasnp# Create a numpy arrayarray=np.array([1,2,3,4,5,6])# Split the array into three equally sized subarraysresult=np.split(array,3)print(result)# Output:# [array([1, 2]), array([3, 4]), array([5, 6])]
翻译自Quickstart tutorial¶ NumPy的主要的对象是同类的多维数组(homogeneous multidimensional array)。 NumPy的维度(dimensions)被称为轴(axes)。 轴的数字代表rank。 例如,在三维空间中一个坐标(coordinates)为[1,2,1]的点是一维...
