除了几乎同义反复的 定义之外,没有类数组的正式定义——类数组是任何 np.array 可以转换为 ndarray 的Python 对象。要超越这一点,您需要研究 源代码。 NPY_NO_EXPORT PyObject * PyArray_FromAny(PyObject *op, PyArray_Descr *newtype, int min_depth, int max_depth
1. 使用Python列表创建数组: ```python import numpy as np data_list = [1, 2, 3, 4, 5] arr = np.array_like(data_list) print(arr) ``` 通过上述代码可以看到,我们可以将一个Python列表转换成NumPy数组,并且通过print函数打印出数组的内容。 2. 使用元组创建数组: ```python data_tuple = (6,...

工作中阅读文档,常常会遇到array-like parameter. 虽然能够从字面理解其含义, 但自己始终觉得被蒙上一层纱. 因此, 通过查阅资料 [1]的方式了解了array-like到底是什么.↓ an array-like is any Python object that…

python学习——NumPy数值计算基础 NumPy基础知识概览:涉及nan(非数字)和inf(无穷)的概念,nan在文件读取或不适当计算时出现,inf在除0操作中出现。数组操作有深拷贝(a=b.copy())、浅拷贝(a=b[:])和引用(a=b)。创建数组方式多样,如`np.array()`、`np.arange()`等。数据类型转换如`np.float64()`、`np...
When evaluating lhs + rhs, Python will only call rhs.__radd__(lhs) if lhs.__add__(rhs) returns NotImplemented, or if type(rhs) is a subclass of type(lhs) (described here). JAX allows custom types to be converted to JAX arrays by calling their __jax_array__ method, if it exist...
