shape: 获取数组的形状假设是一个二维数组shape[0]: 获取数组的行数shape[1]: 获取数组的列数例：import numpy as npx = np.array([[1, 2, 3, 4], [4, 3, 2, 1]])x.shape>>> (2, 4)x.shape[0]>>> 2x.shape[1]>>> 4...

numpy.linspace | np.linspace 函数用法np.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None, axis=0)在间隔start和stop之间返回num个均匀间隔的数据。Parameters:start: array_like序列的起始值stop: array_like序列的结束值
