我们将导入名称缩短为np,以提高使用 NumPy 的代码的可读性。这是一个被广泛采用的惯例,可以使你的代码对每个人在上面工作时更容易阅读。我们建议始终使用import numpy as np导入。 阅读示例代码 如果你还不习惯阅读包含大量代码的教程,你可能不知道如何解释如下的代码块: ...
你可以在np.unique()中传递return_counts参数和数组一起,以获取 NumPy 数组中唯一值的频次计数。 >>> unique_values, occurrence_count = np.unique(a, return_counts=True)>>> print(occurrence_count)[3 2 2 2 1 1 1 1 1 1] 这也适用于二维数组!如果你从这个数组开始: ...
