当给定明确的区间时,histogram 将接受 NaN 值(release/1.15.0-notes.html#histogram-will-accept-nan-values-when-explicit-bins-are-given) histogram 在给定明确的 bin 边界的情况下适用于日期时间类型 histogram“auto” 估计器更好地处理有限的方差 histogram 和histogramdd 返回的边界现在与数据浮点类型匹配 ...
我们将index词汇复数形式使用indices,而不是indexes,这遵循了numpy.indices的先例。 为保持一致性,我们也将matrix复数形式使用matrices。 未能被 NumPy 或 Google 规则充分解决的语法问题,由最新版芝加哥手册中"语法和用法"一节决定。 我们欢迎大家报告应该添加到 NumPy 风格规则中的案例。 ### 文档字符串 当将Sphinx...

In simpler words, if you have an array of say 100 elements, and you want to pick only a section of the values, then we can perform slicing and get the required set of values from the complete ndarray. In the examples below, you will see code examples for slicing....

to get a selected set of values from a NumPy array. Note that the index in ndarray starts from zero hence, there is a difference between the value and where the value is located in an array. In this article, I will explain how to get the values from an array by using its indexes....
Note that here we see that the value of the array created by empty is 0, which is not necessarily true. Empty will randomly select spaces from the memory to return, and there is no guarantee that there are no values in these spaces. So after we use empty to create the array, before...
