在所需轴上拆分 3D numpy 数组
[英]Spliting a 3D numpy array on desired axis
问题描述
I have a NumPy array of shape (4809, 200, 31) and i want to extract following array out of it : shape (4809, 200, 1).
我有一个形状为 (4809, 200, 31) 的 NumPy 数组，我想从中提取以下数组：形状 (4809, 200, 1)。 so I want to extract one column from axis=2 from the source array which will have three-axis (0,1,2).所以我想从具有三轴（0,1,2）的源数组中从axis = 2中提取一列。

Its as simple as doing它就像做一样简单
A[:,:,0:1]. A[:,:,0:1]。 Thanks @Mark for the answer.感谢@Mark 的回答。
