删除N-D numpy数组的第一个元素

I have a numpy 5D array and want to delete the first element and push a new element to the end of the index. Here goes the definition;

我有一个numpy 5D数组,想要删除第一个元素并将一个新元素推送到索引的末尾。这是定义;

images = np.zeros([1,30,image_height,image_width,image_channel])

This is the one to be deleted: images[0,0,:,:,:]

这是要删除的:图像[0,0,:,:,]

And this is the one to be updated: images[0,29,:,:,:]

这是要更新的:图像[0,29,:,:,]

How to delete and add an element from N-D sized array?

OK, I found it out.

好的,我发现了。

images[0, 0:28, :, :, :] = images[0, 1:29, :, :, :]

images[0, 30, :, :, :] = new_data

To avoid hardcoding indices it can be written as:

为避免硬编码索引,可将其写为:

images[0,0:-1,...] = images[0,1:,...]
images[0,-1,...] = new_data
