如何在NumPy中更改数组数组中的轴的值？

Question

I have a 4-level 4-dimensional array contours (result of cv2.findContours ) at the end of which I have pairs of coordinates. It looks like this:

print(contours[0][0])
→ [[ 676 4145]]
print(contours[0][0][0])
→ [ 676 4145]
print(contours[0][0][0][1])
→ 4145

I want to edit the axis element 1 of each of the last-level arrays so that the value is bigger by 10. I am aware of the documentation , but I don't know how to apply it so deep without flattening. How to do that?

Answer 1

这些中的任何一个都可以工作：

• contours[:,:,:,1] += 10
• contours[...,1] += 10
• contours += [0, 10]
