You can use len() with multi-dimensional NumPy arrays, but it will return the size of the first dimension. If you want to get the size of other dimensions or the total number of elements, you should use the appropriate array attributes like shape or size. Is there a NumPy function to ...

Python NumPy nanmean() function is used to compute the arithmetic mean or average of the array along a specified axis while ignoring NaN (Not a Number)
In this OpenCV Tutorial, we will learn how to get image size in OpenCV Python using NumPy Array shape property, with an example.
