Using -1 as a shape dimension when flattening the array Flatten only some Dimensions of a NumPy array using numpy.vstack() #How to flatten only some Dimensions of a NumPy array Use thenumpy.reshape()method to flatten only some dimensions of a NumPy array. The method will flatten the array...
NumPy This tutorial will introduce the methods to add a new dimension to a NumPy array in Python. Add Dimension to NumPy Array With thenumpy.expand_dims()Function Thenumpy.expand_dims()functionadds a new dimension to a NumPy array. It takes the array to be expanded and the new axis as ...
A step-by-step guide on how to check if a NumPy array is multidimensional or one-dimensional in multiple ways.
How to make numpy.argmax() return all occurrences of the maximum? Averaging over every n elements of a NumPy array How to find the groups of consecutive elements in a NumPy array? Count all values in a matrix less than a value
Suppose that we are given with a numpy array and we need to find the indices of all elements in an array that are greater than a specific value a and less than a specific value b.The numpy.where()The numpy.where() returns a tuple of length equal to the dimension of the numpy ...
If X is a multidimensional array, there will be more variables to represent the sizes of each dimension. The size() function supports two arguments. The first argument is the name of our matrix (with some data), of which we want to get the number of columns. The second argument can be...

We can use the NumPy max function to compute the maximum value: Although this example shows you how thenp.max()function operates on a 1-dimensional NumPy array, it operates in a similar way on 2-dimensional arrays and multi-dimensional arrays. Again, I’ll show you full examples of these...
First of all, let’s start with what the variance function does. The Numpy variance function calculates the variance of values in a Numpy array. At a high level, that’s really all it does? To help you understand this though, let’s do a quick review of what variance is, as well as...
