NumPy Splitting Arrays Python Tutorial In 2020 Tutorial Learn To
In this post you will learn how to find the n largest values of a NumPy array in Python Now what should be the first step to get the number We want our data or array to be sorted Our approach for this should be the sorting and negative indexing method The code should be pretty straightforward Let us now see this with an example Find n largest values of a NumPy array in Python CodeSpeedy. There are multiple ways to get indices of N maximum values in a NumPy array Lets discuss all the methods one by one with proper approach and a working code examples Method 1 Using argpartition function The numpy module has argpartition function It takes an array and an integer N as input arguments and returns an array of indices 6 The situation is as follows I have a 2D numpy array Its shape is 1002 1004 Each element contains a value between 0 and Inf What I now want to do is determine the first 1000 maximum values and store the corresponding indices in to a list named x and a list named y
