I have the following DataFrame, output_excel, containing inventory data and sales data for different products. See the DataFrame below: Please note ...
For example, I have a numpy array like: a = np.array([0.5, 0.1, 0.5)]. When I use np.argsort(a)[::-1] to sort my array in descending order, it return ...
Given a numpy ndarray like the following I want to find the indices of the top k (e.g. k=3) elements of each row, excluding 0, if possible. If ther ...
What is the problem? Where am I doing wrong? I am new to Python and I could not find the problem. Thanks a lot in advance for your help. The code is ...
Above is numpy.ndarray of the shape (13,13) with errors obtaining in a certain classification task using two of the 13 features. The task here is t ...
I have the following code that's supposed to order a NumPy "matrix" based on the order of the elements of the first "row". I am dealing with SymPy var ...
I'm annoyed with myself for not figuring this out on my own; it is most likely trivial. But anyway, suppose I have an unsorted array, and an argsort f ...
I have a Python iterative quicksort implementation. I'd like to do an argsort instead of a sort though, so that the resulting array has the ranking of ...
I use numpy.argsort all the time for 1D data, but it seems to behaving differently in 2D. For example, let's say I want to argsort this array along a ...
I have a very large array but here I will show a simplified case: I want to argsort() the array but have a way to distinguish 0s. I tried to replac ...
I want to benchmark np.argsort by comparing different sorting algorithms, that are ‘quicksort’, ‘mergesort’, ‘heapsort’, ‘stable’ available in the np. ...
I have a 1D numpy array I need to calculate another array of the same size, where each element is the ID (or called index) in the sorted array. Her ...
I have two lists: a list of 2D-arrays and the time it was generated, which is an integer. They are of length N and both "equally disordered". So by us ...
I have an array of dimension (43, 25520). I want to sort them for every of those 43 columns and then store the sorted indices for every row in a new ...
I would like to apply a sort operation, row per row, only keeping values above a given threshold. For this, I see I can use a masked array to apply t ...
I'm trying to remove the argsort function, so that it will just print in order of prediction classes (I.e. if I am trying to predict "a-d" classificat ...
I have, I want to calculate at K map, which I wrote an algo as below, It basically gives calculation formula like below: (1 + 0 + 2 / 3) / 3 + ...
