As stated in the title, I want to obtain the n-th (e.g. 4-th) order antiderivative of a 3D field (e.g. array with shape (1024,1024,1024) ) with period L on each
Can someone explain exactly what the axis parameter in NumPy does? I am terribly confused. I'm trying to use the function myArray.sum(axis=num) At first I t
I'm trying to make an AI attempting to predict numbers from prime number sequence, but my model outputs "[[nan]]". My csv file is formatted like this: number of

I am trying to build an example to understand image segmentation, you are given an image of shape (1,2,2,3) it's a 2x2 image where each pixel has 3 numbers indi
I am attempting to compute the distance matrix for an ndarray that I have converted from pandas. I tried to convert the pandas df currently in this format: move
Beginner here. I recently converted my images to grayscale using opencv. Then I used those images for training. When I was training, there was an error. "Invali
Given a 3d array X with dimensions (K,n,m) that can be considered as a stack of K (n,m) matrices and a 1d vector b (dim n), the goal is to obtain the resulting
Hi is there a way to efficiently stack the same row in each layer of a 3D numpy array? I have an array like this: a = np.array([[["a111","a112","a113"],
