My program is suppose to change 12 zeros on random positions to 1 in python 6×6 matrix. This is my code. So my matrix is going to look like this at the beggining So I randomly chose an array and the element in chosen array. The problem is that different number of zeros is changed every time. Not 12 like

Output is an empty file
My code does not throw an error, it simply creates the files, but of which are empty. I tried it from the command line, and it works using the wildcard training_set_pssm/*.pssm path, but I must do it from the IDE because it is not printing the correct output anyway. The input file is a set of checkpoint files that look
resolve matrix lists with lambda and map
we have 3 lists in below so , how we can sum all of similar index in lists together? i mean is 2 and 5 and 8 be sum together & 3 and 6 and 9 also be sum together & 4 and 7 and 10 as well ? but just use lambda and map… actually i have no idea
Iterate through an adjacency matrix with a list
So I have a n x n adjacency matrix, N x N NumPy array, where the i-th row and the j-th column is the distance between the i-th and j-th cities. I also have list, in a specific order in which I have to visit the cities and and add the distances together. The list items are pointing to row/column
How to change pixel value based on a condition
The image is 1920 by 1080. How can I change the value of a pixel when a channel value is higher than the other? Here is what I did. Is there a more efficient way than iterating on each pixel? Answer Don’t use any loop for this, use ndarray capability and logical indexing. What you want to achieve is something
How can I make this matrix in python without using numpy?
I have to make a matrix thats N by N and the example im given looks like this: So what I get from the example is that its gonna take the number N is (4 in this example since its 4 by 4) and print the number on the top row first column then fill it with zeros and then
Check if any element of a list is in a matrix?
I have a small list: and I have a matrix too. for example: And I need to determine if any of the elements of l ist2 of this array are not in the matrix2. I try to use np.isin() : But this code only shows if there is the elements in the matrix or not completely. But I need this
Numpy matrix creation timing oddity
My application requires a starting matrix where each column is staggered-by-1 from the previous. It will contain millions of complex numbers representing a signal, but a small example is: I tried two creation methods, one fast, one slow. I don’t understand why the fast matrix creation method causes subsequent calculations to run slowly, while the slow matrix creation results in
