I am trying to draw randomly over the image. Image can be either .jpeg file or simple black background. Once the drawing is complete I need to save the drawing as a numpy array.
I have found a few solutions that might work but non of them work for me for some reason.
For example, one idea is to use tkinter
However, when I run the codes above it just seems to "run" in the infinite loop in the first three lines. I am also note sure how to convert this drawing into numpy.
I have also tried this:
I also have seen some turtle solution but have not tried.
Any ideas/suggestions would be appreciated.
Thank you!

from tkinter import * app = Tk() app.mainloop canvas = Canvas(app, bg='black') canvas.pack(anchor='nw', fill='both', expand=1) def get_x_and_y(event): global lasx, lasy lasx, lasy = event.x, event.y def draw_smth(event): global lasx, lasy canvas.create_line((lasx, lasy, event.x, event.y), fill='red', width=2) lasx, lasy = event.x, event.y ()

I have also tried this:
import cv2 import numpy as np im = cv2.imread("einstein.jpg") cv2.namedWindow("Jenya Polyakova OpenCV") cv2.setMouseCallback('Jenya Polyakova OpenCV',geology_draw) while(1): cv2.imshow('Jenya Polyakova OpenCV',im) k=cv2.waitKey(1)&0xFF if k==27: break cv2.destroyAllWindows()Again, it just seems to go into infinite loop. I am using jypiter notebook to compile.
