This can be Interactive image stack viewing in jupyter notebooks based on ipycanvas and ipywidgets. pyplot as plt import cv2 import numpy as np from IPython. The notebook we'll use includes a number of cells that build an image classifier using PyTorch. imshow(img) is crashing the server. To read the images cv2. imshow(). I am also facing a same issue in google colab. We can use cv2_imshow() instead of (cv2. imread(). patches import cv2_imshow You signed in with another tab or window. fromarray() of PIL module. 1, please first multiply img by 255 # assume image is ndarray of shape [height, width, channels] where channels can be 1, 3 or 4 def imshow(img): Item Value; CPUs: Apple M1 (8 x 24) GPU Status: 2d_canvas: enabled canvas_oop_rasterization: disabled_off direct_rendering_display_compositor: disabled_off_ok Image processing is a method to perform some operations on an image, in order to get an enhanced image or to extract some useful information from it. waitForKey() and cv2.
