Na execução da célula:
img = io.imread('1200x630wa.png')
img = color.rgb2gray(img)
img = transform.resize(img, (img.shape[0]//10, img.shape[1]//10) )
saida = convolve(img, kernel_v, 'valid')
plt.imshow(img, cmap='gray')
plt.title('Imagem')
plt.figure(figsize=(8, 5))
plt.imshow(np.abs(saida), cmap='gray')
plt.colorbar()
plt.title('Mapa de ativação')
tive o seguinte retorno no collab:
