image_path = 'image_06621.jpg' img = process_image(image_path) imshow(img)

上面的代碼是執行對圖像的展示的相關代碼，但是出現了下面的報錯：

NameError: name ‘imshow’ is not defined.

原因是沒有導入matplotlib，在第一行加入：

import matplotlib.pyplot as plt

import matplotlib.pyplot as plt image_path = 'image_06621.jpg' img = process_image(image_path) imshow(img)

?然后又出現了下面的報錯，沒有畫出相應的圖像：

?原因是圖像的矩陣錯誤，錯誤提示了相應的解決辦法，圖像的第三個參數是顏色通道的個數，將其進行轉置后就能畫出相應的圖像

import matplotlib.pyplot as plt image_path = 'image_06621.jpg' img = process_image(image_path) imshow(img.T)
