如何在Google Colab中显示图片? [英] How do i show an image in google Colab?

问题描述

当我使用cv2.imshow(img)时，colab给出DisabledFunctionError( https://github.com/jupyter/notebook/issues/3935 )，所以我使用了cv2_imshow(img)，该错误给出了图片所示的错误(AttributeError:"NoneType"对象没有属性"clip").

When I use cv2.imshow(img), colab gives DisabledFunctionError (https://github.com/jupyter/notebook/issues/3935) so I used cv2_imshow(img) which is giving this error as shown in picture(AttributeError: 'NoneType' object has no attribute 'clip').

推荐答案

在Google Colab中使用cv2.imshow(img)返回以下输出:

Using cv2.imshow(img) in Google Colab returns this output:

DisabledFunctionError: cv2.imshow() is disabled in Colab, because it causes Jupyter sessions
to crash; see https://github.com/jupyter/notebook/issues/3935.
As a substitution, consider using
  from google.colab.patches import cv2_imshow

因此，您可以简单地使用:

Accordingly, you can simply use:

from google.colab.patches import cv2_imshow
import matplotlib.pyplot as plt

img = "yourImage.png"
img = cv2.imread(img) # reads image
plt.imshow(img)
