如何在google Colab中显示图像？

Question

当我使用

cv2.imshow(img)

colab抛出一个DisabledFunctionError（https://github.com/jupyter/notebook/issues/3935）。 使用cv2_imshow（img）我得到另一个错误，AttributeError: 'NoneType' object has no attribute 'clip')

我怎样才能解决这个问题

Answer 1

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

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：

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

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

Answer 2

试试这个：

from google.colab.patches import cv2_imshow
cv2_imshow(img)
