cv2.imshow()使内核崩溃 [英] cv2.imshow() crashes Kernel

问题描述

我正在通过Jupyter Notebook运行OpenCV，每当我尝试运行cv2.imshow()时，内核崩溃，没有错误消息或有用的提示-只是一个简单的

I am running OpenCV through Jupyter Notebooks and whenever I try to run cv2.imshow() the kernel crashes, no error message or helpful hint - just a plain

The Kernel appears to have died. It will restart automatically.

这是我正在运行的代码...

Here is the code I am running...

import cv2 
input = cv2.imread('images/input.jpg')
cv2.imshow('Hello World', input)
cv2.waitKey(0)
cv2.destroyAllWindows()

当我运行以下代码时，代码工作(尽管有所不同)...

The code works (albeit differently) when I run the below...

%matplotlib inline
from matplotlib import pyplot as plt
import cv2
image = cv2.imread('images/input.jpg')
plt.imshow(image)
plt.show()

仅供参考，我正在使用AWS上完全不变的BitFusion副本.

FYI I am using a completely unaltered copy of BitFusion on AWS.

有什么想法会出问题吗?

Any idea what could be going wrong?

推荐答案

我现在无法解释您的代码的行为，但是您可以使用以下代码来实现上述行为.

I can't explain the behavior of your code right now but you can use the below code to achieve the above behavior.

%matplotlib inline
from matplotlib import pyplot as plt
import cv2
image = cv2.imread('images/input.jpg')
plt.imshow(image)
plt.show()
