前言

在vscode中使用opencv-python報錯：

一、錯誤原因

1.首先

numpy matplotlib opencv_python這些我已經在本機配置安裝

pip install numpy matplotlib opencv_python

二、解決方法

1.在vscode：Python:Select Interpreter

當python環境不止一個時，vscode可以選擇指定的python解釋器，具體為：

vscode設定中打開Command Palette，ctrl+shift+p

輸入Python:Select Interpreter

根據自己機器的python.exe 選擇

這樣vscode下能夠識别cv2

2.依然報錯：cv2.error: OpenCV(4.7.0) D:\a\opencv-python\opencv-python\opencv\modules\highgui\src\window.cpp:1272: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function ‘cvShowImage’

解決方法：在vscode終端輸入 :pip install ffmpeg

3.再次報錯：WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ConnectTimeoutError(<pip._vendor.urllib3.connection.HTTPSConnection object at 0x0000028558508F40>, ‘Connection to files.pythonhosted.org timed out. (connect timeout=15)’)’: /packages/f0/cc/3b7408b8ecf7c1d20ad480c3eaed7619857bf1054b690226e906fdf14258/ffmpeg-1.4.tar.gz

解決：解除安裝opencv-python

4.在vscode終端重裝opencv-python

pip install opencv-python

5.代碼

import cv2


img = cv2.imread('E:/openCVExercise/pythonOpenCV/1.jpg')
cv2.imshow('img', img)
cv2.waitKey(0)
           

6.運作
