[Issue] Could not find the Qt platform plugin "cocoa" in ""

純粹記錄執行Opencv的程式碼時所遇到的問題，今天在MacOS的環境測試相關程式碼時，terminal拋出下面這條錯誤訊息:

qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

[1]    2682 abort      python

trace後發現問題出在cv2.imread的function。

網路上的建議解法有：

1. reinstall qt

    brew reinstall qt
   

   重新安裝後仍然出現錯誤。

2. 安裝 opencv-python-headless

    pip install opencv-python-headless
   

   安裝後成功解決問題。
