该库在运行 Python 虚拟环境时在 function 错误中编译时没有 QT 支持

Question

我试图运行这个已安装的库 - https://github.com/alkasm/magicwand但是当我尝试在命令行“python -m magicwand C:\Users\home\Pictures\img.png”中运行命令时，它返回了这个错误 -

Traceback (most recent call last):
  File "C:\Users\home\AppData\Local\Programs\Python\Python38-32\lib\runpy.py", line 194, in _run_module_as_main
    return _run_code(code, main_globals, None,

cv2.error: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\highgui\src\window.cpp:567: error: (-213:The function/feature is not implemented) The library is compiled without QT support in function 'cv::displayStatusBar'

我检查了问题的解决方案，但找不到。 我也已经通过 pip 安装了 opencv-python。

任何帮助将不胜感激，谢谢！

从conda安装opencv为我解决了这个问题：

conda install -c conda-forge opencv
