安装 mediapipe 库后 cv2 不起作用

Question

我想使用 python 制作 handtracker 程序，但教程告诉我安装 mediapipe 库，然后我安装了它。在此之前，使用 cv2 来传输我的相机是可以的，但是在安装 mediapipe 后，cv2 在这里不起作用，消息如下：

>>>import cv2
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import cv2
  File "C:\Users\windows\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2\__init__.py", line 181, in <module>
    bootstrap()
  File "C:\Users\windows\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2\__init__.py", line 175, in bootstrap
    if __load_extra_py_code_for_module("cv2", submodule, DEBUG):
  File "C:\Users\windows\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2\__init__.py", line 28, in __load_extra_py_code_for_module
    py_module = importlib.import_module(module_name)
  File "C:\Users\windows\AppData\Local\Programs\Python\Python39\lib\importlib\__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "C:\Users\windows\AppData\Local\Programs\Python\Python39\lib\site-packages\cv2\gapi\__init__.py", line 290, in <module>
    cv.gapi.wip.GStreamerPipeline = cv.gapi_wip_gst_GStreamerPipeline
AttributeError: partially initialized module 'cv2' has no attribute 'gapi_wip_gst_GStreamerPipeline' (most likely due to a circular import) ```

我尝试再次安装 opencv 但总是收到此消息：

Requirement already satisfied: numpy>=1.19.3 in c:\users\windows\appdata\local\programs\python\python39\lib\site-packages (from opencv-python) (1.21.1)

但问题仍然存在。我如何解决它？

编辑：这是我的点子列表

C:\Users\windows>pip list

我也有和上面一样的情况，你可以试试：

pip install "opencv-python-headless<4.3"

该命令成功解决了这种情况
