我可以在 python 中抑制 OpenCV / cv2 警告吗？
Can I supress OpenCV / cv2 warnings in python?
问：
每当我尝试该命令时，我都会收到以下警告cv2.VideoCapture(video_name)
[ WARN:[email protected]] global /private/var/folders/k1/30mswbxs7r1g6zwn8y4fyt500000gp/T/abs_11nitadzeg/croot/opencv-suite_1691620374638/work/modules/videoio/src/cap_gstreamer.cpp (2386) handleMessage OpenCV | GStreamer warning: your GStreamer installation is missing a required plugin
还有 3 个，几乎完全相同。仅来自单行代码 VideoCapture（当然上面有一个导入）的整个警告是
[ WARN:[email protected]] global /private/var/folders/k1/30mswbxs7r1g6zwn8y4fyt500000gp/T/abs_11nitadzeg/croot/opencv-suite_1691620374638/work/modules/videoio/src/cap_gstreamer.cpp (2386) handleMessage OpenCV | GStreamer warning: your GStreamer installation is missing a required plugin

现在，这非常令人讨厌，因为我需要多次使用 VideoCapture 命令。在视频上尝试 tp.batch 命令（将 trackpy 导入为 tp）时，警告会变得更糟。
有什么方法可以阻止所有这些警告吗？
我尝试了以下方法：
os.environ["OPENCV_LOG_LEVEL"] = "SILENT" 、 和 None 都帮上了忙。tp.quiet()os.environ["OPENCV_LOG_LEVEL"] = "FATAL"warnings.filterwarnings('ignore').
