Python 我正在用OpenCV制作蒙面人脸检测应用程序,用于检测戴面具的人脸,但我遇到了一个错误
是否有任何模块需要导入 还是全部正确导入 我不调试它 我重新格式化了一次文件 我已经得到了所有需要的xml和jpg文件 我已经导入了所有需要的模块。。。我想是的 下面是错误 你能帮我吗?我是OpenCV的新手,遇到了这样一个复杂的错误 感谢Stackoverflow社区的所有帮助:)Python 我正在用OpenCV制作蒙面人脸检测应用程序,用于检测戴面具的人脸,但我遇到了一个错误,python,opencv,face-detection,face,Python,Opencv,Face Detection,Face,是否有任何模块需要导入 还是全部正确导入 我不调试它 我重新格式化了一次文件 我已经得到了所有需要的xml和jpg文件 我已经导入了所有需要的模块。。。我想是的 下面是错误 你能帮我吗?我是OpenCV的新手,遇到了这样一个复杂的错误 感谢Stackoverflow社区的所有帮助:) C:\Users\Toshiba\Desktop\python\u temelleri\venv\Scripts\python.exe C:/Users/Toshiba/Desktop/python\u temel

您可能没有提供模型,或者模型的路径不正确。打印prototxtPath和weightsPath的值,以检查您是否提供了正确的模型路径。您是否阅读了错误消息?否。即使我在函数“cv::dnn::ReadProtoFromTextFile”中“无法打开”face\u detector\deploy.prototxt”,我也不理解任何内容好的。谢谢:):):):)::):):::)::)::)::):)::)::)::)::):):):):):):):):):):):):):):):):)谢谢你的回答:))))))(谢谢你的回答:)(谢谢你的回答:)(我不能投我的票,谢谢你!声誉低于15的人所投的票将被记录,但不会改变公开显示的帖子分数。”。
