face_encodings函数的face_recognition问题

Question

我是新手，很难解决这个问题。

我想做的是使用网络摄像头运行来自 face_recognition 的示例代码。这两个示例都不适用于我，并且不断抛出此错误。

我正在使用在Windows 11上运行的Python 3.11.2。我有face_recognition v1.3.0和dlib v19.24.1。

我已经尝试根据face_recognition的安装指南重新安装所有内容。

Answer 1

请更换代码行，

rgb_small_frame = frame_process[:, :, ::-1]

使用下面的代码行，

rgb_small_frame = numpy.ascontiguousarray(frame_process[:, :, ::-1])

Answer 2

这就是答案

rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

你的代码工作得很好

Answer 3

任何人都可以告诉我到底应该在哪里进行更改，因为我找不到提到的 rgb_small_frame 行。谢谢你
