face_recognition problem with face_encodings function
问题
我是一个新手，遇到了解决这个问题的困难。
我尝试运行来自face_recognition的示例代码，使用网络摄像头。这两个示例都不适用于我，并且一直抛出这个错误。
我正在使用 Windows 11 上运行的 Python 3.11.2。我已经安装了 face_recognition v1.3.0 和 dlib v19.24.1。
我已经尝试按照 face_recognition 的安装指南重新安装了所有内容。

I am a newbie and having difficulty on resolving this issue.
What I am trying to do is run the sample code from face_recognition using a webcam. Both of the two example doesn't work on me and keeps on throwing this error.

I am using Python 3.11.2 running on Windows 11. I have face_recognition v1.3.0 and dlib v19.24.1.
I already tried reinstalling everything based on the installation guide from face_recognition.
答案1
得分: 5
请用以下代码行替换：
rgb_small_frame = numpy.ascontiguousarray(frame_process[:, :, ::-1])
英文:
Please replace the code line,
rgb_small_frame = frame_process[:, :, ::-1]
with below code line,
rgb_small_frame = numpy.ascontiguousarray(frame_process[:, :, ::-1])
答案2
得分: 0
rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)
your code worked bex
英文:
This is the answer
rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)
your code worked bex
