python face_recognition库中使用其他的功能都可以正常运行，但只有用face_encodings会报错？

Question

已正确安装dlib和face_recognition库

代码如下：

import face_recognition

face_recognition.face_encodings("F:/multi-media/video frames/260.png")

报错如下：

PS F:\multi-media> & C:/Users/ONE7/AppData/Local/Programs/Python/Python37/python.exe "f:/multi-media/vedio analysis.py"

face_encodings中参数错误，应该直接放image = face_recognition.load_image_file("1.jpg")

我的也报错了，但是我的是RuntimeError: The full_object_detection must use the iBUG 300W 68 point face landmark style.这个错误，不知道怎么回事，调用face_encodings错误，其他的都没问题
