[英]Having error in predictor = dlib.shape_predictor(“shape_predictor_68_face_landmarks.dat”) RuntimeError:
I'm keep running with error in line 8.我在第 8 行继续运行错误。
predictor = dlib.shape_predictor("shape_predictor_68_face_landmarks.dat") RuntimeError: Unable to open shape_predictor_68_face_landmarks.da
I downloaded the files I tried to add the files to working directory but PyCharm doesn't let me drag and drop anything.我下载了我试图将文件添加到工作目录的文件,但是 PyCharm 不允许我拖放任何东西。
import cv2
import numpy as np
import dlib
cap = cv2.VideoCapture(0)
detector = dlib.get_frontal_face_detector()
predictor = dlib.shape_predictor("shape_predictor_68_face_landmarks.dat")
def midpoint(p1 ,p2):
return int((p1.x + p2.x)/2), int((p1.y + p2.y)/2)
while True:
_, frame = cap.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
faces = detector(gray)
for face in faces:
#x, y = face.left(), face.top()
#x1, y1 = face.right(), face.bottom()
#cv2.rectangle(frame, (x, y), (x1, y1), (0, 255, 0), 2)
landmarks = predictor(gray, face)
left_point = (landmarks.part(36).x, landmarks.part(36).y)
right_point = (landmarks.part(39).x, landmarks.part(39).y)
center_top = midpoint(landmarks.part(37), landmarks.part(38))
center_bottom = midpoint(landmarks.part(41), landmarks.part(40))
hor_line = cv2.line(frame, left_point, right_point, (0, 255, 0), 2)
ver_line = cv2.line(frame, center_top, center_bottom, (0, 255, 0), 2)
cv2.imshow("Frame", frame)
key = cv2.waitKey(1)
if key == 27:
break
cap.release()
cv2.destroyAllWindows()
Solve the problem.解决这个问题。 I went in my Mac open pycharm install dlib and at first I had the same problem.
我进入我的 Mac 打开 pycharm 安装 dlib,起初我遇到了同样的问题。 the type in google shape_predictor_68_face_landmarks.dat.
google shape_predictor_68_face_landmarks.dat 中的类型。 search different option the best source: https://github.com/davisking/dlib-models/blob/master/shape_predictor_68_face_landmarks.dat.bz2 download the file and I dropped the file in sam
搜索不同选项的最佳来源: https://github.com/davisking/dlib-models/blob/master/shape_predictor_68_face_landmarks.dat.bz2下载文件,我将文件放入 sam
