使用yolo运行Opencv时出现问题：“AttributeError:模块'cv2.dnn'没有'dnn\u targetg\u CPU'属性”

Question

当我试图通过jupyter笔记本上的yolo3运行以下代码进行目标检测时：

classfile = "coco.names"
classes = []
wht = 320

with open(classfile,"rt") as f:
classname = f.read().rstrip("\n").split("\n")

modelconfiguration = "yolov3.cfg"
modelweight = "yolov3.weights"

net = cv2.dnn.readNetFromDarknet(modelconfiguration,modelweight)
net.setPreferableBackend(cv2.dnn.DNN_BACKEND_OPENCV)
net.setPreferableTarget(cv2.dnn.DNN_TARGEGT_CPU)

在最后一行net.setPreferableTarget(cv2.dnn.DNN_TARGEGT_CPU)导致下面的错误

    AttributeError: module 'cv2.dnn' has no attribute 'DNN_TARGEGT_CPU'

我已经尝试升级opencv，但这并没有解决问题

Answer 1

我认为这只是一个打字错误。尝试将最后一行替换为：

net.setPreferableTarget(cv2.dnn.DNN_TARGET_CPU)

打字错误当然是拼写TARGET为TARGET

以下是Opencv DNN目标的列表：https://docs.opencv.org/master/d6/d0f/group__dnn.html#ga709af7692ba29788182cf573531b0ff5
