I am trying to perform my custom object detector using the Intel Movidius Neural Compute Stick 2. The network that I am using is based on YOLO, and therefore has the graph structure saved as a .cfg file and the weights as a .weights file. I use OpenCV which was installed with Openvino.
More information :
- Operating System -> Ubuntu 18.04.3 LTS
- OpenCV => 4.1.2
My code is here :
import cv2 as cv
modelConfiguration_big = "yolov3.cfg"
modelWeights_big = "yolov3.weights"
# load network
net = cv.dnn.readNetFromDarknet(modelConfiguration_big, modelWeights_big)
net.setPreferableBackend(cv.dnn.DNN_BACKEND_INFERENCE_ENGINE)
net.setPreferableTarget(cv.dnn.DNN_TARGET_MYRIAD)
# perform inference
frame = cv2.imread('img_path.jpg')
blob = cv.dnn.blobFromImage(frame, 1/255, (inpWidth, inpHeight), [0,0,0], 1, crop=False)
net.setInput(blob)
outs = net.forward(getOutputsNames(net))
On running the code, I get the following error:
Traceback (most recent call last):
File "Detector_1.py", line 236, in <module>
outs = net_big.forward(getOutputsNames(net_big))
cv2.error: OpenCV(4.1.2-openvino)
