Unsupported activation: relu in function 'cv::dnn::darknet::ReadDarknetFromCfgStream'

[oliviaolivia700]

modelConfiguration = "C:/Users/olivia lai/Downloads/poseEstimation/OpenPose-Multi-Person/pose/darknet/openpose.cfg"
modelWeights = "C:/Users/olivia lai/Downloads/poseEstimation/OpenPose-Multi-Person/pose/darknet/openpose.weight"
darknet = cv2.dnn.readNetFromDarknet(modelConfiguration, modelWeights)

And then I got this error

error Traceback (most recent call last)
in ()
----> 1 darknet = cv2.dnn.readNetFromDarknet(modelConfiguration, modelWeights)

error: OpenCV(4.0.0) C:\projects\opencv-python\opencv\modules\dnn\src\darknet\darknet_io.cpp:552: error: (-212:Parsing error) Unsupported activation: relu in function 'cv::dnn::darknet::ReadDarknetFromCfgStream'

Please help. Thanks so much for your work =D

I think OpenCV prompted this error because relu could not be used as an activation function in convolutional layers???
