OpenPose pretrained network not working

I'm trying to use the MATLAB openPose example but it is again showing an error. Has anyone successfully used it? Has the bug been fixed?

dataDir = fullfile(tempdir,'OpenPose');

trainedOpenPoseNet_url = 'https://ssd.mathworks.com/supportfiles/vision/data/human-pose-estimation.zip';

downloadTrainedOpenPoseNet(trainedOpenPoseNet_url,dataDir)

unzip(fullfile(dataDir,'human-pose-estimation.zip'),dataDir);

Unrecognized function or variable 'downloadTrainedOpenPoseNet'.

anyone?
