TypeError: Expected Ptr<cv::UMat> for argument 'M'

Dear George,

Thank you for sharing your face average project!

When trying to run:

python ./run.py -i "datasets/us-mp/president" -w -wt 200

I encountered the following error:

Namespace(ext=None, height=400, input='datasets/us-mp/president', noCaching=False, noWarps=False, output=None, template=None, width=300, window=True, windowTime=200) Faces detected: 1 in ...-regan.jpg: 100%|██████████████████████████████| 6/6 [00:00<00:00, 1238.66it/s] Loading: ...ident\ronald-regan.jpg: 100%|████████████████████████████████| 7/7 [00:00<00:00, 22.77it/s] Warping: ...sident\barak-obama.jpg: 0%| | 0/7 [00:01<?, ?it/s] Traceback (most recent call last): File "./run.py", line 27, in <module> Averager(width=options.width, height=options.height).run(path=options.input, ext=ext, window=options.window, showWarps=not options.noWarps, windowTime=options.windowTime, useCaching=not options.noCaching, template=options.template).save(name=options.output) File "./src\faceAverage.py", line 103, in run img = cv2.warpAffine(images[i], tform, (w,h)) TypeError: Expected Ptr<cv::UMat> for argument 'M'

I'm not entirely sure what's causing this to happen - anyways, regards!
