after pip install pfilter, when I run the example_filter.py the error occured. 

cv2.error: OpenCV(4.6.0) D:\a\opencv-python\opencv-python\opencv\modules\dnn\src\layers\permute_layer.cpp:161: error: (-215:Assertion failed) (int)_numAxes == inputs[0].size() in function 'cv::dnn::PermuteLayerImpl::getMemoryShapes'
