applying MSDDetector in colab

Question

I have trouble writing the MSD detector correctly. However, it has no attribute ''create''.

I wrote the following code. But my session crashed for an unknown reason. msd=cv2.xfeatures2d.MSDDetector() kps1=msd.detect(I1) I will appreciate any help.

    CV_WRAP static Ptr<MSDDetector> create(....
