No attribute error.

First of all, that code is very useful. Thanks a lot for that. Secondly, I had a look over your code. I am implementing Video Classification task over a data set named UCF101. I was able to store the frames successfully. However, it throws error while creating an instance of DualOpticalFlow_TVL1 module.

Module 'cv2.cv2' has no attribute 'createOptFlow_DualTVL1'

I have all the packages installed and updated. Did you face this error before? If yes, how did you resolve it?

I haven't met this error. I have googled, seems like a version problem. You can have a try.

Hello, everyone ! As the qijiezhao said, the problem is accossiated with the version of opencv-python , your version must be 3.x , try again!

If you (like me) are using cv2 version '4.1.0', then do the following

Replace dtvl1=cv2.createOptFlow_DualTVL1()

with dtvl1=cv2.optflow.DualTVL1OpticalFlow_create()

This worked for me. Thank you
