How to use progress bar to show python function progress in Django?

Question

I created a site where the user uploads the video, and I process the video frame by frame using the python function. In this function, I know how many frames I have already processed. And I want to show the progress to users in the progress bar. I googled a lot, but almost all progress indicators are loading, so how can I implement this? Thank!
