@litaotao, there should be a way to link the slidechange event with the execution of the cells... but that's probably not trivial and need customization... probably it could be done as an RISE extension/plugin? :wink:
about the screenshot... I would need to see the ipynb to check where could be the problem... can you share it?
@litaotao based on your screenshot: is it possible that you didn't edit the metadata of the cells to indicated the slides (it looks like it is interpreted as one huge slide). You have to do 'Cell toolbar' -> 'Slideshow' and then indicate which cells should be slides.
