Hi @catchymz,
Usually this seems to be a caching problem in the environment. Can you try again after restarting the runtime?

Again after restarting it works today, but yesterday after restarting still don’t work! Thanks!

but can’t show the GRIDS for me, as in the course video

Please refer this thread
