Agree. But it can be easily resolved at least with linked discussions about problems&solutions on this forum for instance. Just one button on the page “Got stuck, but found a solution? Tell us more” or so. I saw the same on the other platform. Or just a little checklist, like..there are may appear some problems. Check you have Pro status to use HF Inference API, check deploy button etc etc
Without claims to authors, always there are ways to make a course better
Thanks for you help!
