There is but it's a udemy course unfortunately. I don't want to spam the group with links but the link is on the lat page of the document
https://www.udemy.com/course/vector-databases-deep-dive/?cou...
I already have a Udemy account so when I went to checkout and logged in it said the promo was for new users only. But I went back to the course page again and reloaded the page so that I was logged in and then I was able to buy it with the coupon applied.
