@miwojc what is the size of it? Do you need all the functionality?
Make a new thread and tag me in it, along with the people who hearted your post. Although, please note that I haven’t done too much with the Heroku platform as I run my own servers.
[Possible suboptimal option:] Your experience would probably be best with the entire install, but you probably don’t actually need any of the notebook or fancy parts - and might be fine if you are purely running a deployment you don’t intend on working on anymore - but I think it would defeat the learning experience in the class.
You can also look at https://forums.fast.ai/t/setup-help/65529 to see how other platforms have setup their images. If you get it working, post your image script there too so others can use it who would prefer Heroku. If you just want a working solution though, the paperspace platform may be a comparable substitute: https://forums.fast.ai/t/platform-paperspace-free-paid-options/65515 .
