minimal heroku deployment

[naraugialusru]

Is there a simply way to deploy a trained lighting module on heroku so that it is as small as possible?

Naively pushing my model and app code yields a heroku slug that is about 1G. I'd like it to be less than 500M.

With pytorch, I solved a similar problem by using a lightweight wheel (in this case, https://download.pytorch.org/whl/cpu/torch-1.7.1%2Bcpu-cp36-cp36m-linux_x86_64.whl) instead of the full pytorch package.
