How to deploy a tensorflow model in Heroku, within the free slug size available of 500MiB?

I have a Convolutional Neural Network model made in tensorflow 2.6. I wish to deploy it in free, Heroku plan. But Heroku free plan, only allows a maximum slug size of 500MiB. Is there any way I can host the model in the Heroku free plan?

My end goal is to build an API, which when passed with an image in base64 format, returns a label.

Answer

I found a solution.

Use tensorflow-cpu.

tensorflow-cpu is much smaller than tensorflow and can fit into the maximum permissible size of Heroku for free, which is 500MiB.
