Hey,

free version of Heroku provides only 500mb of data, and it is difficuilt to host tensorflow heavy model in heroku.

But when I deployed it in Heroku it shows only 167 Mb consumed

The requirements takes only 167mb, but when it is actually running it takes more than 500mb
That’s why it is not possible to deploy image captioning on heroku

ohk thanks for your support
