Hey y’all!

A few weeks ago, I started using Spacy to detect locations in job descriptions. Spacy is an NLP library that lets you do pretty powerful stuff out-of-the-box and get things done fast.

Everything was working fine locally. But NoiceJobs (my project) is hosted on Heroku and uses the cheapest dynos possible, with only 0,5GB of RAM. For running simple apps that’s enough, but ML code is normally more memory and CPU-intensive, so when I deployed the new version of the app on Heroku I’d get memory quota exceeded errors all the time.
