Source Code: GitHub
Last year, I launched Skim with my friends. It is a platform to find, manage and read research papers. The platform is powered by machine learning models for use cases like finding related papers and classifying research areas/tasks of the paper. At Skim, we use GitHub for most of our development, testing, integrations and releases. We also use GitHub Actions for carrying out small jobs using workflows. A point to remember, Skim is in BETA and built end-to-end totally for free. Thanks to services like GitHub, Fly and MongoDB.
When it comes to model deployment and running inference, we experimented with several options. From the beginning we were looking for a free alternative for our small-scale experiments. For example, post-training of the NLP models, we tried saving the weights and embeddings on cloud e.g. Dropbox, Google Drive and other similar services. This turned out very complicated due to their apps & tokens and their storage limits. From an integration perspective, this was not easy to maintain for developers. As mentioned earlier from a pricing perspective, something like Amazon S3 wasn’t enough for us to sustain. This paved the way to think of a solution can be closer to our version control system, easier when it comes to integration and also free!
From the context above, it is clear that every small-scale startup, open source project or self-hosted ML solutions go through following set of challenges:
We need a simple solution for tackling these challenges that will requires less time and hustle to setup and integrate.
GitHub Releases are one of the best features because it allows you to release a version of your codebase along with some release assets. Now these assets doesn’t need to be part of your codebase, but it can be output of it. For example, a project can build & release distributions for each operating system. Similarly, we can use GitHub to release a version with our model weights, other artifacts, etc. Inspired by this simple idea, GaAMA was born. It does exactly as it stands for - GitHub as Artifactory for Model Artifacts. One can create a release of their repository on GitHub and upload their final outputs of training to those releases. Keep in mind, GitHub acts as a kind of simple model registry for you.
For both use cases as mentioned below, one has to install and initialize GaAMA.
Install GaAMA using:
pip install gaama
Initialize GaAMA with github credentials:
from gaama import GaAMA
gaama = GaAMA(username='<username>', password='<password or token>', owner='<github_repo_owner>', repository='<github_repo_name>')
A developer or a team who trains a model on Google Colab (or similar service) wants to release a version
gaama.publish(tag='<release version>', files=['model.pt', 'embeddings.npy'])
With just one line of code, you will be able to release & publish model of your choice!
A software engineer who is building a user-centric service, wants to load the model and run inference
With just one line of code, you will be able to download the model of your choice on your production server!
You can also refer to this example notebook demonstrating the publish and download model artifacts with a PyTorch model.
