Model_hub built on top of fastapi and mongodb

Features

• Docker image with mongodb and fastapi local install

• Ability to create one model with the following payload: { "_id": "6223f652abc1bffae909c245", "name": "ensemble_model", "model_url": "/saikat/testing/model", "description": "model_description", "version": "model_version", "ludwig_version": "1.0", "author": "saikat", "namespace": "ns_model" } Due to mongodb creating internal id you only need to specify the rest of the fields Sample url is an http POST action with the following url: http://localhost:8000/api/models with the above parms except id passed in as json

• Ability to retrieve all the models, sample url is here GET http://localhost:8000/api/models

• Ability to retrieve one model based on the model_url , sample url is here GET http://localhost:8000/api/models/one/model?model_url=/saikat/testing/model

Installation and usage

• Create env from template: cp example.env .env (only once), this will create a path for the local mongodb collection
• Run docker stack docker-compose up --build to build the image and run both fastapi and mongodb locally and then access using the endpoints above

FastAPI Bug with retrieving a single model based on model_url

• For retrieving a model based on the model_url we need to come up with a better url structure but wont be able to use path params due to the fact that they contain slashes, issue documented here: fastapi/fastapi#1750

TODO

• Delete
• Setup mongo and fastapi instance on linux foundation
• Make the get based on model_url have a better url structure
• unit tests
• end to end integration tests
• local testing by ludwig committers--bug fixes due to this
