[Wannna build real-world ML products?](#wannna-build-real-world-ml-products)\n\n## What is this repo about?\nThis repository shows how to backfill historical OHLC feature in a Feature Store (Hopsworks) using an orchestration tool (Prefect).\n\n\n## How to run this code\n\n- Create a Python virtual environment with the project dependencies with\n    ```\n    $ make init\n    ```\n\n- Connect to your Prefect Cloud\n    ```\n    $ prefect cloud login \n    ```\n\n- Set environment variables necessary to talk to your Hopsworks feature store\n    ```\n    $ . ./set_hopsworks_credentials.sh\n    ```\n\n- Backfill OHLC data for a range of dates (e.g. from `2023-01-01` to `2023-01-31`)\n    ```\n    $ make from_day=2023-01-01 to_day=2023-01-31 backfill\n    ```\n\n## Wannna build real-world ML products?\n\nCheck the [Real-World ML Program](https://realworldmachinelearning.carrd.co/), a hands-on, 3-hour course where you will learn\nhow to design, build, [deploy](https://taxi-demand-predictor.streamlit.app/), and [monitor](https://taxi-demand-predictor-monitoring.streamlit.app/) complete ML products.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpaulescu%2Fbackfill-feature-store-with-prefect","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpaulescu%2Fbackfill-feature-store-with-prefect","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpaulescu%2Fbackfill-feature-store-with-prefect/lists"}
