Practical overview
When it fits
Use it when you want to inspect or adapt a documented recommender-system workflow built around MovieLens, rather than simply call a hosted recommendation API.
Who it is for
- Developers learning how recommender-system components connect from offline processing to online serving.
- Teams prototyping a recommendation workflow with retrieval, feature storage, model ranking, and inference components.
Documented uses
- Prepare MovieLens ratings and interaction history for offline training and evaluation.
- Generate term-based and vector-based recommendation candidates.
- Train a ranking model and connect ranking features to inference components.
- Study a local example that combines a Flask web server with containerized supporting services.
Requirements & limits
The project materials are in a public repository described as open source. The README documents local Conda and Docker setup.
- The example uses MovieLens and converts ratings into implicit-feedback labels for its workflow.
- The ranking implementation is described as a sparse FM module combined with a dense MLP; despite the DeepFM label, it is not a conventional DeepFM structure.
- The documented stack separates offline Python work in Conda from Redis, Elasticsearch, Feast, and Triton services in Docker.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up the documented offline Conda environment
Create the Python environment used for offline preprocessing and model training.
Before you start
- Conda
- The repository checkout, including requirements.txt
- Internet access to install the listed packages
Steps
Create a Conda environment with Python 3.8 using the README's command.
Activate the rsppl environment.
Install packages from requirements.txt using the Anaconda and conda-forge channels.
Expected outcome
A Conda environment prepared for the repository's offline data processing and model training stages.
Guide limitations
- This setup guide does not cover running preprocessing, training, Docker services, or the web application.
