Experience
- ML Server with ZIOhttps://github.com/bartchodnicki/zio-ml-server
This is an example of how to create an HTTP server for serving ML prediction with the ZIO HTTP library and MLeap. It enables the use of machine learning models made in Python or Spark with Scala applications. The project shows how to load the ML model saved in a file and use it to make predictions for incoming HTTP requests.
