Custom model assembly¶
While DataRobot provides hundreds of built-in models, there are situations where you need preprocessing or modeling methods that are not currently supported out of the box. To create a custom inference model, you must provide a serialized model artifact with a file extension corresponding to the chosen environment language and any additional custom code required to use the model.
Before adding custom models and environments to DataRobot, you must prepare and structure the files required to run them successfully. The tools and templates necessary to prepare custom models are hosted in the Custom Model GitHub repository. (Log in to GitHub before clicking this link.) DataRobot recommends understanding the following requirements to prepare your custom model for upload to the Custom Model Workshop.
