# step¶

Every step defines a separate type of execution such as training or evaluation.

Here is an overview of the five valid step properties:

• name: name of the step such as “feature-extraction” or “model-training”
• environment: (optional) default environment slug that specifies hardware and location e.g. “aws-eu-west-1-g3s-xlarge”
• image: default Docker image that will be used as the runtime environment
• command: one or more commands that are ran during execution
• inputs: (optional) files available during execution
• parameters: (optional) valid parameters that can be passed to the commands
