ProjectFlow

Inherit from ProjectFlow instead of Metaflow’s FlowSpec:

from obproject import ProjectFlow

class MyFlow(ProjectFlow):
    @step
    def start(self):
        self.prj.register_data("dataset", "data")
        self.next(self.end)

Configuration

ProjectFlow reads configuration from two files: obproject.toml: Project identity and settings.

project = "fraud-detection"

[dev-assets]
branch = "main"  # Read assets from main branch during local dev

[dependencies]
include_pyproject_toml = true  # Auto-apply pyproject.toml deps (default: true)

pyproject.toml: Python dependencies applied through @pypi_base.

[project]
dependencies = [
    "scikit-learn>=1.3.0",
    "pandas>=2.0.0",
]
