luigi.tools.deps_tree module

This module parses commands exactly the same as the luigi task runner. You must specify the module, the task and task paramters. Instead of executing a task, this module prints the significant paramters and state of the task and its dependencies in a tree format. Use this to visualize the execution plan in the terminal.

$ luigi-deps-tree --module foo_complex examples.Foo
