Specify cross-project dependencies

In this guide, we will walk through specifying cross-project experiment dependencies. This feature can be useful if you have multiple linked projects.

To specify an upstream experiment dependency, you can add an entry to the dependencies list in your experiment. Add an experiment with the format <PATH_TO_PROJECT_JSON>|<SLUG>. So, if you created an experiment in other-project.json at 9:30 AM on Jan 1, 2022 with the name “My experiment”, you would have

[
    {
        ...,
        "dependencies": [
            "other-project.json|my-experiment-20220101093000"
        ],
        "name": "Base performance",
        "short_slug": "base-performance",
        "slug": "base-performance-<TIMESTAMP>",
        ...
    }
]

Important

The path to other-project.json is relative to the path to the current project JSON.

When you load the experiment through lazyscribe.Project, the dependencies will be accessible through a dictionary, using the short_slug as a key:

from lazyscribe import Project

project = Project(..., mode="r")
exp = project["base-performance"]

assert "my-experiment" in exp.dependencies

You can also add a dependency in python:

from lazyscribe import Project

myproject = Project(..., mode="w+")
otherproject = Project(...)

exp = myproject["base-performance"]
exp.dependencies["my-experiment"] = otherproject["my-experiment"]
