Overview

Notebook sessions can use the same Python clients and tracking APIs as jobs and services. When a notebook runs in-cluster, Polyaxon resolves the project, run, API host, and scoped token from the runtime context. When a notebook runs outside Polyaxon, configure context with the CLI, environment variables, or explicit client arguments.

Multi-run tracking

Notebook sessions often need to track more than one run in a single kernel. Start each run explicitly, end it, then start the next one:

from polyaxon import tracking

# Start run1
tracking.init(name="run1", is_new=True)

# ...

# End run1
tracking.end()

# ...

# Start run2
tracking.init(name="run2", is_new=True)

# ...

# End run2
tracking.end()

If the notebook runs in-cluster, context is resolved automatically. If it runs outside Polyaxon, see instantiation for context options.
