Can I disable tracking run inputs?¶

Yes, if you switch track_run_inputs to False.

# !pip install 'lamindb[jupyter]'
!lamin init --storage test-run-inputs

import lamindb as ln

→ connected lamindb: testuser1/test-run-inputs

Some test artifacts:

ln.track(transform=ln.Transform(key="Dummpy pipeline"))
ln.Artifact(ln.core.datasets.file_jpg_paradisi05(), description="My image").save()
ln.Artifact(ln.core.datasets.file_mini_csv(), description="My csv").save()

→ created Transform('ICt6P1HkFxv30000'), started new Run('J3MA6q2N...') at 2025-06-30 16:35:24 UTC

• recommendation: to identify the script across renames, pass the uid: ln.track("ICt6P1HkFxv3")

Artifact(uid='jQ2REstOI6RnM6RL0000', is_latest=True, description='My csv', suffix='.csv', size=11, hash='z1LdF2qN4cN0M2sXrcW8aw', branch_id=1, space_id=1, storage_id=1, run_id=1, created_by_id=1, created_at=2025-06-30 16:35:26 UTC)

Call ln.track():

ln.track("Rx2s9aPTMQLY0000")

Don’t track artifact as run input¶

ln.settings.track_run_inputs = False

artifact = ln.Artifact.get(description="My image")

artifact.cache()

PosixUPath('/home/runner/work/lamindb/lamindb/docs/faq/test-run-inputs/.lamindb/vA5fU3Iizfe7T6O50000.jpg')

No run inputs are linked to the current notebook run:

ln.Run.get(id=ln.context.run.id).input_artifacts.all()

<ArtifactBasicQuerySet []>

artifact.view_lineage()

../_images/fc2c39eb792f89273e7080f93a487db35b5b2543b88d946a31e17ac0f5001eee.svg

Manually track artifact as run input¶

Let us manually track an artifact by passing is_run_input to either .cache(), .load() or .open():

artifact.cache(is_run_input=True)

PosixUPath('/home/runner/work/lamindb/lamindb/docs/faq/test-run-inputs/.lamindb/vA5fU3Iizfe7T6O50000.jpg')

You can see the fcs artifact is now being added to the run inputs:

for input in ln.Run.get(id=ln.context.run.id).input_artifacts.all():
    print(input)

artifact.view_lineage()

../_images/4b9b6612fa607264efb492f726f6ae11583a5691c72d811aa94ba198947e6693.svg

Automatically track artifacts as run input¶

If you switch the following setting, and call to .load(), .cache() and .open() will track the artifact as run input.

ln.settings.track_run_inputs = True

artifact = ln.Artifact.get(description="My csv")

artifact.load()

	test
0	1
1	2
2	3

for input in ln.Run.get(id=ln.context.run.id).input_artifacts.all():
    print(input)

artifact.view_lineage()
