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('jGkh6UREm4ZS0000'), started new Run('rhSqnGGg...') at 2025-05-28 14:18:51 UTC

• recommendation: to identify the script across renames, pass the uid: ln.track("jGkh6UREm4ZS")

Artifact(uid='xEo4V1zcuRqLROGJ0000', 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=2025-05-28 14:18:53 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/4AYJo7yp2O56hFeL0000.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()

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/4AYJo7yp2O56hFeL0000.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/52faa4b9739a9580db7f9e2720958644fd37efdd0478814572c2db1cb6e6a50c.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()
