!lamin close

💡 no instance loaded

import lamindb as ln
import pytest

❗ To use lamindb, you need to connect to an instance.

Connect to an instance: `ln.connect()`. Init an instance: `ln.setup.init()`.

If you used the CLI to set up lamindb in a notebook, restart the Python session.

If you try to use lamindb, it will raise an InstanceNotSetupError and ask you to init or load an instance via the python API.

with pytest.raises(ln.InstanceNotSetupError):
    ln.track()

ln.setup.init(storage="./testsetup")

💡 connected lamindb: testuser1/testsetup

Now we can access functionality:

ln.settings.transform.stem_uid = "2lhqA4uTKSFP"
ln.settings.transform.version = "0"
ln.track()

Let us try to init another instance in the same Python session: It doesn’t work.

with pytest.raises(RuntimeError):
    ln.setup.init(storage="./testsetup2")

!lamin delete --force testsetup

💡 deleting instance testuser1/testsetup

💡 not deleting instance from hub as instance not found there
