Dicom Client moved to…

Error message

Dicom Client moved to apache_beam.io.gcp.healthcare.dicomclient

What it means

Importing apache_beam.io.gcp.dicomclient warns that the DICOM client was relocated to apache_beam.io.gcp.healthcare.dicomclient. The old module only re-imports the new location (dicomclient and dicomio) and emits a DeprecationWarning.

Solutions

1. Change imports to `from apache_beam.io.gcp.healthcare.dicomclient import ...`.
2. Update IO references to `from apache_beam.io.gcp.healthcare import dicomio`.
3. Search for 'io.gcp.dicomclient' and remove all legacy imports.

Example fix

// before
from apache_beam.io.gcp.dicomclient import DicomClient
// after
from apache_beam.io.gcp.healthcare.dicomclient import DicomClient

    import apache_beam.io.gcp.dicomclient  # noqa
    if w:
        raise ImportError('Import from apache_beam.io.gcp.healthcare.dicomclient')

When it happens

Trigger: Any execution of `from apache_beam.io.gcp.dicomclient import ...` or plain import of that module.

Common situations: Healthcare DICOM pipelines written before the package reorganization; upgrades surfacing stale imports under io.gcp.
