How can I fetch these Version IDs and ETags in W&B?

If you log an artifact reference with W&B and enable versioning on the buckets, the version IDs appear in the Amazon S3 UI. To retrieve these version IDs and ETags in W&B, fetch the artifact and read the corresponding manifest entries. For example:

artifact = run.use_artifact("my_table:latest")
for entry in artifact.manifest.entries.values():
    versionID = entry.extra.get("versionID")
    etag = entry.extra.get("etag")
