evaluation result changes after `datasets` version change
COLLABORATOR
Hi! The GH/no-namespace datasets versioning is synced with the version of the `datasets` lib, which means that the `wikiann` script was modified between the two compared versions. In this scenario, you can ensure reproducibility by pinning the script version, which is done by passing `revision="x.y.z"` (e.g. `revision="2.2.0"`) to `load_dataset.`
