Fix ArtifactNotFoundError

✅ Solution

ArtifactNotFoundError in DVC usually means a DVC-tracked file or directory is missing from your local workspace or remote storage. To fix this, first ensure the missing files are committed to DVC and the corresponding data cache exists; then, run `dvc pull` to download the missing artifacts from your remote storage into your local workspace. Finally, verify that the submodule data is also pulled.
