Can anyone tell me where am I wrong or it's not my problem?I cloned whole the files from huggingface. Is it can be fixed? I would appreciate for any suggestion. Thank you.

Did you put the `--version_2_with_negative` flag to specify you're using SQuAD V2?<|||||>This issue has been automatically marked as stale because it has not had recent activity.
