This pull request addresses a warning message that appears when using the `nlpconnect/vit-gpt2-image-captioning` model. The warning suggests updating the `preprocessor_config.json` file to use `image_processor_type` instead of `feature_extractor_type`.
Changes made:
- Renamed `feature_extractor_type` to `image_processor_type` in `preprocessor_config.json`.
This change should help to align the model's configuration with the latest practices in the `transformers` library and remove the warning message for users of the model.
