 If using the python API, it's better to initiate tf32 yourself; see [here](https://huggingface.co/docs/transformers/perf_train_gpu_one#tf32) for how.
 
-Here are some suggestions for additions to the README in order to reflect the latest changes in the `__init__` method of your `Summarizer` class:
-
 ### Using Optimum ONNX Runtime
