-#### ONNX Runtime
-
-To train transformers with ONNX Runtime's acceleration features, 🤗 Optimum provides a `ORTTrainer` that is very similar to the 🤗 Transformers [Trainer](https://huggingface.co/docs/transformers/main_classes/trainer). Here is a simple example:
-
-```diff
-- from transformers import Trainer, TrainingArguments
-+ from optimum.onnxruntime import ORTTrainer, ORTTrainingArguments
-
-  # Download a pretrained model from the Hub
-  model = AutoModelForSequenceClassification.from_pretrained("bert-base-uncased")
-
-  # Define the training arguments
-- training_args = TrainingArguments(
-+ training_args = ORTTrainingArguments(
-      output_dir="path/to/save/folder/",
-      optim="adamw_ort_fused",
-      ...

-- trainer = Trainer(
-+ trainer = ORTTrainer(
-      model=model,
-      args=training_args,

-+     feature="text-classification", # The model type to export to ONNX
-      ...
-  )
-
-  # Use ONNX Runtime for training!

 ## Out of the box ONNX export
 
 The Optimum library handles out of the box the ONNX export of Transformers and Diffusers models!
