/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/perf_infer_gpu_one.md | https://huggingface.co/docs/transformers/en/perf_infer_gpu_one/#-optimum | .md | ONNX Runtime (ORT) is a model accelerator that supports accelerated inference on Nvidia GPUs, and AMD GPUs that use [ROCm](https://www.amd.com/en/products/software/rocm.html) stack. ORT uses optimization techniques like fusing common operations into a single node and constant folding to reduce the number of computation... | 3_9_1 |

You'll need to use an [`~optimum.onnxruntime.ORTModel`] for the task you're solving, and specify the `provider` parameter which can be set to either [`CUDAExecutionProvider`](https://huggingface.co/docs/optimum/onnxruntime/usage_guides/gpu#cudaexecuti... | 3_9_3 |
