What is ONNX Runtime for PyTorch
ONNX Runtime for PyTorch gives you the ability to accelerate training of large transformer PyTorch models. The training time and cost are reduced with just a one line code change.
- One line code change: ORT provides a one-line addition for existing PyTorch training scripts allowing easier experimentation and greater agility.
from torch_ort import ORTModule
model = ORTModule(model)
-
Flexible and extensible hardware support: The same model and API works with NVIDIA and AMD GPUs; the extensible "execution provider" architecture allow you to plug-in custom operators, optimizer and hardware accelerators.
-
Faster Training: Optimized kernels provide up to 1.4X speed up in training time.
-
Larger Models: Memory optimizations allow fitting a larger model such as GPT-2 on 16GB GPU, which runs out of memory with stock PyTorch.
-
Composable with other acceleration libraries such as Deepspeed, Fairscale, Megatron for even faster and more efficient training
-
Part of the PyTorch Ecosystem. It is available via the torch-ort python package.
-
Built on top of highly successful and proven technologies of ONNX Runtime and ONNX format.
ONNX Runtime Training Examples
This repo has examples for using ONNX Runtime (ORT) for accelerating training of Transformer models. These examples focus on large scale model training and achieving the best performance in Azure Machine Learning service. ONNX Runtime has the capability to train existing PyTorch models (implemented using torch.nn.Module) through its optimized backend. The examples in this repo demonstrate how ORTModule can be used to switch the training backend.
