**Description**: Support new feature of TVM Virtual Machine (method `set_outputs`) on TVM Execution Provider side. It allows to avoid excess copying from TVM EP output tensor to ONNX Runtime one **Motivation and Context** Tests with multiple output topologies and big output tensors shows that there is overheads spent on copying from TVM EP to ONNX Runtime. Returning output(s) on preallocated memory for VirtualMachine was implemented on TVM side. **Details** `set_output_zero_copy` provider option for TVM EP switches on/off this feature. It is true by default. The feature works for both GraphExecutor and VirtualMachine from TVM. --------- Co-authored-by: Valery Chernov <valery.chernov@deelvin.com> |

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
