onnx-simplifier
ONNX Simplifier improves ONNX model performance by simplifying computational graphs through constant folding, replacing redundant operators with constant outputs. It is accessible as both an online tool and a Python package, requiring no installation for browser use and easy integration with the `onnxsim` command. Many projects like MXNet, MMDetection, and YOLOv5 use ONNX Simplifier for better model efficiency.
