Webbon Shape Inference Document. Another option to use dynamic shape feature is to export the model with dynamic dimension using Model Optimizer. OpenVINO Model Server will inherit the dynamic shape and no additional settings are needed. To the demonstrate dynamic dimensions, take advantage of: WebbWARNING: The shape inference of mmcv::grid_sampler type is missing, so it may result in wrong shape inference for the exported graph. Please consider adding it in symbolic function. warning怕什么，onnx转出来了，直接部署到服务器上生产！

WebbBoth symbolic shape inference and ONNX shape inference help figure out tensor shapes. Symbolic shape inference works best with transformer based models, and ONNX shape inference works with other models. Model optimization performs certain operator fusion that makes quantization tool’s job easier.
