Contribute to tensorflow/tensorrt development by creating an account on GitHub. But when using trtexec --shapes, you should provide the real shape for inference as --shapes should use real dimension, not -1. Implemented modules to convert Pytorch -> ONNX -> TensorRT, with dynamic shapes (multi-size input) inference. At first when I flashed the JETPACK 4. you should observe the inference time is dropping to normal. alexnet with torchvision. What's the criteria to decide if an op supports dynamic shape or not? supports_dynamic_shape specifies if a converter's implementation handles dynamic shape properly; For some existing ops, which are not marked as supports_dynamic_shapes=True, can I write a converter that wraps the existing converter, and mark my own converter with high priority? Shape Tensors are the method to encode dynamic shape information in TensorRT so this is necessary to add true support for dynamic shape. 5. INetworkDefinition 这些 For instance, if a model has no graph breaks and compiles successfully with the Torch-TensorRT backend, then that model should be compilable and serializeable via the torch_tensorrt Dynamo IR, as discussed in Dynamic shapes with Torch-TensorRT.
