Web22 de jul. de 2024 · Description I am trying to convert a Pytorch model to TensorRT and then do inference in TensorRT using the Python API. My model takes two inputs: left_input and right_input and outputs a cost_volume. I want the batch size to be dynamic and accept either a batch size of 1 or 2. Can I use trtexec to generate an optimized engine for … Web12 de out. de 2024 · Changing the batch size of the ONNX model manually after exporting it is not guaranteed to always work, in the event the model contains some hard coded shapes that are incompatible with your manual change.
