Web24 de out. de 2024 · I have INNX model converted from Tensorflow pb so the format is NHWC format. To convert to TensorRT I like to change to NCHW format. How can I change in ONNX? WebLet’s look at a simple scenario to understand the complications that arise due to different layouts - Suppose we want to compile a Tensorflow NHWC graph for an ARM edge device. But, suppose we currently support only NCHW schedules in TOPI for ARM. So, there is a mismatch between framework layout and TOPI-supported layout.
