In this example we export the model with an input of batch_size 1, but then specify the first dimension as dynamic in the dynamic_axes parameter in torch.onnx.export(). phoenix media

"WebMaking dynamic input shapes fixed . If a model can potentially be used with NNAPI or CoreML as reported by the model usability checker, it may require the input shapes to be made ‘fixed’. This is because NNAPI and CoreML do not support dynamic input shapes. For example, often models have a dynamic batch size so that training is more efficient. " - Onnx dynamic input
