ONNX, onnx,

[yyyyyxie]

It seems that I can only export ONNX with a fixed input size. I hope to set the width and height as dynamic axes. However, after setting, the exported ONNX can still only use the original width and height as the unique input shape.

If I use inputs of different sizes, it will throw an error similar to the one shown in the image. I've spent a lot of time and it seems that I haven't solved this problem.

Code:
dynamic = {'inputs': {2: 'h', 3: 'w'}, 'outputs': {2: 'h', 3: 'w'}}
torch.onnx.export(model, (img,), output_path, verbose=False,
opset_version=17, input_names=['inputs'], output_names=['outputs'], dynamic_axes=dynamic)
