The infer_shape function of CustomOpProp has an in_shape parameter. You can use it to calculate the output_shape dynamically.

If you cannot infer input shape without input data, but can infer maximum shape, then you can use it as commented here: https://github.com/apache/incubator-mxnet/issues/9758
