I'm having trouble converting the nbeatsx model to the onnx model.
When running the to_onnx() method of the nbeatsx model, the NBEATSx.forward() method will be run, this method needs to provide windows_batch parameters, but TimeSeriesDataset cannot provide this parameter, how to solve this problem?
