How to use a TensorFlow 1.13.0 model with WebDNN?

I'm using TensorFlow 1.13.0 / Keras 2.2.4 to generate my model. However, when using WebDNN to export it, I'm getting the error

    NotImplementedError: WebDNN supports TensorFlow >=v1.2.0,<=v1.4.0 Currently, TensorFlow 1.13.1 is installed.

How can I convert my model data to a format suitable for WebDNN?

Or is it possible to adapt WebDNN so that it works with TensorFlow 1.13.0?
