As @8li pointed out, the current code is incompatible with keras 2 due to the `layer_from_config` in [NGF/layers.py](https://github.com/keiserlab/keras-neural-graph-fingerprint/blob/92a5807/NGF/layers.py). Investigate what other issues arise when using keras 2 and see if we can fix them in a backwards-compatible manner.
