unable to load VQA model from json string #2

hi I am unable to load the model from json string. I am using keras 1.0.1 version. I am getting KeyError: class_name

Hi Suraj This was written in Keras 0.3.2 (the previous version). The new version of Keras (1.-+) changed the way it represents a model. This means model built in older versions will not be loadable without some changes.

It seems they might add the legacy support to load old models, see this https://github.com/fchollet/keras/blob/master/keras/models.py#L26

However, I will try to compile the model in newer version, but training will take time. Give me a day or two. In the meantime you could easy have a alternate directory of older version of keras and use that to run this.

@suraj-deshmukh I have pushed the code which should work on Keras 1+
