ValueError: total size of new array must be unchanged when loading model

[ChuanWang90]

Hi, I get the following error when loading the json model. I have tried in both Keras vs 1 and 2 and I run with Theano as backend.

Update: If I run the build_model.py script I get the same error.

Same issue. Any solution?

[Metal-joker]

Okay, I saw the solution in #7 issue.
