Error loading the model (weights)

[Sung-IL Shim]

Hi, I have used encoder.py (v0.3) to get my weight changed to convert my own Keras model into .buf file, however when I am loading it, I get following error...............

Is it still because my Keras version was >2 ?

Help would be really really appreciated..

I solved my weights loading problems by modifying the python/encode.py file. Basically there is a name mismatch between h5 and what is encoded by that file, I think due to versions issues, but not sure. Anyway I pushed the fix to my repo https://github.com/NPolikurov/keras-js
