Above Bold line is throwing the above keyerror when example_experiments weights are used but with new weights, it worked.

Can someone please upload correct weights?
I do not have a "decent machine" to run all 1000*1000 epoch iterations

Thanks

The Keras saving/loading functions have likely been changed since the weights file was created. Your options would be to downgrade Keras, try writing your own loading function that is backwards-compatible (not sure if possible) or rerun the training.
