Finetune error: layer keras_layer expects 262 weights, but the saved weights have 260 elements #77

I want to feed more samples base on trained model, to do some fine tune. But I got Error:

Same error happening to me. I can fine tune other models like Keras 299x299 Image Model, but I can't make it work on Latest Models Zip (v1.1) The only way I can make this v1.1 version model working is if I drop the option do_fine_tuning but it drops the model weights and starts everything all over from scratch.
