Weight sharing missing?

Hi,

Thanks for the code. I notice that in the original code, the weights of C are shared, as in https://github.com/facebook/MemNN/blob/946c4784b59dcf053bbbbb9637d6814bc152c276/MemN2N-lang-model/model.lua#L67-L74

However, I cannot find the weight sharing part in this code. Did I miss something? Thank you.

Start with the linked MemN2N-lang-model/model.lua lines 67-74, then trace the TensorFlow implementation of the C weights. Confirm whether weight sharing is present; done means the discrepancy is clearly explained or the missing behavior is precisely identified.
