Hi,
Your colab link is private, please allow sharing so that i can look into it.

But by looking at the error it seems there’s some issue with the data generator function.

Can you try yielding a tuple from the function.
instead of yield [[np.array(X1),np.array(X2)],np.array(y)]

try this : yield ([np.array(X1),np.array(X2)],np.array(y))

Thanks
