How to include the inputs of the first chain to the second chain in LangChain's SequentialChain?

Question

I receive a list of inputs ['a', 'b'] for the first chain in a SequentialChain, and then I have a second chain that receives as input ['a', 'c'], where c is the output of the first one. I see that SequentialChain passes only the outputs of the first (c) to the second chain. Is there any way to currently do it, without having to implement my own SequentialChain equivalent?

Answer 1

You can pass 'a' to the second chain as the input variables the same you do for your first chain.
