[Help Wanted] How to only generate sequential models

[winnylyc]

Hello, sorry for disturbing you.

I am currently testing a machine learning compiler that only accepts sequential models. I would like to know if there is a straightforward method to configure NNSmith in a way that it exclusively generates sequential models. (The sequntial model here means the model can be implemented by only using one torch.nn.Sequential())

Looking foward to your response!
Thanks a lot!

Some similar feature request was proposed in #117 and implemented in #119, which aims to generate models with only one input and one output.

But that is slightly different from your goal to generate a sequential model as this mode can have parallel intermediate nodes.

But you know all models can be sequential or non-sequential per the definition of a "layer". If you regard compound operators as a whole then every multiple operator can be regarded as a compound operator leading to a sequential model. But if you look at the primary operators (such as add) then the so-called sequential models (e.g., those using transformer blocks) are actually non-sequential. i.e., I think this problem first needs to be solved by definition. :D

Thank you for your quick response!
The concept of the "compound operator" you mentioned is indeed relevant to the compiler I am going to test. I am currently further confirming on the extent to which the compound operator can express by the compiler.
