[Beacon]Get errors when compile logistic model

[deadlywing]

When I follow the instruction in Beacon and want to compile the logistic model with compile_networks.py, I find some error happens in compilation time.

I check the generated logistic.cpp, and find the headers seem to be wrong(lots of auto).

PS: the command I use:

Hi,

Thanks for bringing this to our notice. The Beacon frontend needs to be updated to accommodate the changes to the backend. For now, you can use the network files already committed here or make changes to the file output by the Beacon frontend so that it's consistent with the committed files.

Thanks for replying.
But when I use the committed network files in the repo, I get a core dump error. It seems some bug exists in backward function. However, when I run lenet128, it runs well. The only(I find) difference between two network is that hinet use PoolProp in backward, but the lenet doesn't use this method.
