Hi @mkskeller, I am running the ResNet inference example by using the replicated-ring-party protocol. It works well when I compile the network with trunc_pr, split parameter. But when I use split only, it reports:

Using statistical security parameter 40
Trying to run 64-bit computation

replicated-ring-party.x: ./Processor/Processor.hpp:482: void SubProcessor<T>::muls(const std::vector<int>&) [with T = Rep3Share2<64>]: Assertion `reg.size() % 4 == 0' failed.

Aborted (core dumped)

Why did this happen? Thanks.

Sorry, it seems it has been some time since I upgraded the codes. The error is because I am running the old compiled circuit and running it on the latest version of the VM. Thanks.
