Libtorch NNPACK

C++
1

hi, I am new to pytorch and torchlib.
I am trying to run a model on torchlib for cpp, the model was written and trained in python pytorch.
I succeeded in reading the model in cpp but when I used the forward method I got the following error:
[W NNPACK.cpp:51] Could not initialize NNPACK! Reason: Unsupported hardware.

I cannot figure out what is the problem here

Some devs said it’s because NNPACK (a component of libtorch and pytorch) requires AVX2 instruction sets to initialize. See Bug report about NNPACK

Are you running on a robot or some thing like that? I am facing the same issue on a robotic dog. It’s suggested to change the board CPU with a stronger one.
