Description

Hi, I'm launching latest SD and latest ControlNet with this arguments to test on CPU only.

--use-cpu all --precision full --no-half --skip-torch-cuda-test

Reactor and SD are all good with CPU but when I activate Control Net it throws following error :

RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:0 and cpu! (when checking argument for argument mat1 in method wrapper_CUDA_addmm)

Am I doing something wrong?

Contributor guide

Research direction
Investigate the ControlNet extension code to find where tensors are explicitly moved to CUDA device, and ensure that when use cpu all is set, all operations fall back to CPU. Look for device assignment in model loading, preprocessing, and inference steps.
