fix: torch.load requires weights_only 

See: https://pytorch.org/blog/pytorch2-6/
Also in this release as an important security improvement measure we have changed the default value for weights_only parameter of torch.load. This is a backward compatibility-breaking change, please see this forum post for more details.
