@xta0 I have used the pytorch 1.3.1 and libtorch 1.3.1. I generated the model in Python, and used torch.jit.trace and torch.jit.save to save the model in a .pt file. I’m able to load the model using torch::jit::load method in the C++ code. However, the same method (torch::jit::load) doesn’t work in the Objective-C version (also 1.3.1).
