Error in Advanced Manufacturing GT4SD model

I’m using Advanced Manufacturing model in our application. Earlier this model was working fine. Now it is giving the below error. I have attached the error screenshot also.

Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device(‘cpu’) to map your storages to the CPU.
