Can't run a 70B Llama 3.1 model on 2 A100 80 gb GPUs.

Hey, so I tired running the 70B llama model on 2gpu/worker but it keeps getting stuck at the same place every time but instead if I switch to the 8B model on 1 gpu/worker with a 48gb GPU, it works easily. The issue is coming with the 70B paramater model on 2 gpus/worker.
