"RuntimeError: Distributed package doesn't have NCCL built in" trying to run example chat completion locally

[pentney]

Trying to run on my GPU-less laptop, and I just want to try running inference locally with

PYTHONPATH=$(git rev-parse --show-toplevel) torchrun llama_models/scripts/example_chat_completion.py $CHECKPOINT_DIR
I'm getting the error:

         File "/home/bill/.venv/lib/python3.11/site-packages/torch/distributed/distributed_c10d.py", line 1750, in _new_process_group_helper
      raise RuntimeError("Distributed package doesn't have NCCL built in")       ^^^
 ^^^    ^raise RuntimeError("Distributed package doesn't have NCCL built in")^ 

Is there a configuration for the script that will run without NCCL? Thanks
