# Config for multi-device full finetuning in full_finetune_distributed.py
|
|
# using a Llama3 8B Instruct model
|
|
#
|
|
# This config assumes that you've run the following command before launching
|
|
# this run:
|
|
# tune download meta-llama/Meta-Llama-3-8B-Instruct --output-dir /tmp/Meta-Llama-3-8B-Instruct --hf-token <HF_TOKEN>
|
|
#
|
|
# To launch on 4 devices, run the following command from root:
|
|
# tune run --nproc_per_node 4 full_finetune_distributed --config llama3/8B_full
|
|
#
|
|
# You can add specific overrides through the command line. For example
|
|
# to override the checkpointer directory while launching training
|
|
# you can run:
|
|
# tune run --nproc_per_node 4 full_finetune_distributed --config llama3/8B_full checkpointer.checkpoint_dir=<YOUR_CHECKPOINT_DIR>
|
|
#
|
|
# This config works best when the model is being fine-tuned on 2+ GPUs.
|
|
# Single device full finetuning requires more memory optimizations. It's
|
|
# best to use 8B_full_single_device.yaml for those cases
