11B_full_single_device.yaml

# Config for single device full finetuning in full_finetune_single_device.py
# using a Llama3.2 11B Vision Instruct model
#
# This config assumes that you've run the following command before launching:
#   tune download meta-llama/Llama-3.2-11B-Vision-Instruct --output-dir /tmp/Llama-3.2-11B-Vision-Instruct
#
# The default config uses an optimizer from bitsandbytes. If you do not have it installed,
# you can install it with:
#   pip install bitsandbytes
#
# To launch on a single device, run the following command from root:
#   tune run full_finetune_single_device --config llama3_2_vision/11B_full_single_device
#
# You can add specific overrides through the command line. For example
# to override the checkpointer directory while launching training:
#   tune run full_finetune_single_device --config llama3_2_vision/11B_full_single_device checkpointer.checkpoint_dir=<YOUR_CHECKPOINT_DIR>
#
# This config works only for training on single device.
