jinaai/falcon-40b-code-alpaca-lora

LLM Generation models trained by Jina AI, Finetuner team.

This repo contains the lora weights (8bit) for Falcon-40b fit on the Code Alpaca dataset.

Reproduction

This version of the weights was trained with the following hyperparameters:

Epochs: 2
Batch size: 128
Micro batch size: 4
Learning rate: 3e-4
Lora r: 8
Lora target modules: query_key_value

You can reproduce using this repository:

Make sure you install requirements and finetune using this command using the following command:

python finetune.py \
--base-model tiiuae/falcon-40b --lora-target-modules query_key_value \
--data-path sahil2801/CodeAlpaca-20k --output-dir ./lora-alpaca-code \
--batch-size 128 --micro-batch-size 4 --eval-limit 45 \
--eval-file code_eval.jsonl --wandb-project jerboa --wandb-log-model \
--wandb-watch gradients --num-epochs 2
