O-LoRA

• This repo releases our implementation for the O-LoRA model.
• It is built based on the pretrained T5-large model, and finetuned on our data.

Setup

You can install the required libraries by running

pip install -r requirements.txt

You are also required to download the t5-large model from huggingface, put it to the folder named initial_model, and rename the model folder as 't5-large'.

LLaMA2 HF is also supported. You can put your llama2 hf model to the folder named initial_model and rename the model folder as 'llama'.

Training and Evaluation

For t5-large:

You can reproduce our experiments of order 1 & 2 & 3 by simply running

order1:

bash scripts/order_1.sh> logs_and_outputs/order_1/logs/train_and_infer.log 2>&1 &

order2:

bash scripts/order_2.sh> logs_and_outputs/order_2/logs/train_and_infer.log 2>&1 &

order3:

bash scripts/order_3.sh> logs_and_outputs/order_3/logs/train_and_infer.log 2>&1 &

The model you have trained will be saved in logs_and_outputs/order_1(2 or 3)/outputs.

The result of each task will be saved in logs_and_outputs/order_1(2 or 3)/outputs/TASK_NAME/predict_results.json.

You can also check the logs during training and infering in logs_and_outputs/order_1(2 or 3)/logs/train_and_infer.log

For LLaMA2:

order1:

bash scripts_llama/order_1.sh> logs_and_outputs_llama/order_1/logs/train_and_infer.log 2>&1 &

order2:

bash scripts_llama/order_2.sh> logs_and_outputs_llama/order_2/logs/train_and_infer.log 2>&1 &

order3:

bash scripts_llama/order_3.sh> logs_and_outputs_llama/order_3/logs/train_and_infer.log 2>&1 &
