Nyuntam Adapt

A robust adaptation module that effortlessly fine-tunes and performs transfer learning on a diverse range of deep learning tasks and models. With ADAPT, users can adapt large and even medium-sized vision and language models seamlessly, enabling the creation of custom models with just a few clicks. This module incorporates state-of-the-art adaptation methods such as (Q)-LoRA, SSF, etc., allowing users to strike the optimal balance across various model metrics, including parameter count and training throughput.

Installation

Installation can be performed either via installing requirements in a virtual environment or by utilizing our docker images. To quickly run Adapt for experimentation and usage, utilize Nyun CLI to get Adapt running in a few clicks. For contributing to Adapt build docker containers from the available docker image or create a virtual enviroment from the provided requirements.txt.

Nyunzero CLI

The recommended method to install and use nyuntam-adapt is via the nyunzero-cli. Further details can be found here : NyunZero CLI

Git + Docker

Nyuntam-Adapt can also be used by cloning the repository and pulling hhe required docker.

  1. Git Clone : First, clone the repository to your local machine:

    $ git clone --recursive https://github.com/nyunAI/nyuntam_adapt.git
$ cd nyuntam_adapt

  2. Docker Pull: Next, pull the docker container and run it :

    $ docker pull nyunadmin/nyunzero_adapt:v0.1

$ docker run -it -d --gpus all -v /dev/shm:/dev/shm -v $(pwd):/workspace --name {CONTAINER_NAME} --network=host nyunadmin/nyunzero_adapt:v0.1 bash

NOTE: nvidia-container-toolkit is expected to be installed before the execution of this

  1. Docker run: Next, start the docker.

    $ docker exec -it {CONTAINER_NAME} /bin/bash

Now you are all set to finetune models using nyuntam adapt.

Git + virtual environment

Nyuntam Aadpt can also be used by cloning the repository and setting up a virtual environment.

  1. Git Clone : First, clone the repository to your local machine:

    $ git clone --recursive https://github.com/nyunAI/nyuntam_adapt.git
$ cd nyuntam_adapt

  2. Create a virtual environment using Venv

    python3 -m venv {ENVIRONMENT_NAME}
source {ENVIRONMENT_NAME}/bin/activate

  3. Pip install requirements

    pip install -r requirements.txt

Usage

Setting up the YAML files

If the dataset and models weights exist online (huggingface hub) then the experiments can be started easily. Adapt requires a yaml file for all the required hyperparameters to finetune a model. The yaml files for all the tasks are here : YAML FILES

The major hyperparameters are metioned below :

  • Dataset
DATASET: teknium/openhermes
DATASET_TYPE: LLM - Openhermes
DATASET_CONFIG : {}
CUSTOM_DATASET_PATH :
  1. "DATASET" refers to the name of the dataset as can be found on the hugginface hub. eg - 'mlabonne/guanaco-llama2-1k'.
  2. The "DATASET_TYPE" refers to the user given name for the dataset.
  3. Some datasets like opus-books have subsets like - "en-fr". These are used while downloading the dataset and can be mentioned in "DATASET_CONFIG".
  4. "CUSTOM_DATASET_PATH" refers to the dataset path is user has a custom dataset that is not on huggingface hub.

Further information about using custom datasets can be found here

  • Model
Library: Huggingface
MODEL: Llama-3
MODEL_PATH: meta-llama/Meta-Llama-3-70B
LOCAL_MODEL_PATH :
  1. "Library" is self explanatory and refers to the library which is used for the model. for all the language tasks, Adapt supports Huggingface and Timm and Huggingface are supported for vision tasks.
  2. "MODEL" refers to the user given name of the model and can be chosen by the user. this DOES NOT refer to the model details.
  3. "MODEL_PATH" refers to the huggingface model id and needs to be the same as that in the HF hub.
  4. "LOCAL_MODEL_PATH" refers to the path of the model weights if the user has custom model weights.

Further information about using custom model weights can be found here

  • Layers to tune
LAST_LAYER_TUNING : False
FULL_FINE_TUNING :  False
  1. "LAST_LAYER_TUNING" should be set to True when only the last layer is to be fine tuned of the model. When PEFT methods are used, LAST_LAYER_TUNING ensures that the layers that are to be finetuned are the PEFT modules and the last layer of the network.
  2. "FULL_FINE_TUNING" should be set to True when the all the layers of the model weights are to be finetuned. This utilises lot of computational resources.
  • PEFT arguments
PEFT_METHOD : 'LoRA'
r : 2
alpha : 16
dropout : 0.1
peft_type : 'LoRA'
target_modules :

  1. "distributed_type" should be set to FSDP to ensure that model being trained on multiple GPUs (if they are available)
  2. "fsdp_sharding_strategy" refers to the sharding strategy to be used while training the model. If "NO_SHARD" is selected, then it behaves like [Distributed Data Parallel](https://pytorch.org/tutorials/intermediate/ddp_tutorial.html)
