Quickstart

In this example we will explore the basic features of DKubeX. We will start by ingesting a dataset from our workspace, deploying a base LLM model, building a RAG chat application, finetuning the LLM model with a custom dataset, deploying the finetuned LLM model, and building a RAG chat application with the finetuned LLM model. The steps are as follows:

  1. Ingesting Data

  2. Deploying LLMs from Model Catalog

  3. Building your first RAG chat application

  4. Finetuning LLM with custom dataset

  5. Deploying the finetuned LLM

  6. Building a RAG chat application with your finetuned LLM

Prerequisites

  • You must have the current version of DKubeX installed into your system. For detailed instructions regarding installation and logging in to DKubeX, please refer to Installation.

  • For this example, ideally you need a a10 GPU (g5.4xlarge) node attached to your cluster.

    Attention

    In case of a RKE2 setup, please make sure that you have labeled the node as “a10”. Also, in case you are using any other type of GPU node, make sure to use the label for that node which you have put during DKubeX installation process.

  • Make sure you have access and the secret token (only if required) for that particular model which you are going to deploy (in this example, Llama2-7B).

    Note

    In the case the model you want to deploy is not in the DKubeX LLMs registry, you can also deploy LLMs directly from the HuggingFace model hub using the configuration file of that particular model. Make sure you have access to that particular model (in case the model is a private model).

    For instructions on how to deploy the model from HuggingFace repository, please refer to Deploying Base LLMs.

  • Export the following variables to your workspace by running the following commands on your DKubeX Terminal.

    • Replace the <username> part with your DKubeX username.

      export NAMESPACE="<username>"
export HOMEDIR=/home/${NAMESPACE}

  • This example uses the ContractNLI dataset throughout where required. You need to download the dataset on your DKubeX workspace.

    Attention

    Although the ContractsNLI dataset is in accordance with the terms and conditions of the Creative Commons Attribution 4.0 International Public License, it is recommended to go through the terms and conditions of the dataset before using it. You can read the terms and conditions here- https://stanfordnlp.github.io/contract-nli/#download

    • To download the dataset, open the Terminal application from the DKubeX UI and run the following command:

      cd && wget https://stanfordnlp.github.io/contract-nli/resources/contract-nli.zip

    • Unzip the downloaded file using the following command. A folder called contract-nli will be created which will contain the entire dataset. Also at this point, remove the unnecessary files from the dataset folder.

      cd && unzip contract-nli.zip
rm -rf contract-nli/dev.json contract-nli/LICENSE contract-nli/README.md contract-nli/TERMS contract-nli/test.json contract-nli/train.json

Ingesting Data

Note

For detailed information regarding this section, please refer to Data ingestion and creating dataset.

Important

This example uses the BAAI/bge-large-en-v1.5 embeddings model for data ingestion.

Configuring .yaml files for ingestion

You need to provide a few .yaml files to be used during the ingestion process.

  • On the Terminal application in DKubeX UI, run the following commands:

    cd && git clone -b v0.8.1 https://github.com/dkubeio/dkubex-examples.git
cp ${HOMEDIR}/dkubex-examples/rag/ingestion/ingest.yaml ${HOMEDIR}/ingest.yaml && cp ${HOMEDIR}/dkubex-examples/rag/ingestion/custom-pyloaders/custom_sdr.py ${HOMEDIR}/custom_sdr.py

  • You need to provide proper details on the ingest.yaml file. Run vim ${HOMEDIR}/ingest.yaml and make the following changes.

    • On the reader:inputs:loader_args:input_dir: section, provide the absolute path to your dataset folder, i.e. in this case, "/home/<your username>/contract-nli/" (Provide your DKubeX username in place of <your username>).

    • On the reader:pyloader: section, provide the absolute path to the custom_sdr.py file, i.e. in this case, /home/<your username>/custom_sdr.py (Provide your DKubeX username in place of <your username>).

  • You can also modify and customize several other options in the ingest.yaml file according to your needs, including the splitter class, chunk size, embedding model to be used, etc.

Triggering ingestion and creating dataset

  • Open the Terminal application in DKubeX UI.

  • Use the following command to perform data ingestion and create the dataset. A dataset named contracts will be created.

    d3x dataset ingest -d contracts --config ${HOMEDIR}/ingest.yaml

    Note

    • A few documents from the ContractsNLI dataset may show errors during the ingestion process. This is expected behaviour ar those documents’ format are not suitable for ingestion.

    • The time taken for the ingestion process to complete depends on the size of the dataset. The ContractsNLI dataset contains 605 documents and the ingestion process may take around 30 minutes to complete. Please wait patiently for the process to complete.

    • In case the terminal shows a timed-out error, that means the ingestion is still in progress, and you will need to run the command provided on the CLI after the error message to continue to get the ingestion logs.

    • The record of the ingestion and related artifacts are also stored in the MLFlow application on DKubeX UI.

  • To check if the dataset has been created, stored and are ready to use, use the following command:

    d3x dataset list

  • To check the list of documents that has been ingested in the dataset, use the following command:

    d3x dataset show -d contracts

Deploying LLMs from Model Catalog

Note

For detailed information regarding this section, please refer to Deploying LLMs in DKubeX.

Here we will deploy the base Llama2-7B model, which is already pre-registered with DKubeX.

Note

This workflow requires an a10 GPU node. Make sure your cluster is equipped with such. Also, in case you are using any other type of GPU node, make sure to use the label for that node which you have put during DKubeX installation process.

  • To list all LLM models registered with DKubeX, use the following command.

    d3x llms list

  • Export the access token for the Llama2-7B model. Replace the <Huggingface token for Llama2-7B> part with the token for the Llama2-7B model.

    export HF_TOKEN="<Huggingface token for Llama2-7B>"

  • Deploy the base Llama2-7B model using the following command.

    d3x llms deploy --name=llama27bbase --model=meta-llama--Llama-2-7b-chat-hf --token ${HF_TOKEN} --type=a10 --publish

    Note

    In case you are using a EKS setup, please change the value of the flag --type from a10 to g5.4xlarge in the following command. Also, in case you are using any other type of GPU node, make sure to use the label for that node which you have put during DKubeX installation process.

  • You can check the status of the deployment from the Deployments page in DKubeX or by running the following command.

    d3x serve list

  • Wait until the deployment is in running state.

  • What are some common exceptions to confidential information clauses?

Finetuning LLM with custom dataset

Note

For detailed information regarding this section, please refer to Finetuning Open Source LLMs.

  • You will need to use a custom python script for getting the chunks to finetune your LLM model. Run the following command to pull the script to your workspace.

    cd && cp dkubex-examples/rag/finetuning/extract_chunks.py ${HOMEDIR}/extract_chunks.py

  • Generate the chunks using the following command. Replace the <ingestion run ID on MLFlow> part with the run ID of the ingestion run for your dataset on the MLFlow application.

    python3 ${HOMEDIR}/extract_chunks.py --experiment_name chunk-generation --run_id <ingestion run ID on MLFlow> -d ${HOMEDIR}/chunks_for_finetuning/

  • Train the LLM with the chunks using the following command:

    Note

    In case you are using a EKS setup, please change the value of the flag -t from a10 to g5.4xlarge. Also, in case you are using any other type of GPU node, make sure to use the label for that node which you have put during DKubeX installation process.

    Attention

    • The time taken by the finetuning process depends on the size of the dataset. The ContractsNLI dataset contains 605 documents and the finetuning process may take around one hour to complete. Please wait patiently for the process to complete.

    • In case the terminal shows a timed-out error, that means the finetuning is still in progress, and you will need to run the command provided on the CLI after the error message to continue to get the finetuning logs.

  • You will need the absolute path to the finetuned model checkpoint to merge the finetuned model with the base model. Use the following command to get the absolute path to the finetuned model checkpoint:

    echo ${HOME}/ft-output/meta-llama--Llama-2-7b-chat-hf/TorchTrainer_*/TorchTrainer_*/checkpoint*/

    • Export the absolute path to the finetuned model checkpoint to be used during the merge process with the following command. Export the <checkpoint absolute path> part with the absolute path to the finetuned model checkpoint you got in the previous step.

      export CHECKPOINT="<checkpoint absolute path>"

  • Merge the finetuned model checkpoint with the base model to create the final finetuned model using the following command:

    Note

    In case you are using a EKS setup, please change the value of the flag -t from a10 to g5.4xlarge. Also, in case you are using any other type of GPU node, make sure to use the label for that node which you have put during DKubeX installation process.

    d3x fm tune model merge -j llama27bmerge -n meta-llama--Llama-2-7b-chat-hf -cp ${CHECKPOINT} -o ${HOMEDIR}/merge_output -t a10

  • To quantize the finetuned model, use the following command:
