Single node on-prem deployment with Ollama on AIPC

This deployment section covers single-node on-prem deployment of the ChatQnA example with OPEA comps to deploy using Ollama. There are several slice-n-dice ways to enable RAG with vectordb and LLM models, but here we will be covering one option of doing it for convenience : we will be showcasing how to build an e2e chatQnA with Redis VectorDB and the llama-3 model, deployed on the client CPU.

Overview

There are several ways to setup a ChatQnA use case. Here in this tutorial, we will walk through how to enable the below list of microservices from OPEA GenAIComps to deploy a single node Ollama megaservice solution.

1. Data Prep

2. Embedding

3. Retriever

4. Reranking

5. LLM with Ollama

The solution is aimed to show how to use Redis vectordb for RAG and the llama-3 model on Intel Client PCs. We will go through how to setup docker container to start microservices and megaservice. The solution will then utilize a sample Nike dataset which is in PDF format. Users can then ask a question about Nike and get a chat-like response by default for up to 1024 tokens. The solution is deployed with a UI. There are 2 modes you can use:

1. Basic UI

2. Conversational UI

Conversational UI is optional, but a feature supported in this example if you are interested to use.

Prerequisites

First step is to clone the GenAIExamples and GenAIComps. GenAIComps are fundamental necessary components used to build examples you find in GenAIExamples and deploy them as microservices.

mkdir ~/OPEA -p
cd ~/OPEA
git clone https://github.com/opea-project/GenAIComps.git
git clone https://github.com/opea-project/GenAIExamples.git

Checkout the release tag

cd ~/OPEA/GenAIComps
git checkout tags/v1.0

Setup your HuggingFace account and generate user access token.

Setup the HuggingFace token

export HUGGINGFACEHUB_API_TOKEN="Your_Huggingface_API_Token"

The example requires you to set the host_ip to deploy the microservices on endpoint enabled with ports. Set the host_ip env variable

export host_ip=$(hostname -I | awk '{print $1}')

Make sure to setup Proxies if you are behind a firewall

export no_proxy=${your_no_proxy},$host_ip
export http_proxy=${your_http_proxy}
export https_proxy=${your_http_proxy}

The examples utilize model weights from Ollama and langchain.

Set Up Ollama LLM Service

We use Ollama as our LLM service for AIPC.

Please follow the instructions to set up Ollama on your PC. This will set the entrypoint needed for the Ollama to suit the ChatQnA examples.

Install Ollama Service

Install Ollama service with one command:

curl -fsSL https://ollama.com/install.sh | sh

Set Ollama Service Configuration

Ollama Service Configuration file is /etc/systemd/system/ollama.service. Edit the file to set OLLAMA_HOST environment. Replace <host_ip> with your host IPV4 (please use external public IP). For example the host_ip is 10.132.x.y, then `Environment=”OLLAMA_HOST=10.132.x.y:11434”’.

Environment="OLLAMA_HOST=host_ip:11434"

Set https_proxy environment for Ollama

If your system access network through proxy, add https_proxy in Ollama Service Configuration file

Environment="https_proxy=Your_HTTPS_Proxy"

Restart Ollama services

$ sudo systemctl daemon-reload
$ sudo systemctl restart ollama.service

Check the service started

netstat -tuln | grep  11434

The output are:

tcp        0      0 10.132.x.y:11434      0.0.0.0:*               LISTEN

Pull Ollama LLM model

Run the command to download LLM models. The <host_ip> is the one set in Ollama Service Configuration

export host_ip=<host_ip>
export OLLAMA_HOST=http://${host_ip}:11434
ollama pull llama3.2

After downloaded the models, you can list the models by ollama list.

The output should be similar to the following:

NAME            ID                SIZE      MODIFIED
llama3.2:latest   a80c4f17acd5    2.0 GB    2 minutes ago

Consume Ollama LLM Service

Access ollama service to verify that the ollama is functioning correctly.

curl http://${host_ip}:11434/api/generate -d '{"model": "llama3.2", "prompt":"What is Deep Learning?"}'

The outputs are similar to these:

{"model":"llama3.2","created_at":"2024-10-12T12:55:28.098813868Z","response":"Deep","done":false}
{"model":"llama3.2","created_at":"2024-10-12T12:55:28.124514468Z","response":" learning","done":false}

Prepare (Building / Pulling) Docker images

This step will involve building/pulling ( maybe in future) relevant docker images with step-by-step process along with sanity check in the end. For ChatQnA, the following docker images will be needed: embedding, retriever, rerank, LLM and dataprep. Additionally, you will need to build docker images for ChatQnA megaservice, and UI (conversational React UI is optional). In total, there are 8 required and an optional docker images.

The docker images needed to setup the example needs to be build local, however the images will be pushed to docker hub soon by Intel.

Build/Pull Microservice images

From within the GenAIComps folder

Build Dataprep Image

cd ~/OPEA/GenAIComps
docker build --no-cache -t opea/dataprep-redis:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f comps/dataprep/redis/langchain/Dockerfile .

Build Embedding Image

docker build --no-cache -t opea/embedding-tei:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f comps/embeddings/tei/langchain/Dockerfile .

Build Retriever Image

 docker build --no-cache -t opea/retriever-redis:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f comps/retrievers/redis/langchain/Dockerfile .

Build Rerank Image

docker build --no-cache -t opea/reranking-tei:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f comps/reranks/tei/Dockerfile .

Build LLM Image

Ollama

Next, we’ll build the Ollama microservice docker. This will set the entry point needed for Ollama to suit the ChatQnA examples

docker build --no-cache -t opea/llm-ollama:latest --build-arg https_proxy=$https_proxy \
   --build-arg http_proxy=$http_proxy -f comps/llms/text-generation/ollama/langchain/Dockerfile .

Build Mega Service images

The Megaservice is a pipeline that channels data through different microservices, each performing varied tasks. We define the different microservices and the flow of data between them in the chatqna.py file, say in this example the output of embedding microservice will be the input of retrieval microservice which will in turn passes data to the reranking microservice and so on. You can also add newer or remove some microservices and customize the megaservice to suit the needs.

Build the megaservice image for this use case

cd ~/OPEA/GenAIExamples/ChatQnA
git checkout tags/v1.0

docker build --no-cache -t opea/chatqna:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f Dockerfile .

Build Other Service images

Build the UI Image

As mentioned, you can build 2 modes of UI

Basic UI

cd ~/OPEA/GenAIExamples/ChatQnA/ui/
docker build --no-cache -t opea/chatqna-ui:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f ./docker/Dockerfile .

Conversation UI If you want a conversational experience with chatqna megaservice.

cd ~/OPEA/GenAIExamples/ChatQnA/ui/
docker build --no-cache -t opea/chatqna-conversation-ui:latest --build-arg https_proxy=$https_proxy \
  --build-arg http_proxy=$http_proxy -f ./docker/Dockerfile.react .

Sanity Check

Check if you have the below set of docker images, before moving on to the next step:

Ollama

• opea/dataprep-redis:latest

• opea/embedding-tei:latest

• opea/retriever-redis:latest

• opea/reranking-tei:latest

• opea/llm-ollama:latest

Megaservice

export MEGA_SERVICE_HOST_IP=${host_ip}
export BACKEND_SERVICE_ENDPOINT="http://${host_ip}:8888/v1/chatqna"

Deploy the use case

In this tutorial, we will be deploying via docker compose with the provided YAML file. The docker compose instructions should be starting all the above mentioned services as containers.

Ollama

cd GenAIExamples/ChatQnA/docker_compose/intel/cpu/aipc
docker compose -f compose.yaml up -d

Validate microservice

Check Env Variables

Check the start up log by docker compose -f ./compose.yaml logs. The warning messages print out the variables if they are NOT set.

Check the container status

Check if all the containers launched via docker compose has started

For example, the ChatQnA example starts 11 docker (services), check these docker containers are all running, i.e, all the containers STATUS are Up To do a quick sanity check, try docker ps -a to see if all the containers are running

Interacting with ChatQnA deployment

This section will walk you through what are the different ways to interact with the microservices deployed

Dataprep Microservice（Optional）

If you want to add/update the default knowledge base, you can use the following commands. The dataprep microservice extracts the texts from variety of data sources, chunks the data, embeds each chunk using embedding microservice and store the embedded vectors in the redis vector database.

Download pdf file:

wget https://raw.githubusercontent.com/opea-project/GenAIComps/main/comps/retrievers/redis/data/nke-10k-2023.pdf

Local File nke-10k-2023.pdf Upload with dataprep: This command updates a knowledge base by uploading a local file for processing.

curl -X POST "http://${host_ip}:6007/v1/dataprep" \
     -H "Content-Type: multipart/form-data" \
     -F "files=@./nke-10k-2023.pdf"

Alternatively, you can add knowledge base via HTTP Links:

curl -X POST "http://${host_ip}:6007/v1/dataprep" \
     -H "Content-Type: multipart/form-data" \
     -F 'link_list=["https://opea.dev"]'

This command updates a knowledge base by submitting a list of HTTP links for processing.

Also, you are able to get the file list that you uploaded:

curl -X POST "http://${host_ip}:6007/v1/dataprep/get_file" \
     -H "Content-Type: application/json"

To delete the file/link you uploaded you can use the following commands:

Delete link

# The dataprep service will add a .txt postfix for link file

curl -X POST "http://${host_ip}:6007/v1/dataprep/delete_file" \
     -d '{"file_path": "https://opea.dev.txt"}' \
     -H "Content-Type: application/json"

Delete file

curl -X POST "http://${host_ip}:6007/v1/dataprep/delete_file" \
     -d '{"file_path": "nke-10k-2023.pdf"}' \
     -H "Content-Type: application/json"

Delete all uploaded files and links

curl -X POST "http://${host_ip}:6007/v1/dataprep/delete_file" \
     -d '{"file_path": "all"}' \
     -H "Content-Type: application/json"

TEI Embedding Service

The TEI embedding service takes in a string as input, embeds the string into a vector of a specific length determined by the embedding model and returns this embedded vector.

curl ${host_ip}:6006/embed \
    -X POST \
    -d '{"inputs":"What is Deep Learning?"}' \
    -H 'Content-Type: application/json'

In this example the embedding model used is “BAAI/bge-base-en-v1.5”, which has a vector size of 768. So the output of the curl command is a embedded vector of length 768.

Embedding Microservice

The embedding microservice depends on the TEI embedding service. In terms of input parameters, it takes in a string, embeds it into a vector using the TEI embedding service and adds other default parameters that are required for the retrieval microservice and returns it.

curl http://${host_ip}:6000/v1/embeddings\
  -X POST \
  -d '{"text":"hello"}' \
  -H 'Content-Type: application/json'

Retriever Microservice

To consume the retriever microservice, you need to generate a mock embedding vector using Python script. The length of embedding vector is determined by the embedding model. Here we use the model EMBEDDING_MODEL_ID=”BAAI/bge-base-en-v1.5”, which vector size is 768.

Check the vector dimension of your embedding model and set your_embedding dimension equal to it.

export your_embedding=$(python3 -c "import random; embedding = [random.uniform(-1, 1) for _ in range(768)]; print(embedding)")

curl http://${host_ip}:7000/v1/retrieval \
  -X POST \
  -d "{\"text\":\"test\",\"embedding\":${your_embedding}}" \
  -H 'Content-Type: application/json'

The output of the retriever microservice comprises of the a unique id for the request, initial query or the input to the retrieval microservice, a list of top n retrieved documents relevant to the input query, and top_n where n refers to the number of documents to be returned. The output is retrieved text that relevant to the input data:

{"id":"27210945c7c6c054fa7355bdd4cde818","retrieved_docs":[{"id":"0c1dd04b31ab87a5468d65f98e33a9f6","text":"Company: Nike. financial instruments are subject to master netting arrangements that allow for the offset of assets and liabilities in the event of default or early termination of the contract.\nAny amounts of cash collateral received related to these instruments associated with the Company's credit-related contingent features are recorded in Cash and\nequivalents and Accrued liabilities, the latter of which would further offset against the Company's derivative asset balance.

TEI Reranking Service

The TEI Reranking Service reranks the documents returned by the retrieval service. It consumes the query and list of documents and returns the document index based on decreasing order of the similarity score. The document corresponding to the returned index with the highest score is the most relevant document for the input query.

curl http://${host_ip}:8808/rerank \
    -X POST \
    -d '{"query":"What is Deep Learning?", "texts": ["Deep Learning is not...", "Deep learning is..."]}' \
    -H 'Content-Type: application/json'

Output is: [{"index":1,"score":0.9988041},{"index":0,"score":0.022948774}]

Reranking Microservice

The reranking microservice consumes the TEI Reranking service and pads the response with default parameters required for the LLM microservice.

curl http://${host_ip}:8000/v1/reranking\
  -X POST \
  -d '{"initial_query":"What is Deep Learning?", "retrieved_docs": \
     [{"text":"Deep Learning is not..."}, {"text":"Deep learning is..."}]}' \
  -H 'Content-Type: application/json'

The input to the microservice is the initial_query and a list of retrieved documents and it outputs the most relevant document to the initial query along with other default parameter such as the temperature, repetition_penalty, chat_template and so on. We can also get top n documents by setting top_n as one of the input parameters. For example:

curl http://${host_ip}:8000/v1/reranking\
  -X POST \
  -d '{"initial_query":"What is Deep Learning?" ,"top_n":2, "retrieved_docs": \
     [{"text":"Deep Learning is not..."}, {"text":"Deep learning is..."}]}' \

Check docker container log

Check the log of container by:

docker logs <CONTAINER ID> -t

Check the log by docker logs f7a08f9867f9 -t.

Also you can check overall logs with the following command, where the compose.yaml is the mega service docker-compose configuration file.

Ollama

docker compose -f ./docker_compose/intel/cpu/apic/compose.yaml logs

Launch UI

Basic UI

To access the frontend, open the following URL in your browser: http://{host_ip}:5173. By default, the UI runs on port 5173 internally. If you prefer to use a different host port to access the frontend, you can modify the port mapping in the compose.yaml file as shown below:

  chaqna-aipc-ui-server:
    image: opea/chatqna-ui:latest
    ...
    ports:
      - "80:5173"

Conversational UI

To access the Conversational UI (react based) frontend, modify the UI service in the compose.yaml file. Replace chaqna-aipc-ui-server service with the chatqna-aipc-conversation-ui-server service as per the config below:

chaqna-aipc-conversation-ui-server:
  image: opea/chatqna-conversation-ui:latest
  container_name: chatqna-aipc-conversation-ui-server
  environment:
    - APP_BACKEND_SERVICE_ENDPOINT=${BACKEND_SERVICE_ENDPOINT}
    - APP_DATA_PREP_SERVICE_URL=${DATAPREP_SERVICE_ENDPOINT}
  ports:
    - "5174:80"
  depends_on:
    - chaqna-aipc-backend-server
  ipc: host
  restart: always

Once the services are up, open the following URL in your browser: http://{host_ip}:5174. By default, the UI runs on port 80 internally. If you prefer to use a different host port to access the frontend, you can modify the port mapping in the compose.yaml file as shown below:

  chaqna-aipc-conversation-ui-server:
    image: opea/chatqna-conversation-ui:latest
    ...
    ports:
      - "80:80"

Stop the services

Once you are done with the entire pipeline and wish to stop and remove all the containers, use the command below:

Ollama

docker compose -f compose.yaml down
