# Remote vLLM Distribution
|
||||
|
||||
The `llamastack/distribution-remote-vllm` distribution consists of the following provider configurations.
|
||||
|
||||
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|
||||
|----------------- |---------------- |---------------- |------------------------------------ |---------------- |---------------- |
|
||||
| **Provider(s)** | remote::vllm | meta-reference | remote::pgvector, remote::chromadb | meta-reference | meta-reference |
|
||||
|
||||
You can use this distribution if you have GPUs and want to run an independent vLLM server container for running inference.
|
||||
|
||||
## Using Docker Compose
|
||||
|
||||
You can use `docker compose` to start a vLLM container and Llama Stack server container together.
|
||||
|
||||
> [!NOTE]
|
||||
> This assumes you have access to GPU to start a vLLM server with access to your GPU.
|
||||
|
||||
```bash
|
||||
$ cd distributions/remote-vllm; docker compose up
|
||||
```
|
||||
|
||||
You will see outputs similar to following ---
|
||||

||||
|
||||
To kill the server
|
||||
```bash
|
||||
docker compose down
|
||||
```
|
||||
|
||||
## Starting vLLM and Llama Stack separately
|
||||
|
||||
You may want to start a vLLM server and connect with Llama Stack manually. There are two ways to start a vLLM server and connect with Llama Stack.
|
||||
|
||||
|
||||
#### Start vLLM server.
|
||||
|
||||
```bash
|
||||
docker run --runtime nvidia --gpus all \
|
||||
-v ~/.cache/huggingface:/root/.cache/huggingface \
|
||||
--env "HUGGING_FACE_HUB_TOKEN=<secret>" \
|
||||
-p 8000:8000 \
|
||||
--ipc=host \
|
||||
vllm/vllm-openai:latest \
|
||||
--model meta-llama/Llama-3.1-8B-Instruct
|
||||
```
|
||||
|
||||
Please check the [vLLM Documentation](https://docs.vllm.ai/en/v0.5.5/serving/deploying_with_docker.html) for more details.
|
||||
|
||||
|
||||
#### Start Llama Stack server pointing to your vLLM server
|
||||
|
||||
|
||||
We have provided a template `run.yaml` file in the `distributions/remote-vllm` directory. Please make sure to modify the `inference.provider_id` to point to your vLLM server endpoint. As an example, if your vLLM server is running on `http://127.0.0.1:8000`, your `run.yaml` file should look like the following:
|
||||
```yaml
|
||||
inference:
|
||||
- provider_id: vllm0
|
||||
provider_type: remote::vllm
|
||||
config:
|
||||
url: http://127.0.0.1:8000
|
||||
```
|
||||
|
||||
**Via Conda**
|
||||
|
||||
If you are using Conda, you can build and run the Llama Stack server with the following commands:
|
||||
```bash
|
||||
cd distributions/remote-vllm
|
||||
llama stack build --template remote_vllm --image-type conda
|
||||
llama stack run run.yaml
|
||||
```
|
||||
|
||||
**Via Docker**
|
||||
|
||||
You can use the Llama Stack Docker image to start the server with the following command:
|
||||
```bash
|
||||
docker run --network host -it -p 5000:5000 \
|
||||
-v ~/.llama:/root/.llama \
|
||||
-v ./gpu/run.yaml:/root/llamastack-run-remote-vllm.yaml \

"4. **Diet**: Llamas are herbivores and feed on a variety of plants, including grasses, leaves, and shrubs. They are known for their ability to digest plant material that other animals cannot.\n",
|
||||
"5. **Behavior**: Llamas are social animals and live in herds. They are known for their intelligence, curiosity, and strong sense of self-preservation.\n",
|
||||
"6. **Purpose**: Llamas have been domesticated for thousands of years and have been used for a variety of purposes, including:\n",
|
||||
"\t* **Pack animals**: Llamas are often used as pack animals, carrying goods and supplies over long distances.\n",
|
||||
"\t* **Fiber production**: Llama wool is highly valued for its softness, warmth, and durability.\n",
|
||||
"\t* **Meat**: Llama meat is consumed in some parts of the world, particularly in South America.\n",

"#### Key Highlights:\n",
|

"- **`WeatherTool` Class**: A custom tool that processes weather information requests, supporting location and optional date parameters.\n",
|
||||
"- **Agent Creation**: The `create_weather_agent` function sets up an agent equipped with the `WeatherTool`, allowing for weather queries in natural language.\n",
|
||||
"- **Simulation of API Call**: The `run_impl` method simulates fetching weather data. This method can be replaced with an actual API integration for real-world usage.\n",
|
||||
"- **Interactive Example**: The `weather_example` function shows how to use the agent to handle user queries regarding the weather, providing step-by-step responses."

Firstly, the parameters which control\\nwhich linear layers LoRA should be applied to in the model:\\n\\n* ``lora_attn_modules: List[str]`` accepts a list of strings specifying which layers of the model to apply\\n LoRA to:\\n\\n * ``q_proj`` applies LoRA to the query projection layer.\\n * ``k_proj`` applies LoRA to the key projection layer.\\n * ``v_proj`` applies LoRA to the value projection layer.\\n * ``output_proj`` applies LoRA to the attention output projection layer.\\n\\n Whilst adding more layers to be fine-tuned may improve model accuracy,\\n this will come at the cost of increased memory usage and reduced training speed.\\n\\n* ``apply_lora_to_mlp: Bool`` applies LoRA to the MLP in each transformer layer.\\n* ``apply_lora_to_output: Bool`` applies LoRA to the model's final output projection.\\n This is usually a projection to vocabulary space (e.g. in language models),\", document_id='url-doc-0', token_count=512)\n",

# Ollama Quickstart Guide
|
||||
|
||||
This guide will walk you through setting up an end-to-end workflow with Llama Stack with ollama, enabling you to perform text generation using the `Llama3.2-1B-Instruct` model. Follow these steps to get started quickly.
|
||||
|
||||
If you're looking for more specific topics like tool calling or agent setup, we have a [Zero to Hero Guide](#next-steps) that covers everything from Tool Calling to Agents in detail. Feel free to skip to the end to explore the advanced topics you're interested in.
|
||||
|
||||
> If you'd prefer not to set up a local server, explore our notebook on [tool calling with the Together API](Tool_Calling101_Using_Together's_Llama_Stack_Server.ipynb). This guide will show you how to leverage Together.ai's Llama Stack Server API, allowing you to get started with Llama Stack without the need for a locally built and running server.

## Setup ollama
|
||||
|
||||
1. **Download Ollama App**:
|
||||
- Go to [https://ollama.com/download](https://ollama.com/download).
|
||||
- Download and unzip `Ollama-darwin.zip`.
|
||||
- Run the `Ollama` application.
|
||||
|
||||
2. **Download the Ollama CLI**:
|
||||
- Ensure you have the `ollama` command line tool by downloading and installing it from the same website.
|
||||
|
||||
3. **Verify Installation**:
|
||||
- Open the terminal and run:
|
||||
```bash
|
||||
ollama run llama3.2:1b
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Install Dependencies and Set Up Environment
|
||||
|
||||
1. **Create a Conda Environment**:
|
||||
- Create a new Conda environment with Python 3.11:
|
||||
```bash
|
||||
conda create -n hack python=3.11
|
||||
```
|
||||
- Activate the environment:
|
||||
```bash
|
||||
conda activate hack
|
||||
```
|
||||
|
||||
2. **Install ChromaDB**:
|
||||
- Install `chromadb` using `pip`:
|
||||
```bash
|
||||
pip install chromadb
|
||||
```
|
||||
|
||||
3. **Run ChromaDB**:
|
||||
- Start the ChromaDB server:
|
||||
```bash
|
||||
chroma run --host localhost --port 8000 --path ./my_chroma_data
|
||||
```
|
||||
|
||||
4. **Install Llama Stack**:
|
||||
- Open a new terminal and install `llama-stack`:
|
||||
```bash
|
||||
conda activate hack
|
||||
pip install llama-stack
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Build, Configure, and Run Llama Stack
|
||||
|
||||
1. **Build the Llama Stack**:
|
||||
- Build the Llama Stack using the `ollama` template:
|
||||
```bash
|
||||
llama stack build --template ollama --image-type conda
|
||||
```
|
||||
|
||||
2. **Edit Configuration**:
|
||||
- Modify the `ollama-run.yaml` file located at `/Users/yourusername/.llama/distributions/llamastack-ollama/ollama-run.yaml`:
|
||||
- Change the `chromadb` port to `8000`.
|
||||
- Remove the `pgvector` section if present.
|
||||
|
||||
3. **Run the Llama Stack**:
|
||||
- Run the stack with the configured YAML file:
|
||||
```bash
|
||||
llama stack run /path/to/your/distro/llamastack-ollama/ollama-run.yaml --port 5050
|
||||
```
|
||||
|
||||
The server will start and listen on `http://localhost:5050`.
|
||||
|
||||
---
|
||||
|
||||
## Testing with `curl`
|
||||
|
||||
After setting up the server, open a new terminal window and verify it's working by sending a `POST` request using `curl`:
|
||||
|
||||
```bash
|
||||
curl http://localhost:5050/inference/chat_completion \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "llama3.2:1b",
|
||||
"messages": [
|
||||
{"role": "system", "content": "You are a helpful assistant."},
|
||||
{"role": "user", "content": "Write me a 2-sentence poem about the moon"}
|
||||
],
|
||||
"sampling_params": {"temperature": 0.7, "seed": 42, "max_tokens": 512}
|
||||
}'
|
||||
```
|
||||
|
||||
**Expected Output:**
|
||||
```json
|
||||
{
|
||||
"completion_message": {
|
||||
"role": "assistant",
|
||||
"content": "The moon glows softly in the midnight sky,\nA beacon of wonder, as it catches the eye.",
|
||||
"stop_reason": "out_of_tokens",
|
||||
"tool_calls": []
|
||||
},
|
||||
"logprobs": null
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing with Python
|
||||
|
||||
You can also interact with the Llama Stack server using a simple Python script. Below is an example:
|
||||
|
||||
### 1. Active Conda Environment and Install Required Python Packages
|
||||
The `llama-stack-client` library offers a robust and efficient python methods for interacting with the Llama Stack server.
|
||||
|
||||
```bash
|
||||
conda activate your-llama-stack-conda-env
|
||||
pip install llama-stack-client
|
||||
```
|
||||
|
||||
### 2. Create Python Script (`test_llama_stack.py`)
|
||||
```bash
|
||||
touch test_llama_stack.py
|
||||
```
|
||||
|
||||
### 3. Create a Chat Completion Request in Python
|
||||
|
||||
```python
|
||||
from llama_stack_client import LlamaStackClient
|
||||
|
||||
# Initialize the client
|
||||
client = LlamaStackClient(base_url="http://localhost:5050")
|
||||
|
||||
# Create a chat completion request
|
||||
response = client.inference.chat_completion(
|
||||
messages=[
|
||||
{"role": "system", "content": "You are a helpful assistant."},
|
||||
{"role": "user", "content": "Write a two-sentence poem about llama."}
|
||||
],
|
||||
model="llama3.2:1b",
|
||||
)
|
||||
|
||||
# Print the response
|
||||
print(response.completion_message.content)
|
||||
```
|
||||
|
||||
### 4. Run the Python Script
|
||||
|
||||
```bash
|
||||
python test_llama_stack.py
|
||||
```
|
||||
|
||||
**Expected Output:**
|
||||
```
|
||||
The moon glows softly in the midnight sky,
|
||||
A beacon of wonder, as it catches the eye.
|
||||
```
|
||||
|
||||
With these steps, you should have a functional Llama Stack setup capable of generating text using the specified model. For more detailed information and advanced configurations, refer to some of our documentation below.
|
||||
|
||||
This command initializes the model to interact with your local Llama Stack instance.
