Getting Started with OpenLLM

Step 1. Install OpenLLM

Before you can harness the power of OpenLLM, you'll need to get it up and running on your system. The installation process is straightforward and can be completed in just a few steps. OpenLLM is available on PyPI, which means you can install it using Python's package manager, pip.

pip install openllm

This single command will download and install OpenLLM, along with any required dependencies. Make sure you have Python 3.8 or higher installed on your system for a smooth installation process.

• Python Version: OpenLLM requires Python 3.8 or higher. You can check your Python version by running python --version in your terminal.

• Package Dependencies: The pip install openllm command will also install any required package dependencies automatically, so you don't have to worry about missing out on any crucial components.

• Virtual Environment: It's a good practice to install Python packages in a virtual environment to avoid any conflicts with system-wide packages. You can create a virtual environment using python -m venv myenv and activate it before running the pip command.

By following these detailed steps, you'll have OpenLLM installed and ready for action in no time.

Step 2. Running Your First OpenLLM App

Once you've installed OpenLLM, you're all set to run your first OpenLLM app. Starting an LLM server locally is as simple as executing a single command. For instance, if you want to start a Dolly v2 model, you can do so with the following command:

openllm start dolly-v2

This command will initialize the Dolly v2 model and start the OpenLLM server, making it accessible for other applications or services to interact with.

• Port Configuration: By default, the OpenLLM server runs on port 5000. However, you can specify a different port using the --port flag, like so: openllm start dolly-v2 --port 6000.

• Logging: OpenLLM provides detailed logs that can help you debug or optimize your models. You can specify the level of logging detail with the --log-level flag.

• Resource Allocation: If you're running multiple models, OpenLLM allows you to allocate specific resources to each one, ensuring optimal performance.

Running your first OpenLLM app is that simple! You now have a working large language model running locally, ready to be integrated into your projects or deployed in a production environment.

How to Deploy OpenLLM with Docker and Kubernetes

Step 1. Setting Up Your Environment for Open LLM

Before you can deploy your large language models with OpenLLM, it's essential to prepare your environment. This involves several steps, including installing NVIDIA GPU drivers, CUDA libraries, and setting up Kubernetes with GPU support. Each of these components plays a crucial role in enabling GPU acceleration, which is vital for maximizing the performance of your large language models.

Step 1.1. Installing NVIDIA GPU Drivers

Firstly, you'll need to install the NVIDIA GPU drivers to enable GPU support on your machine. You can do this with the following command:

sudo apt-get update && sudo apt-get install -y nvidia-driver-460

After installation, reboot your machine to activate the drivers.

Step 1.2. Installing CUDA Libraries

Next, you'll need to install the CUDA toolkit, which provides the development environment for GPU-accelerated applications. Use the following command to install CUDA 11.0:

sudo apt-get update && sudo apt-get install -y cuda-11-0

After installing, add CUDA to your PATH:

echo 'export PATH=/usr/local/cuda-11.0/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Step 1.3. Installing Kubernetes and Minikube

To set up a local Kubernetes cluster, you can use Minikube. Install it with the following command:

sudo apt-get update && sudo apt-get install -y minikube

Once Minikube is installed, start it with GPU support:

minikube start --driver=nvidia

This will start a local Kubernetes cluster with NVIDIA GPU support.

Step 1.4. Enabling Kubernetes GPU Support

Finally, to enable GPU support in your Kubernetes cluster, you'll need to deploy the NVIDIA device plugin. Use the following command to do so:

kubectl create -f https://raw.githubusercontent.com/NVIDIA/k8s-device-plugin/v0.9.0/nvidia-device-plugin.yml

This will deploy the NVIDIA device plugin to your cluster, enabling GPU support for your pods.

By following these detailed steps, you'll set up an environment that's ready for deploying large language models with OpenLLM, fully optimized for GPU acceleration.

Step 2. Containerizing and Loading Models with OpenLLM

OpenLLM allows you to containerize your large language models and load them into a Docker container. This is particularly useful for ensuring a consistent runtime environment across different deployments. To containerize your model, you can use the following command:

openllm build dolly-v2 --model-id databricks/dolly-v2-3b

This will package your LLM model, OpenLLM dependencies, and other relevant libraries within a Docker container. To generate an OCI-compatible Docker image, run:

bentoml containerize <name:version> -t dolly-v2-3b:latest --opt progress=plain

Step 3. Deploying on Kubernetes

Kubernetes offers features like Horizontal Pod Autoscaling (HPA) that can help efficiently scale your model for production use. You can set up communication protocols within pods to manage model input and output, either through RESTful APIs or gRPC-based communication. OpenLLM has a gRPC server running by default on port 3000. A sample Kubernetes deployment file could look like this:

apiVersion: apps/v1
kind: Deployment
metadata:
 name: dolly-v2-deployment
spec:
 replicas: 3
 selector:
   matchLabels:
     app: dolly-v2
 template:
   metadata:
     labels:
       app: dolly-v2
   spec:
     containers:
     - name: dolly-v2
       image: dolly-v2-3b:latest
       imagePullPolicy: Never
       ports:
       - containerPort: 3000

For autoscaling, you can configure HPAs to automatically adjust the number of pods based on CPU or custom metrics. This ensures optimal resource utilization.

apiVersion: autoscaling/v1
kind: HorizontalPodAutoscaler
metadata:
 name: dolly-v2-hpa
spec:
 scaleTargetRef:
   apiVersion: apps/v1
   kind: Deployment
   name: dolly-v2-deployment
 minReplicas: 1
 maxReplicas: 10
 targetCPUUtilizationPercentage: 60

By leveraging Docker and Kubernetes, OpenLLM allows for a seamless and scalable deployment process, ensuring that your large language models are both performant and cost-effective.
