Llama2 is an open-source large language model (LLM) developed by Meta. It’s designed to rival other prominent language models and is used for a variety of tasks, including natural language processing (NLP) and code completion. To use Llama2, you need to install it using Ollama, an open-source LLM package management tool
For installing llama 3.1 you can follow below mentioned article:
Requirements
Before we begin, understand that running the Ollama Chatbot UI on Linux requires some heavy hardware. For best results, have a modern Nvidia GPU with some GPU memory to work with. Alternatively, if you do not have an Nvidia GPU, have a multi-core Intel or AMD CPU to run it in CPU mode
Installation Steps
Step 1: Install Ollama
The first step is to install Ollama. Open up a terminal window on your Linux desktop and enter the following command
curl https://ollama.ai/install.sh | sh
This command will download and install Ollama on your system. Once the installation is complete, you can check if Ollama is installed correctly by running the ollama command in the terminal.
Step 2: Download the Llama2 Model
Once Ollama is installed, you can download the Llama2 model. Run the following command in your terminal
# download the 7B model (3.8 GB)
ollama pull llama2
# or the 13B model (7.3 GB)
ollama pull llama2:13b
You can download any one from the above
Step 3: Run Llama2 and Interact with It
After downloading the Llama2 model, you can run the model and chat with it by using the following command
ollama run llama2
Potential Problems and Solutions
Ollama Command Not Working: If nothing happens after running ollama in the terminal, re-run the script and re-install it.
Running Ollama in the Background: Ollama needs to be running in the background so that you can interact with it to pull down various large language models, and to interact with them. You can use a Python tool to run Ollama’s server in the background on Linux and end it when the user asks.

Conclusion
Llama2 is an advanced and powerful large language model that has been created by Meta, the parent company of Facebook. As an open-source project, Llama2 is freely available to developers and researchers who want to leverage its capabilities for their own projects. This LLM is built to compete with other leading language models in the industry, offering users a high-quality tool for a range of applications.
One of the key uses of Llama2 is in the field of natural language processing (NLP), where it can be employed to understand, interpret, and generate human-like text. This makes it an invaluable resource for creating chatbots, virtual assistants, and other AI-driven communication tools. Additionally, Llama2 is adept at code completion tasks, helping developers to write code more efficiently by predicting and suggesting the next lines of code based on the context.
To access the features of Llama2, users must first install the model. This is where Ollama comes into play. Ollama is an open-source package management tool specifically designed for managing and installing large language models like Llama2. It simplifies the process of setting up Llama2 on a user’s system, ensuring that all necessary dependencies and configurations are correctly handled. With Ollama, users can quickly get Llama2 up and running, allowing them to focus on developing and deploying their NLP or code completion applications with ease.
Overall, Llama2 represents a significant contribution to the open-source community, providing a robust and versatile tool that can enhance a wide array of language-related tasks. Its development by Meta underscores the importance of large language models in the evolving landscape of artificial intelligence, and its availability as an open-source project democratizes access to cutting-edge technology.
