Want to build AI Apps powered by any AI model? No worries, simply create a new chatbot, or workflow, and select your desired AI model as the option. Say, you want to try out the Llama 13B, Llama 70B models right now, simply use Anakin AI and build your app with one click:
Llama.cpp is a library developed by Georgi Gerganov, designed to run Large Language Models (LLMs) efficiently on CPUs, especially beneficial for those without access to GPUs. It offers high-speed inference for a variety of LLMs and can be integrated with Python through the llama-cpp-python package, allowing users to leverage Python's extensive libraries in their projects.
Installation: The first step is to install the llama-cpp-python package, which provides Python bindings for the llama.cpp library, making it easier to use in Python environments. You can install it using pip:
pip install llama-cpp-python
For more detailed installation instructions, you can refer to the llama-cpp-python documentation.
Downloading and Loading the LLM: You need to download the model in GGML format from a source like Hugging Face. Ensure the model has been quantized to reduce memory requirements without significantly impacting performance. Here's an example code snippet for downloading and loading a model:
import os
import urllib.request
from llama_cpp import Llama
def download_file(file_link, filename):
if not os.path.isfile(filename):
urllib.request.urlretrieve(file_link, filename)
print("File downloaded successfully.")
else:
print("File already exists.")
ggml_model_path = "MODEL_LINK_HERE"
filename = "MODEL_FILENAME_HERE"
download_file(ggml_model_path, filename)
llm = Llama(model_path=filename, n_ctx=512, n_batch=126)
Replace "MODEL_LINK_HERE" and "MODEL_FILENAME_HERE" with the actual link and filename of your GGML model.
Generating Text: Once the model is loaded, you can generate text by passing a prompt to the model. Here’s a simple function to generate text:
def generate_text(prompt, max_tokens=256, temperature=0.1, top_p=0.5, echo=False, stop=["#"]):
output = llm(prompt, max_tokens=max_tokens, temperature=temperature, top_p=top_p, echo=echo, stop=stop)
return output["choices"][0]["text"].strip()
This function allows customization of the generation process, including setting the maximum number of tokens, temperature for randomness, and stopping conditions.
Ollama stands out for its simplicity, cost-effectiveness, privacy, and versatility, making it an attractive alternative to cloud-based LLM solutions. It eliminates latency and data transfer issues associated with cloud models and allows for extensive customization.
Step 1. Visit Ollama website and download the ollama dmg package.
Step 2. Install one of the available llama models that ollama currently supports. Simply run this command in your Mac Terminal:
ollama run llama2If you want to test out the pre-trained version of llama2 without chat fine-tuning, use this command: ollama run llama2:text
There are many version of Llama 2 that ollama supports out-of-the-box. Depends on the parameters and system memory, select one of your desired option:
Commonly speaking, for users with a modest local environment, it is suggested to run the 7B-Chat_Q4_K_M model.
ollama run llama2:7b-chat-q4_K_MInstall Docker: First, ensure Docker is installed on your system. If not, download and install it from the official Docker website.
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
Pull Ollama Docker Image: With Docker set up, pull the Ollama image by running the following command in your terminal:
docker pull ollama/ollama
Run Ollama: To start Ollama, execute:
docker run -it ollama/ollama
This command launches Ollama, and you can begin interacting with the models.
ollama list to view available models.ollama run <model_name>.ollama stop <model_name> will do the trick.Ollama's cross-platform support extends beyond Linux, catering to Windows and macOS users as well, thus broadening its appeal.
ollama.exe run.For tasks demanding extensive computation, Ollama harnesses GPU acceleration to enhance performance, supporting both NVIDIA and AMD GPUs. Ensure you have the right drivers installed for your GPU, and activate GPU support by adding a --gpu flag to your command:
ollama run --gpu <model_name>
This command enables GPU acceleration, significantly boosting model inference speeds.
Ollama's compatibility with Python amplifies its utility in data science and machine learning projects. After installing the Ollama Python package (pip install ollama), you can easily incorporate Ollama models into your Python scripts, enabling direct interactions and inferences within your codebase.
Incorporating the provided instructions for running Llama 2 on Windows into your article, here is how you could structure and detail this section:
For those in the Windows ecosystem, setting up Llama 2 locally involves a few preparatory steps but results in a powerful AI tool right at your fingertips. Here's a detailed guide to get you started:
Nvidia GPU Users: If you have an Nvidia GPU, your first step should be to install the CUDA toolkit to leverage GPU acceleration, enhancing Llama 2's performance. The toolkit can be downloaded from the official Nvidia website at CUDA Toolkit Download.
Model Download: Next, you'll need the Llama 2 model itself. The model can be downloaded from Hugging Face at the following link: Llama 2-13B Model Download. Ensure you save the model in a location that's easily accessible for later steps.
Open your Windows Terminal and use PowerShell for the following commands:
Clone the Llama.cpp repository:
git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
Prepare the build environment:
mkdir build
cd build
Generate the build files with CMake, enabling CUDA if you have an Nvidia GPU:
cmake .. -DLLAMA_CUBLAS=ON
cmake --build . --config Release
Navigate to the Release directory and set up the model:
cd bin/Release
mkdir models
mv Folder\Where\You\Downloaded\The\Model .\models
Run Llama 2 with a test prompt to ensure everything is set up correctly:
.\main.exe -m .\models\llama-2-13b-chat.ggmlv3.q4_0.bin --color -p "Hello, how are you, llama?" 2> $null
The 2> $null part of the command is used to suppress debug messages in the terminal, keeping the output clean.
To streamline the process of running Llama 2, you can define a PowerShell function:
Open your PowerShell profile with a text editor, for example:
notepad $PROFILE
Add the following function to your profile, adjusting paths as necessary:
function llama {
.\main.exe -m .\models\llama-2-13b-chat.ggmlv3.q4_0.bin -p $args 2> $null
}
This function allows you to run Llama 2 prompts more conveniently by typing llama "your prompt here" in the PowerShell terminal.
By following these steps, Windows users can enjoy the capabilities of Llama 2 locally, leveraging the power of AI for a variety of tasks without the need for an internet connection. This setup not only democratizes access to advanced AI models but also provides a personal, customizable AI experience.
