Mambaoutai is a powerful language model designed for smooth text generation in both French and English, along with coding tasks. It’s a culmination of extensive experimentation and training, resulting in a series of checkpoints made available for the community. In this guide, we’ll walk you through the steps to get started, explore its features, and troubleshoot potential issues.

Getting Started with Mambaoutai

Before jumping into the usage, ensure that you have the necessary tools installed. The following steps will help you set up Mambaoutai on your system.

Installation

• Install the Transformers library:

pip install git+https://github.com/huggingface/transformers@main

• Install necessary packages:

pip install causal-conv1d==1.2.0

pip install mamba-ssm==1.2.0

• Note: If these packages are not installed, an eager implementation will be utilized, which is not recommended.

Generating Text

Once you have everything installed, you can begin generating text. Here’s how you can do it:

from transformers import MambaConfig, MambaForCausalLM, AutoTokenizer
import torch

if model_has_instruct_data:  # use chat tokens
    prompt = "start_user Tell me something about Paris. end_message start_assistant"
else:
    prompt = "This is a text about Paris. Paris is"

tokenizer = AutoTokenizer.from_pretrained("lightonai/mambaoutai")
model = MambaForCausalLM.from_pretrained("lightonai/mambaoutai")
input_ids = tokenizer(prompt, return_tensors="pt")["input_ids"]
out = model.generate(input_ids, max_new_tokens=10)
print(tokenizer.batch_decode(out))

Understanding the Code – An Analogy

Imagine you are a chef in a high-tech kitchen, each ingredient representing different parts of your code:

• The Transformer library is like your all-in-one kitchen where you source your fresh ingredients—the context and structure you need to cook.
• The prompt acts as your recipe guide—depending on whether you want to whip up an instructional dish or something more generic, you prepare your ingredients accordingly.
• Tokenizer is your chopping board, processing and preparing your ingredients before cooking them to ensure they blend perfectly.
• Finally, the model itself is your oven, where all the prepared ingredients come together to create a delicious dish—text generated from your prompt.

Using Training Checkpoints

If you need to load specific checkpoints during training, here’s how to do that:

tokenizer = AutoTokenizer.from_pretrained("lightonai/mambaoutai", revision="pre-30000")
model = MambaForCausalLM.from_pretrained("lightonai/mambaoutai", revision="pre-30000")
input_ids = tokenizer("What is a mamba?", return_tensors="pt")["input_ids"]
out = model.generate(input_ids, max_new_tokens=10)
print(tokenizer.batch_decode(out))

Performing On-device Inference

Due to its relatively small size of 1.6B parameters, Mambaoutai can be conveniently run on a CPU. Here’s a step-by-step guide for running it on llama.cpp:

• Clone the llama.cpp repository:

git clone https://github.com/ggerganov/llama.cpp

• Navigate to the directory and compile:

cd llama.cpp
make

• Create a virtual environment and install the required dependencies:

conda create -n mamba-cpp python=3.10
conda activate mamba-cpp
pip install -r requirements/requirements-convert-hf-to-gguf.txt

• Download the model components and convert weights to GGUF format:

mkdir Mambaoutai
python convert-hf-to-gguf.py Mambaoutai

• Run inference with your chosen prompt:

main -m Mambaoutai/ggml-model-f16.gguf -p "Building a website can be done in 10 simple steps:"

Troubleshooting Tips

As you delve into using Mambaoutai, you may encounter some hiccups along the way. Here are some common troubleshooting ideas:

• Package Installation Issues: Make sure you deactivate any virtual environments before running installation commands to avoid conflicts.
• Model Loading Errors: When specifying revisions, ensure that the revision exists in the repository. Otherwise, double-check your input for typos.
• Performance Issues: If the model is running slower than expected, ensure that CUDA kernels are enabled and configurations are optimized.
