🛠️ Installation

Prerequisites

• Python 3.11 or higher (recommended)
• Git
• CUDA-compatible GPU (optional, for GPU acceleration)
• Environment Manager: Choose one of the following:
  • Python venv (built-in)
  • Conda/Miniconda (recommended for scientific computing)

Quick Installation with uv (Recommended)

DNALLM-Suite uses uv for dependency management and packaging.

What is uv is a fast Python package manager that is 10-100x faster than traditional tools like pip.

Method 1: Using venv + uv

# Clone repository
git clone https://github.com/zhangtaolab/DNALLM.git
cd DNALLM

# Create virtual environment
python -m venv .venv

# Activate virtual environment
source .venv/bin/activate  # Linux/MacOS
# or
.venv\Scripts\activate     # Windows

# Upgrade pip (recommended)
pip install --upgrade pip

# Install uv in virtual environment
pip install uv

# Install DNALLM with base dependencies
uv pip install -e '.[base]'

# For MCP server support (optional)
uv pip install -e '.[mcp]'

# Verify installation
python -c "import dnallm; print('DNALLM installed successfully!')"

Method 2: Using conda + uv

# Clone repository
git clone https://github.com/zhangtaolab/DNALLM.git
cd DNALLM

# Create conda environment
conda create -n dnallm python=3.12 -y

# Activate conda environment
conda activate dnallm

# Install uv in conda environment
conda install uv -c conda-forge

# Install DNALLM with base dependencies
uv pip install -e '.[base]'

# For MCP server support (optional)
uv pip install -e '.[mcp]'

# Verify installation
python -c "import dnallm; print('DNALLM installed successfully!')"

GPU Support

For GPU acceleration, install the appropriate CUDA version:

# For venv users: activate virtual environment
source .venv/bin/activate  # Linux/MacOS
# or
.venv\Scripts\activate     # Windows

# For conda users: activate conda environment
# conda activate dnallm

# CUDA 12.4 (recommended for recent GPUs)
uv pip install -e '.[cuda124]'

# Other supported versions: cpu, cuda121, cuda126, cuda128
# Nvidia 5090 Please use cuda128 & torch==2.7
uv pip install -e '.[cuda128]'

Native Mamba Support

Native Mamba architecture runs significantly faster than transformer-compatible Mamba architecture, but native Mamba depends on Nvidia GPUs.

If you need native Mamba architecture support, after installing DNALLM dependencies, use the following command:

# For venv users: activate virtual environment
source .venv/bin/activate  # Linux/MacOS

# For conda users: activate conda environment
# conda activate dnallm

# Ensure CUDA path is set correctly (nvcc version must match your PyTorch CUDA version)
export PATH=/usr/local/cuda-12/bin:$PATH
nvcc -V  # Verify CUDA compiler version

# Install Mamba support
uv pip install -e '.[mamba]' --no-cache-dir --no-build-isolation --link-mode=copy

# If encounter network issue, using the special install script for mamba (optional)
sh scripts/install_mamba.sh  # select github proxy

Note: The nvcc version must match your PyTorch CUDA version. For example, if you installed PyTorch with CUDA 12.8, you need nvcc from CUDA 12.x. Mismatched versions will cause build failures.

Please ensure your machine can connect to GitHub, otherwise Mamba dependencies may fail to download.

Note that Plant DNAMamba, Caduceus, PlantCaduceus, PlantCAD2, Jamba-DNA, JanusDNA models are all based on Mamba architecture. Therefore, the training and inference of these models can be accelerated by installing the native mamba support.

Install Dependencies for Special Models

Several models require extra dependencies to train or inference.

These models are listed below:

Models	Model Type	Source	Dependencies
EVO-1	CausalLM	Hugging Face	GitHub

The installation method for the dependencies of these models can be found here.

🚀 Quick Start

model, tokenizer = load_model_and_tokenizer(
    model_name, task_config=configs["task"], source="huggingface"
)

# Initialize inference engine
inference_engine = DNAInference(
    config=configs, model=model, tokenizer=tokenizer
)

# Make inference
sequence = "AATATATTTAATCGGTGTATAATTTCTGTGAAGATCCTCGATACTTCATATAAGAGATTTTGAGAGAGAGAGAGAACCAATTTTCGAATGGGTGAGTTGGCAAAGTATTCACTTTTCAGAACATAATTGGGAAACTAGTCACTTTACTATTCAAAATTTGCAAAGTAGTC"
inference_result = inference_engine.infer(sequence)
print(f"Inference result: {inference_result}")

2. In-silico Mutagenesis Analysis

from dnallm import Mutagenesis

# Initialize mutagenesis analyzer
mutagenesis = Mutagenesis(config=configs, model=model, tokenizer=tokenizer)

    datasets=dataset
)

# Start training
trainer.train()
