Practical overview
When it fits
Use DNABERT when you want repository-level code and pretrained weights for DNA-sequence modeling, and can prepare data in the specified k-mer format and meet the documented Python, Linux, CUDA, and GPU requirements.
Who it is for
- Genomics researchers preparing DNA-sequence modeling workflows.
- Python practitioners fine-tuning transformer models on task-specific genomic data.
- Teams exploring k-mer-based pretraining or sequence analysis with GPU-backed Linux environments.
Documented uses
- Convert DNA sequences into k-mer representation with the provided seq2kmer function.
- Fine-tune a pretrained DNABERT model on task-specific sequence data.
- Pretrain a model using sequence data formatted to the repository’s examples.
- Use the repository’s examples and visualization tool when working with its models.
Requirements & limits
The repository is public and identifies its license as Apache-2.0. The README directs users to Hugging Face for DNABERT-3 through DNABERT-6 weights because the original download links expired.
- The README specifies Python 3.6, Linux x86_64, an NVIDIA GPU, driver version 410.48 or later, and CUDA 10.0 for its setup instructions.
- The repository’s data workflow expects k-mer-formatted sequences and provides a conversion function.
- GPU memory can affect batch-size choices; the README recommends adjusting batch size for different hardware.
- Apex is optional and is specified for mixed-precision training.
- DNABERT-2 is a distinct second-generation project, linked by the repository as a separate option.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up the DNABERT environment
Install DNABERT and its required Python packages in a Linux environment.
Before you start
- Anaconda/Conda
- Linux x86_64
- At least one NVIDIA GPU
- NVIDIA driver version 410.48 or later, compatible with CUDA 10.0
Steps
Create and activate a Python 3.6 environment with
conda create -n dnabert python=3.6andconda activate dnabert.Install PyTorch, torchvision, and CUDA Toolkit 10.0 with
conda install pytorch torchvision cudatoolkit=10.0 -c pytorch.Clone the DNABERT repository, enter its directory, and install it in editable mode with the command below.
python3 -m pip install --editable .Enter
examplesand install its requirements with the command below.python3 -m pip install -r requirements.txt
Expected outcome
The DNABERT package and example requirements are installed in the `dnabert` Conda environment.
Guide limitations
- The repository is described as under development.
- The documented setup targets Python 3.6 and CUDA Toolkit 10.0.
- Training batch sizes may need adjustment for GPUs with different specifications or memory.
- Installing NVIDIA Apex is optional and is documented for fp16 training.
