Data Version Control or DVC is an open-source tool for data science and machine learning projects. Key features:

  1. Simple command line Git-like experience. Does not require installing and maintaining any databases. Does not depend on any proprietary online services.
  2. Management and versioning of datasets and machine learning models. Data can be saved in S3, Google cloud, Azure, Alibaba cloud, SSH server, HDFS, or even local HDD RAID.
  3. Makes projects reproducible and shareable; helping to answer questions about how a model was built.
  4. Helps manage experiments with Git tags/branches and metrics tracking.

DVC aims to replace spreadsheet and document sharing tools (such as Excel or Google Docs) frequently used as both knowledge repositories and team ledgers. DVC also replaces both ad-hoc scripts to track, move, and deploy different model versions and ad-hoc data file suffixes and prefixes.

How DVC works

We encourage you to read our Get Started guide to better understand what DVC is and how it can fit your scenarios.

The easiest (but not perfect!) analogy to describe it: DVC is Git (or Git-LFS to be precise) & Makefiles made right and tailored specifically for ML and Data Science scenarios.

  1. Git/Git-LFS part - DVC helps store and share data artifacts and models, connecting them with a Git repository.
  2. Makefiles part - DVC describes how one data or model artifact was built from other data and code.

DVC usually runs along with Git. Git is used as usual to store and version code (including DVC meta-files). DVC helps to store data and model files seamlessly out of Git, while preserving almost the same user experience as if they were stored in Git itself. To store and share the data cache, DVC supports multiple remotes - any cloud (S3, Azure, Google Cloud, etc) or any on-premise network storage (via SSH, for example).


The DVC pipelines (computational graph) feature connects code and data together. It is possible to explicitly specify all steps required to produce a model: input dependencies including data, commands to run, and output information to be saved. See the quick start section below or the Get Started tutorial to learn more.

Quick start

Please read Get Started guide for a full version. Common workflow commands include:

Step Command
Track data
$ git add
$ dvc add
Connect code and data by commands
$ dvc run -n prepare -d -o images/ unzip -q
$ dvc run -n train -d images/ -d -o model.p python
Make changes and reproduce
$ vi
$ dvc repro model.p.dvc
Share code
$ git add .
$ git commit -m 'The baseline model'
$ git push
Share data and ML models
$ dvc remote add myremote -d s3://mybucket/image_cnn
$ dvc push


There are four options to install DVC: pip, Homebrew, Conda (Anaconda) or an OS-specific package. Full instructions are available here.

Snap (Snapcraft/Linux)


snap install dvc --classic

This corresponds to the latest tagged release. Add --beta for the latest tagged release candidate, or --edge for the latest main version.

Choco (Chocolatey/Windows)


choco install dvc

Brew (Homebrew/Mac OS)


brew install dvc

Conda (Anaconda)


conda install -c conda-forge mamba # installs much faster than conda
mamba install -c conda-forge dvc

Depending on the remote storage type you plan to use to keep and share your data, you might need to install optional dependencies: dvc-s3, dvc-azure, dvc-gdrive, dvc-gs, dvc-oss, dvc-ssh.

pip (PyPI)


pip install dvc

Depending on the remote storage type you plan to use to keep and share your data, you might need to specify one of the optional dependencies: s3, gs, azure, oss, ssh. Or all to include them all. The command should look like this: pip install dvc[s3] (in this case AWS S3 dependencies such as boto3 will be installed automatically).

To install the development version, run:

pip install git+git://



Self-contained packages for Linux, Windows, and Mac are available. The latest version of the packages can be found on the GitHub releases page.

Ubuntu / Debian (deb)

sudo wget -O /etc/apt/sources.list.d/dvc.list
sudo apt-get update
sudo apt-get install dvc

Fedora / CentOS (rpm)

sudo wget -O /etc/yum.repos.d/dvc.repo
sudo yum update
sudo yum install dvc
