Data Version Control or DVC is a command line tool and VS Code Extension
_ to help you develop reproducible machine learning projects:
Store them in your cloud storage but keep their version info in your Git repo.
When you make changes, only run the steps impacted by those changes.
Please read our `Command Reference <https://dvc.org/doc/command-reference>`_ for a complete list.
A common CLI workflow includes:
+-----------------------------------+----------------------------------------------------------------------------------------------------+
| Task | Terminal |
+===================================+====================================================================================================+
| Track data | | $ git add train.py params.yaml
|
| | | $ dvc add images/
|
+-----------------------------------+----------------------------------------------------------------------------------------------------+
| Connect code and data | | $ dvc stage add -n featurize -d images/ -o features/ python featurize.py
|
| | | $ dvc stage add -n train -d features/ -d train.py -o model.p -M metrics.json python train.py
|
+-----------------------------------+----------------------------------------------------------------------------------------------------+
| Make changes and experiment | | $ dvc exp run -n exp-baseline
|
| | | $ vi train.py
|
| | | $ dvc exp run -n exp-code-change
|
+-----------------------------------+----------------------------------------------------------------------------------------------------+
| Compare and select experiments | | $ dvc exp show
|
| | | $ dvc exp apply exp-baseline
|
+-----------------------------------+----------------------------------------------------------------------------------------------------+
| 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
|
+-----------------------------------+----------------------------------------------------------------------------------------------------+
We encourage you to read our `Get Started
<https://dvc.org/doc/get-started>`_ docs to better understand what DVC
does and how it can fit your scenarios.
The closest analogies to describe the main DVC features are these:
Git is employed as usual to store and version code (including DVC meta-files as placeholders for data).
DVC stores data and model files <https://dvc.org/doc/start/data-management>
_ seamlessly in a cache outside of Git, while preserving almost the same user experience as if they were in the repo.
To share and back up the data cache, DVC supports multiple remote storage platforms - any cloud (S3, Azure, Google Cloud, etc.) or on-premise network storage (via SSH, for example).
|Flowchart|
DVC pipelines <https://dvc.org/doc/start/data-management/data-pipelines>
_ (computational graphs) connect code and data together.
They specify all steps required to produce a model: input dependencies including code, data, commands to run; and output information to be saved.
Last but not least, DVC Experiment Versioning <https://dvc.org/doc/start/experiments>
_ lets you prepare and run a large number of experiments.
Their results can be filtered and compared based on hyperparameters and metrics, and visualized with multiple plots.
.. _VS Code Extension
:
|VS Code|
To use DVC as a GUI right from your VS Code IDE, install the DVC Extension <https://marketplace.visualstudio.com/items?itemName=Iterative.dvc>
_ from the Marketplace.
It currently features experiment tracking and data management, and more features (data pipeline support, etc.) are coming soon!
|VS Code Extension Overview|
Note: You'll have to install core DVC on your system separately (as detailed
below). The Extension will guide you if needed.
There are several ways to install DVC: in VS Code; using snap
, choco
, brew
, conda
, pip
; or with an OS-specific package.
Full instructions are available here <https://dvc.org/doc/get-started/install>
_.
|Snap|
.. code-block:: bash
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|
.. code-block:: bash
choco install dvc
|Brew|
.. code-block:: bash
brew install dvc
|Conda|
.. code-block:: bash
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
.
|PyPI|
.. code-block:: bash
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:
.. code-block:: bash
pip install git+git://github.com/iterative/dvc
|Packages|
Self-contained packages for Linux, Windows, and Mac are available.
The latest version of the packages can be found on the GitHub releases page <https://github.com/iterative/dvc/releases>
_.
Ubuntu / Debian (deb) ^^^^^^^^^^^^^^^^^^^^^ .. code-block:: bash
sudo wget https://dvc.org/deb/dvc.list -O /etc/apt/sources.list.d/dvc.list wget -qO - https://dvc.org/deb/iterative.asc | sudo apt-key add - sudo apt update sudo apt install dvc
Fedora / CentOS (rpm) ^^^^^^^^^^^^^^^^^^^^^ .. code-block:: bash
sudo wget https://dvc.org/rpm/dvc.repo -O /etc/yum.repos.d/dvc.repo sudo rpm --import https://dvc.org/rpm/iterative.asc sudo yum update sudo yum install dvc
