Get started

See details in Get Started.

Step	Command
Track code and data together	$ git add train.py $ dvc add images.zip
Connect code and data by commands	$ dvc run -d images.zip -o images/ unzip -q images.zip $ dvc run -d images/ -d train.py -o model.p python train.py
Make changes and reproduce	$ vi train.py $ 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 s3://mybucket/image_cnn $ dvc core.remote myremote $ dvc push

Installation

It could be installed using pip, Homebrew or an OS-specific package.

pip install dvc

Package

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

Homebrew

brew install iterative/homebrew-dvc/dvc

or:

brew cask install iterative/homebrew-dvc/dvc

Related technologies

1. Git-annex - DVC uses the idea of storing the content of large files (that you don't want to see in your Git repository) in a local key-value store and uses file hardlinks/symlinks instead of the copying actual files.
2. Git-LFS. - DVC is compatible with any remote storage (S3, Google Cloud, Azure, SSH, etc). DVC utilizes reflinks or hardlinks to avoid copy operation on checkouts which makes much more efficient for large data files.
3. Makefile (and it's analogues). DVC tracks dependencies (DAG).
4. Workflow Management Systems. DVC is a workflow management system designed specifically to manage machine learning experiments. DVC is built on top of Git.

DVC is compatible with Git for storing code and the dependency graph (DAG), but not data files cache. To store and share data files cache DVC supports remotes - any cloud (S3, Azure, Google Cloud, etc) or any on-premise network storage (via SSH, for example).
