","html":"We have some exciting news to share this month!
\nDVC is going to PyCon 2019! It is the first\nconference that we attend as a team. When we say ‘team’ — we mean it. Our\nengineers are flying from all over the globe to get together offline and catch\nup with fellow Pythonistas.
\nThe speaker pipeline is\namazing! DVC creator Dmitry Petrov is giving a talk on\nMachine learning model and dataset versioning practices.
\nStop by our booth at the Startup Row on Saturday, May 4, reach out and let us\nknow that you are willing to chat, or simply find a person with a huge DVC owl\non their shirt!
\nSpeaking of the owls — DVC has done some rebranding recently and we love our new\nlogo. Special thanks to 99designs.com for building a\ngreat platform for finding trusted designers.
\n\n \n \n\n DVC is moving fast (almost as fast as my two-year-old). We do our best to keep\nup and totally love all the buzz in our community channels lately!
\nHere is a number of interesting reads that caught our eye:
\n![\"A](\"/uploads/images/2019-04-18/walkthrough-of-dvc.png\")
\n A great article about using DVC with a quite advanced scenario and docker. If\nyou haven’t had a chance to try DVC.org yet — this is a great\ncomprehensive read on why you should do so right away.
\n\n![\"The](\"/uploads/images/2019-04-18/the-state-of-machine-learning-operations.jpeg\")
\n A short (only 8 minutes!) and inspiring talk by Alejandro Saucedo at FOSDEM.\nAlejandro covers the key trends in machine learning operations, as well as most\nrecent open source tools and frameworks. Focused on reproducibility, monitoring\nand explainability, this lightning talk is a great snapshot of the current state\nof ML operations.
\n![\"Interview](\"/uploads/images/2019-04-18/interview-with-kaggle-grandmaster.jpeg\")
\n \n\nThere is no way you will become Kaggle Master and not learn how to approach\nanew, the unknown problem in a fast hacking way with a very high number of\niterations per unit of time. This skill in the world of competitive learning\nis the question of survival
\n
There are lots of hidden gems in our Discord community discussions. Sometimes\nthey are scattered all over the channels and hard to track down.
\nWe are sifting through the issues and discussions and share with you the most\ninteresting takeaways.
\nrequirements.txt).No server licenses for DVC. It is 100% free and open source.
\nI am trying to version control datasets and models with >10 GB (Potentially even\nbigger). Can DVC handle this?
\nThere is no limit. None enforced by DVC itself. It depends on the size of your\nlocal or remote storages. You\nneed to have some space available on S3, your SSH server or other storage you\nare using to keep these data files, models and their version, which you would\nlike to store.
\nHow does it connect them? Does it see that there is a dependency which is\noutputted from the first run?
\nDVC figures out the pipeline by looking at the dependencies and outputs of the\nstages. For example, having the following:
\n| \n | $ dvc run -f download.dvc \\ | \n
| \n | -o joke.txt \\ | \n
| \n | \"curl https://geek-jokes.sameerkumar.website/api > joke.txt\" | \n
| \n | $ dvc run -f duplicate.dvc \\ | \n
| \n | -d joke.txt \\ | \n
| \n | -o dulpicate.txt \\ | \n
| \n | \"cat joke.txt joke.txt > duplicate.txt\" | \n
you will end up with two stages:
download.dvc and duplicate.dvc. The\ndownload one will have joke.txt as an output . The duplicate one defined\njoke.txt as a dependency, as it is the same file. DVC detects that and creates\na pipeline by joining those stages.\nYou can inspect the content of each stage file\nhere (they are human\nreadable).
\n(e.g. in one repo
run dvc pull -r my_remote to pull some data and running the\nsame command in a different git repo should also pull the same)\nYes! It’s a frequent scenario for multiple repos to share remotes and even local\ncache. DVC file serves as a link to the actual data. If you add the same DVC\nfile (e.g.
data.dvc) to the new repo and do dvc pull -r remotename data.dvc-\nit will fetch data. You have to use dvc remote add first to specify the\ncoordinates of the remote storage you would like to share in every project.\nAlternatively (check out the question below), you could use --global to\nspecify a single default remote (and/or cache dir) per machine.\nUse
--global when you specify the remote settings. Then remote will be visible\nfor all projects on the same machine. --global — saves remote configuration to\nthe global config (e.g. ~/.config/dvc/config) instead of a per project one —\n.dvc/config. See more details\nhere.\nWe would recommend to skim through our\nget started tutorial, to summarize the data\nversioning process of DVC:
\ndvc add /\ndvc import) , or run a command to generate files:$ dvc run --out file.csv \"wget https://example.com/file.csv\"gitgit checkout v1.0)dvc checkout to retrieve all the files related by those stage filesAll your files (with each different version) are stored in a
.dvc/cache\ndirectory, that you sync with a remote file storage (for example, S3) using the\ndvc push or dvc pull commands (analogous to a git push / git pull, but\ninstead of syncing your .git, you are syncing your .dvc directory) on a\nremote repository (let’s say an S3 bucket).\nIf you need to move your dvc file somewhere, it is pretty easy, even if done\nmanually:
\n| \n | $ mv my.dvc data/my.dvc | \n
| \n | # and now open my.dvc with your favorite editor and change wdir in it to 'wdir: ../'. | \n
dvc push of a file to a remote. On the remote there is created a directory called 8f with a file inside called 2ec34faf91ff15ef64abf3fbffa7ee. The original CSV file doesn’t appear on the remote. Is that expected behaviour?This is an expected behavior. DVC saves files under the name created from their\nchecksum in order to prevent duplication. If you delete “pushed” file in your\nproject directory and perform
dvc pull, DVC will take care of pulling the file\nand renaming it to “original” name.\nBelow are some details about how DVC cache works, just to illustrate the logic.\nWhen you add a data source:
\n| \n | $ echo \"foo\" > data.txt | \n
| \n | $ dvc add data.txt | \n
It computes the (md5) checksum of the file and generates a DVC file with related\ninformation:
\n| \n | md5: 3bccbf004063977442029334c3448687 | \n
| \n | outs: | \n
| \n | - cache: true | \n
| \n | md5: d3b07384d113edec49eaa6238ad5ff00 | \n
| \n | metric: false | \n
| \n | path: data.txt | \n
| \n | wdir: .. | \n
The original file is moved to the cache and a link or copy (depending on your\nfilesystem) is created to replace it on your working space:
\n| \n | .dvc/cache | \n
| \n | └── d3 | \n
| \n | └── b07384d113edec49eaa6238ad5ff00 | \n
Absolutely! There are three ways you could interact with DVC:
\nfrom dvc.main import main and use it with regular CLI logic like\nret = main(‘add’, ‘foo’)dvc/repo and dvc/command in our source to get a\ngrasp of it). It is not officially public yet, and we don’t have any special\ndocs for it, but it is fairly stable and could definitely be used for a POC.\nWe’ll add docs and all the official stuff for it in the not-so-distant\nfuture.dvc run and a graph of tasks? Basically what would like extremely minimal DVC invasion into my GIT repo for an existing machine learning application?There are two options:
\ndvc add to track models and/or input datasets. It should be enough if\nyou use git commit on DVC files produced by dvc add. This is the very\nminimum you can get with DVC and it does not require using DVC run. Check the\nfirst part (up to the Pipelines/Add transformations section) of the DVC\nget started.--no-exec in dvc run and then just dvc commit and\ngit commit the results. That way you’ll get your DVC files with all the\nlinkages, without having to actually run your commands through DVC.If you have any questions, concerns or ideas, let us know\nhere and our stellar team will get back to you in no\ntime.
