dvcfilesystem dvcfilesystem provides a pythonic file interface fsspec compatible for a dvc repo it is a read only filesystem hence it does not support any write operations like put_file cp rm mv mkdir etc class dvcfilesystem abstractfilesystem def __init__ self repo optional str none rev optional str none config optional dict str any none kwargs dvcfilesystem provides a unified view of all the files directories in your repository be it git tracked or dvc tracked or untracked in case of a local repository it can reuse the files in dvc cache cache and can otherwise stream from supported remote storage from dvc api import dvcfilesystem opening a local repository fs dvcfilesystem path to local repository opening a remote repository repo https github com treeverse example get started git fs dvcfilesystem repo rev main parameters repo optional url or local path to the dvc project if unspecified the dvc project in current working directory is used equivalent to the repo argument in dvc api open and dvc api read the parameter was renamed from url to repo in dvc 3 60 if you are using an older version and passing arguments by keyword replace use of url with repo rev optional git commit any revision such as a branch or a tag name a commit hash or an experiment name config optional config dictionary to pass through to the dvc project opening a file with fs open model pkl as f model pickle load f this is similar to dvc api open which returns a file like object note that unlike dvc api open the mode defaults to binary mode i e rb you can also specify encoding argument in case of text mode r reading a file text fs read_text get started data xml encoding utf 8 this is similar to dvc api read which returns the contents of the file as a string to get the binary contents of the file you can use read_bytes or cat_file contents fs read_bytes get started data xml listing all dvc tracked files recursively fs find detail false dvc_only true data data xml data features test pkl data features train pkl data prepared test tsv data prepared train tsv evaluation importance png model pkl this is similar to dvc ls recursive dvc only cli command note that the is considered as the root of the git repo you can specify sub paths to only return entries in that directory similarly there is fs ls that is non recursive listing all files including git tracked fs find detail false gitignore readme md data gitignore data data xml data features test pkl data features train pkl data prepared test tsv data prepared train tsv evaluation gitignore evaluation importance png evaluation plots confusion_matrix json evaluation plots precision_recall json evaluation plots roc json model pkl this is similar to dvc ls recursive cli command it returns all of the files tracked by dvc and git and if filesystem is opened locally it also includes the local untracked files downloading a file or a directory fs get_file data data xml data xml this downloads data data xml file to the current working directory as data xml file the dvc tracked files may be downloaded from the cache if it exists or may get streamed from the remote fs get data data recursive true this downloads all the files in data directory be it git tracked or dvc tracked into a local directory data similarly dvc might fetch files from remote if they don t exist in the cache using subrepos if you have initialized dvc in a subdirectory of the git repository use dvcfilesystem repo subrepos true to access the subdirectory from dvc api import dvcfilesystem repo https github com iterative monorepo example git by default dvc initialized in a subdirectory will be ignored fs dvcfilesystem repo rev develop fs find nlp detail false dvc_only true use subrepos true to list those files fs dvcfilesystem repo subrepos true rev develop fs find nlp detail false dvc_only true nlp data data xml nlp data features test pkl nlp data features train pkl nlp data prepared test tsv nlp data prepared train tsv nlp eval importance png nlp model pkl fsspec api reference as dvcfilesystem is based on fsspec it is compatible with most of the apis that it offers when dvc is installed in the same python environment as any other fsspec compatible library such as hugging face datasets dvcfilesystem will be used automatically when a dvc filesystem url is provided to fsspec function calls for more details check out the fsspec s api reference note that dvc urls contain the path to the file you wish to load relative to the root of the dvc project dvc urls should not contain a git repository url the git repository url is provided separately via the repo argument for dvcfilesystem when using dvc urls additional constructor arguments for dvcfilesystem such as repo or rev should be passed via the storage_options dictionary or as keyword arguments depending on the specific fsspec method behing called please refer to the fsspec documentation for specific details fsspec api examples for methods which take filesystem arguments as additional keyword arguments import fsspec fsspec open dvc workshop satellite data jan_train csv repo https github com treeverse dataset registry git openfile workshop
