• package handles
    • Packages are referenced by a handle of the form OWNER/NAME
    • Teams packages include a prefix, TEAM:OWNER/NAME
  • Short hashes
    • Commands that take hashes support "short hashes", up to uniqueness. In practice, 6-8 characters is sufficient to achieve uniqueness.
      quilt install akarve/examples -x 4594b5
      # matches hash 4594b58d64dd9c98b79b628370618031c66e80cbbd1db48662be0b7cac36a74e
  • Requirements file (quilt.yml)
    $ quilt install [@FILENAME]
    # quilt.yml is the default if @filename is absent
    • Installs a list of packages specified by a YAML file. The YAML file must contain a packages node with a list of packages:
        - USER/PACKAGE[/SUBPACKAGE][:h[ash]|:t[ag]|:v[ersion]][:HASH|TAG|VERSION]
    • Example
      - vgauthier/DynamicPopEstimate   # get latest
      - danWebster/sgRNAs:a972d92      # get a specific version via hash
      - akarve/sales:tag:latest        # get a specific version via tag
      - asah/snli:v:1.0                # get a specific version via version


Team users

See teams docs for additional commands and syntax.

Core: build, push, and install packages

Command line Python Description
quilt build USER/PACKAGE PATH"USER/PACKAGE", "PATH") PATH may be a build.yml file or a directory. If a directory is given, Quilt will internally generate a build file (useful, e.g. for directories of images). build.yml is for users who want fine-grained control over parsing.
quilt push USER/PACKAGE [--public │ --team] quilt.push("USER/PACKAGE", is_public=False, is_team=False) Stores the package in the registry
quilt install USER/PACKAGE[/SUBPATH/...] [-x HASH │ -t TAG │ -v VERSION] quilt.install("USER/PACKAGE[/SUBPATH/...]", hash="HASH", tag="TAG", version="VERSION") Installs a package or sub-package
quilt install @FILE=quilt.yml Not supported Installs all specified packages using the requirements syntax (above)
quilt delete USER/PACKAGE quilt.delete("USER/PACKAGE") Removes the package from the registry. Does not delete local data.


Command line Python Description
quilt log USER/PACKAGE quilt.log(USER/PACKAGE) Display push history
quilt version list USER/PACKAGE quilt.version_list(USER/PACKAGE) Display versions of a package
quilt version add USER/PACKAGE VERSION HASH quilt.version_add(USER/PACKAGE, VERSION, HASH) Associate a version with a hash
quilt tag list USER/PACKAGE quilt.tag_list(USER/PACKAGE) List available tags
quilt tag add USER/PACKAGE TAG HASH quilt.tag_add(USER/PACKAGE, TAG, HASH) Associate a tag with a hash
quilt tag remove USER/PACKAGE TAG quilt.tag_remove(USER/PACKAGE, TAG) Remove a tag

Instances, hashes, tags, and versions

  • A package instance is a package handle plus a hash. akarve/sales:fc7f0b is an instance. Instances are immutable.
  • Hashes are automatically generated by Quilt for each package build.
  • Tags are human-readable strings associated with a package instance. Tags can be altered to point to different instances of the same package. The most recent build is automatically tagged "latest".
  • Versions are human-readable strings associated with a package instance. Unlike tags, versions can only ever point to a single package instance.


Command line Python Description
quilt login [TEAM] quilt.login(["TEAM"]) Authenticate to a registry
quilt access list USER/PACKAGE quilt.access_list("USER/PACKAGE") List user who have access to a package
quilt access add USER/PACKAGE USER_OR_GROUP quilt.access_add("USER/PACKAGE", "USER_OR_GROUP") Grant read access to a user or group (one of public or team)
quilt access remove USER_OR_GROUP quilt.access_remove("USER/PACKAGE", "USER_OR_GROUP") Remove read access

Local storage

Command line Python Description
quilt ls List installed packages
quilt rm USER/PACKAGE quilt.rm("USER/PACKAGE") Remove a package from local storage (but not from the registry)
Command line Python Description
quilt search "SEARCH STRING""SEARCH STRING") Search registry for packages by user or package name

Export a package or subpackage

Command line Python Description
quilt export USER/PACKAGE quilt.export("USER/PACKAGE") Export data to current dir
quilt export USER/PACKAGE DEST quilt.export("USER/PACKAGE", "DEST") Export data to specified destination
quilt export USER/PACKAGE [DEST] --force quilt.export("USER/PACKAGE", "DEST", force=True) Overwrite files at destination

If a node references raw (file) data, symlinks may be used instead of copying data when exporting. But be cautious when using symlinks for export:

  • When using any OS
    • If a file is edited, it may corrupt the local quilt repository
      • Preventing this is up to you
  • When using Windows
    • Symlinks may not be supported
    • Symlinks may require special permissions
    • Symlinks may require administrative access (even if an administrator has the appropriate permissions)
Command line Python Description
quilt export USER/PACKAGE [DEST] [--symlinks] quilt.export("USER/PACKAGE", "DEST", symlinks=True) Export data, using symlinks where possible

Import and use data

For a package in the public cloud:

from import PACKAGE

For a package in a team registry:

from import PACKAGE

Using packages

Packages contain three types of nodes:

  • PackageNode - the root of the package tree
  • GroupNode - like a folder; may contain one or more GroupNode or DataNode objects
  • DataNode - a leaf node in the package; contains actual data

Working with package contents

  • List node contents with dot notation: PACKAGE.NODE.ANOTHER_NODE
  • Retrieve the contents of a DataNode with _data(), or simply (): PACKAGE.NODE.ANOTHER_NODE()
    • Columnar data (XLS, CSV, TSV, etc.) returns as a pandas.DataFrame
    • All other data types return a string to the path of the object in the package store

Enumerating package contents

  • quilt.inspect("USER/PACKAGE") shows package columns, types, and shape
  • NODE._keys() returns a list of all children
  • NODE._data_keys() returns a list of all data children (leaf nodes containing actual data)
  • NODE._group_keys() returns a list of all group children (groups are like folders)
  • NODE._items() returns a generator of the node's children as (name, node) pairs.


from import wine
In [7]: wine._keys()
Out[7]: ['README', 'raw', 'tables']
In [8]: wine._data_keys()
Out[8]: ['README']
In [9]: wine._group_keys()
Out[9]: ['raw', 'tables']

Editing Package Contents

  • PACKAGENODE._set(PATH, VALUE) sets a child node. PATH is an array of strings, one for each level of the tree. VALUE is the new value. If it's a Pandas dataframe, it will be serialized. A string will be interpreted as a path to a file that contains the data to be packaged. Common columnar formats will be serialized into data frames. All other file formats, e.g. images, will be copied as-is.
  • GROUPNODE._add_group(NAME) adds an empty GroupNode with the given name to the children of GROUPNODE.


import pandas as pd
import quilt'USER/PKG') # create new, empty packckage
from import PKG as pkg
pkg._set(['data'], pd.DataFrame(data=[1, 2, 3]))
pkg._set(['foo'], "example.txt")'USER/PKG', pkg)

This adds a child node named data to the new empty package, with the new DataFrame as its value. Then it adds the contents of example.txt to a node called foo. Finally, it commits this change to disk by building the package with the modified object.

See the examples repo for additional usage examples.
